Abstract
Previous observational studies revealed controversy about the effect of circulating antioxidants on risk of alopecia. In the present study, we investigated the causal relationships between diet-derived circulating antioxidants and 2 non-scarring alopecia using Mendelian randomization (MR). Instrumental variables for antioxidants (lycopene, retinol, ascorbate, β-carotene, α-tocopherol, and γ-tocopherol) were selected from published studies. Data for alopecia areata (AA) and androgenetic alopecia (AGA) was obtained from the FinnGen study project (R9 released in 2023), including 195 cases and 201,019 controls for AGA and 682 cases and 361,140 controls for AA. We used the inverse variance weighted method as the primary MR method. Three additional methods were used as sensitivity analysis to validate the robustness of the results. We found a causal relationship between absolute β-carotene levels and AGA risk (P = .039), but not with AA (P = .283). The results of Wald ratio showed a protective effect of absolute β-carotene levels against AGA, with per 0.1 ln-transformed β-carotene being associated with a 76% lower risk of AGA (OR: 0.24, 95% CI: 0.06-0.93). Based on the fixed effects inverse variance weighting results, we found that α-tocopherol was protective against both AGA (P = .026) and AA (P = .018). For each unit increase in α-tocopherol, the effects of change in AGA and AA were 0.02 (95% CI: 0.00-0.61) and 0.10 (95% CI: 0.01-0.67), respectively. The results did not reveal any other causal relationships. Our study identified 3 causal associations of antioxidants with the risk of non-scarring alopecia. These results provide new insights into the prevention of non-scarring alopecia through diet.

Higher percentage of CD34+ stem cells and elevated efficacy in androgenetic alopecia treatment observed in CGF prepared from 640 nm laser-pretreated blood: A preliminary study. J Cosmet Dermatol 2024; 23:2249-2255. [PMID: 38429917 DOI: 10.1111/jocd.16249] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 01/31/2024] [Accepted: 02/15/2024] [Indexed: 03/03/2024]
Abstract
BACKGROUND Concentrated growth factor (CGF) injection has proven effective in treating androgenetic alopecia (AGA). The primary mechanism of CGF in treating AGA is thought to be the CD34+ stem cells and platelets-associated growth factors being injected into the scalp. CGF efficacy in treating AGA may rely on the activation level of these stem cells and platelets. The 640 nm laser is a United States Food and Drug Administration approved AGA treatment that activates follicle stem cells. Therefore, we hypothesize that pretreating CGF with a 640 nm laser may further activate CD34+ stem cells and platelets, thereby improving the efficacy of CGF in treating AGA. OBJECTIVE This study aims to investigate whether 640 nm laser pretreated CGF (640CGF) has a greater effect in treating AGA than 640 nm laser non-pretreated CGF (N640CGF) and evaluate whether 640 nm laser pretreatment changed CD34+ cell percentage. METHODS This study enrolled 10 patients (8 male, 2 female) with AGA aged 18-60 years who received CGF injections. The 640CGF group was pretreated with a 640 nm laser at an energy density of 4 J/cm2, with a 30 cm irradiation distance for 30 min. Half of the scalp was treated with 640CGF, whereas the other half was treated with N640CGF. The injection was prepared by a doctor who did not know which blood tube had been pretreated. The treatment efficacy was evaluated using a trichoscope 1 month after injection. RESULTS All 10 (100%) patients participated in the follow-up visit, and a higher quantity of new hairs was observed on the side injected with 640CGF than N640CGF (p = 0.019). Additionally, fewer malnourished hairs were observed on the 640CGF pretreated side (p = 0.015). No serious adverse events were reported. CONCLUSIONS A higher percentage of CD34+ stem cells and improved efficacy in AGA treatment could be observed with CGF prepared from 640 nm laser-pretreated blood.

Abstract
BACKGROUND This study aims to investigate the effects of a conditioned medium (CM) from human umbilical cord mesenchymal stem cells (HuMSCs) cultivated in gelatin sponge (GS-HuMSCs-CM) on hair growth in a mouse model. METHODS CM was collected from the HuMSCs cultivated in a monolayer or in a gelatin sponge. Vascular endothelial growth factor (VEGF), insulin-like growth factor-1 (IGF-1), keratinocyte growth factor (KGF), and hepatocyte growth factor (HGF) levels in CMs were measured by enzyme-linked immunosorbent assays (ELISAs). A hair loss model by a C57 BL/6J mouse was prepared. The effects of GS-HuMSCs-CM and HuMSCs on hair regrowth in mice were investigated by intradermal injection in the depilated back skin with normal saline (NS) as the control. The time for hair regrowth and full covering in depilated areas was observed, and the hair growth was evaluated histologically and by grossly measuring hair length and diameter. RESULTS Compared with monolayer cultured cells, the three-dimensional (3D) culture of HuMSCs in gelatin sponge drastically increased VEGF, IGF-1, KGF, and HGF production. GS-HuMSCs-CM and HuMSCs injection both promoted hair regeneration in mice, while GS-HuMSCs-CM presented more enhanced effects in hair length, hair diameter, and growth rate. GS-HuMSCs-CM significantly promoted angiogenesis in injected skin areas, which might also contribute to faster hair regrowth. CONCLUSION GS-HuMSCs-CM exerted significant effects on inducing hair growth and promoted skin angiogenesis in C57BL/6J mice.

Abstract
Androgenetic alopecia seriously affects the physical and mental health of patients. The main clinical therapeutic agent, minoxidil tincture, is challenged by solvent irritation and dose-dependent side effects. Our recent work has identified a biosafety natural product, cedrol, that is synergistic in combination with minoxidil, thereby improving medication safety by substantially reducing the clinical dose of minoxidil. In addition, ccross-linked CD-MOF were designed as carriers for hair follicle delivery, and γ-CD in the carriers was cross-linked by diphenyl carbonate with covalent bonds to protect the CD-MOF from rapid disintegration in an aqueous environment. This improved nanocarrier has a drug loading of 25%, whereas nanocarriers increased drug delivery to the hair follicles through ratchet effect, and increased human dermal papilla cells uptake of drugs via endocytosis pathways mainly mediated by lattice proteins, energy-dependent active transport, and lipid raft-dependent, thus improved cell viability, proliferation, and migration, followed by significantly enhancing the anti-androgenetic alopecia effect, with cedrol focusing on inhibiting 5α-reductase and activating Shh/Gli pathway, and minoxidil, which up-regulated VEGF, down-regulated TGF-β, and activated ERK/AKT pathway. This drug combination provides a new therapeutic strategy for androgenetic alopecia, while the newly developed cross-linked CD-MOF has been shown to serve as a promising follicular delivery vehicle.

Abstract
This study reviewed the current knowledge on the epidemiology, pathophysiology, clinical presentations, diagnosis, treatment, quality-of-life assessment and recent trends in androgenetic alopecia (AGA). Relevant articles on AGA from PubMed, Google Scholar, Medline and Scopus from 1950 to 2024 were obtained and scrutinized.. Key search words included each term like 'androgenetic alopecia', 'androgenic alopecia', 'pattern baldness' and 'pattern hair loss' AND each term like 'epidemiology', 'pathophysiology', 'genetics', 'hormones', 'micronutrient', 'stress and inflammation', 'growth factors', 'clinical features', 'staging', 'cardiovascular associations', 'diagnosis' and 'management' were used in the search. AGA is a non-scarring hair loss that is exemplified by a progressive decline of hair follicles, or non-functional or dead hair follicles in the scalp in a defined pattern. It is the most common hair loss, more common in men but can also present in younger age as premature AGA. Hormones, genetics, micronutrient deficiency, microinflammation and stress have been implicated, while psychosocial distress and cutaneous correlate of cardiovascular diseases have become sources of relentless research. AGA is a patterned hair loss that is more prevalent in Men. It results from the interactions between hormonal, genetic and other factors which determine the extent of hair loss and associated disorders (psychosocial and cardiovascular). As results of more research become available, the extent of AGA, its comorbidities as well as the full spectrum of their manifestations will continue to be sources of health education and more holistic examination by dermatologists and patients.

Androgenetic alopecia can be challenging to treat due to the wide range of available treatments, most of which are not based on evidence from clinical trials. In addition many of the options do not include androgenetic alopecia among the approved indications according to their summaries of product characteristics. A panel of 34 dermatologists from the Spanish Hair Disorders Society of the Spanish Academy of Dermatology and Venereology (AEDV) used the Delphi method to develop a consensus statement on the management of androgenetic alopecia. Over a 2-round process the experts agreed on 138 (86%) of the 160 proposed items, which were structured into 4 blocks of recommendations: general considerations, pharmacologic treatment, procedures and hair transplant, and special cases. The resulting consensus statement based on expert opinion of the scientific evidence can guide professionals in the routine management of androgenetic alopecia.

Abstract
BACKGROUND Topical minoxidil is the recommended first-line pharmacologic treatment for male and female pattern hair loss. However, low-dose oral minoxidil has been used off-label with good clinical efficacy and safety. AIM To compare the effectiveness and safety of topical minoxidil as a first-choice treatment of androgenetic alopecia versus 1 mg daily oral minoxidil. METHOD Sixty-five AGA patients were randomly allocated to receive either 5% topical solution or 1 mg/day oral minoxidil for 6 months. Treatment efficacy was evaluated by measuring hair diameter, photographic assessment, and patient self-assessment questionnaires. The safety of treatment was checked through history taking and physical examination. RESULTS Both topical and oral minoxidil groups showed significant improvement in hair diameter after 6 months of treatment (p < 0.001). However, there was no significant difference between the two groups. The photographic assessment demonstrated a significant improvement in hair density in the topical minoxidil group in all marked points located at 12 cm (p = 0.025), 16 cm (p = 0.034), and 24 cm (p = 0.014) distance from the glabella but not in the oral minoxidil group. Nevertheless, the difference between the two groups was not significant. In each group, over 60% of patients expressed satisfaction with their treatments, and no significant difference was detected between the two groups. CONCLUSION Although topical minoxidil has a better overall therapeutic effect than 1 mg oral minoxidil, the difference between the two groups was not significant. Therefore, 1 mg oral minoxidil may be as effective and safe as standard topical minoxidil in female and male pattern hair loss.

Abstract
Minoxidil is widely used for treating Androgenic Alopecia, but its low hydrophilicity promotes the use of co-solvents in commercial formulations, which could then cause skin irritations. Nano-drug delivery systems have been developed to improve the solubility of lipophilic molecules and increase the concentration of drugs in hair follicles, thereby minimizing side effects. Chitosan (CS) and Methylated Aminobenzyl Carboxymethyl Chitosan (MCS) nanoparticles containing Minoxidil were prepared and evaluated for their physicochemical properties, drug release profile, skin permeation, cytotoxicity, and animal hair growth. The results showed that MCS nanoparticles had a 60 % drug release compared to CS nanoparticles, with almost complete release in 2 h. MCS nanoparticles also showed a 20 % drug permeation from skin compared to 70 % for CS nanoparticles in 24 h. In 48 and 72 h, CS and MCS nanoparticles didn't exhibit any significant cytotoxicity. Animal study revealed a significant increase in hair growth from MCS nanoparticles compared to the commercial formulation in fourteen days. However, MCS nanoparticles were less efficient compared to CS nanoparticles. The use of MCS in nano-drug delivery systems is expected to continue to gain importance due to its ability to enhance the solubility of hydrophobic drugs, particularly in the treatment of skin diseases.

Abstract
Given that current androgenetic alopecia (AGA) medications have adverse effects such as sexual dysfunction and drug dependence, researchers are actively exploring natural bioactive ingredients and innovative approaches (e.g., transdermal drug delivery systems) to effectively combat hair loss with minimal side effects. Herein, we develop a new transdermal drug delivery system incorporating globefish skin collagen peptides with dissolving microneedles (GSCPs-MNs) for hair regrowth. These microneedles generate skin micro-wounds upon application, which not only improves the efficiency of bioactive ingredients delivery, but also stimulates signals involved in hair follicle (HF) regeneration. Our in vivo study shows that minimally invasive implanted GSCPs-MNs are more effective than topical GSCPs in reducing inflammation and promoting collagen formation. Additionally, the upregulation of vascular markers including VEGF and CD31 alongside the downregulation of TNF-α, IL-1β, and malondialdehyde (MDA) index indicate that GSCPs-MNs can significantly alleviate inflammation and oxidation, as well as promoting vascularization and HF functionalization. Overall, our findings suggest that GSCPs-MNs can effectively promote hair regrowth in AGA mice, which offer excellent prospects for the development of new therapeutics and cosmetic supplements for hair loss, along with the combined drug delivery optimization, which could alleviate hair loss in patients with AGA.

Cyanidin-3-O-glucoside and its derivative vitisin A alleviate androgenetic alopecia by exerting anti-androgen effect and inhibiting dermal papilla cell apoptosis. Eur J Pharmacol 2024; 963:176237. [PMID: 38048982 DOI: 10.1016/j.ejphar.2023.176237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 11/16/2023] [Accepted: 11/28/2023] [Indexed: 12/06/2023]
Abstract
Androgenetic alopecia (AGA), one of the most common forms of hair loss, lacks satisfactory treatment methods in modern society. This study employed an experimental design combining in vitro and in vivo approaches to explore the effects of Cyanidin-3-O-glucoside (C3G) and Carboxypyranocyanidin-3-O-glucoside (Vitisin A) on AGA. In human dermal papilla cells (HDPCs), both anthocyanins demonstrated inhibitory effects on androgen receptors, significantly reduced dihydrotestosterone (DHT) induced apoptosis of HDPCs, and regulated the secretion of Fibroblast growth factor 7 and Transforming growth factor beta 1. In vitro transdermal experiment revealed that both C3G and Vitisin A could penetrate mice skin, aided by the application of cream. Furthermore, in vivo experiments with mice indicated that application of C3G or Vitisin A cream effectively improved hair follicles miniaturization, regression, and apoptosis caused by DHT. The repression of Wnt10b and β-catenin expression induced by DHT was prevented by C3G and Vitisin A in both cell and mouse model. Consequently, these findings suggest that C3G and Vitisin A could be considered as alternative methods for alleviating AGA.

Abstract
BACKGROUND Nowadays, the majority of the population suffers from the problem of hair loss. It leads to disturbed mental health, lower self-confidence, and a lot more problems. A lot of the hair loss therapies available are not reliable and lead to recurrence and side effects after some time. Cannabinoids (CBD) have recently become quite popular for their benefits against hair loss. CBD oil preparations have been used both internally and externally for oral and topical use, respectively. Due to the presence of the endocannabinoid system (ECS) in the body, which naturally targets CB1 and CB2 receptors, the control of hair fall is possible. CBD is used topically for hair loss, whereas it is administered orally for the treatment and management of a medical condition, i.e., alopecia. AIM/OBJECTIVE The present review aimed to provide an in-depth study on hair loss and its management using CBD and its associated mechanisms. METHODS Electronic databases, such as ScienceDirect, Google Scholar, PubMed, Wiley, Springer, and Scopus, were thoroughly searched for information about how CBD is used, how it works, and what role it plays in treating alopecia and hair loss. RESULTS This review has highlighted the use of CBD-based hair loss therapy, and described various types of hair loss and their treatments. This review also details the phytocannabinoids and the potential mechanisms of CBD's activity against hair loss and alopecia. CONCLUSION The data obtained from the literature regarding CBD and hair loss provide a scientific basis for CBD use in alopecia. Additionally, a more precise and comprehensive study concerning CBD needs to be carried out at the pre-clinical and clinical levels.

Abstract
Apoptosis is a physiological process that occurs in all cell types of the human body, and it profoundly changes the fate of hair by affecting hair follicle cells. This review outlines the cellular changes, intrinsic biochemical characteristics, and mechanisms underlying apoptosis and summarizes the hair follicle life cycle, including development, cycle stages, and corresponding cellular changes. Finally, the relationship between apoptosis and the hair cycle is discussed and the significance of apoptosis in hair loss conditions and drug treatments is highlighted. Apoptosis induces cellular changes and exhibits distinctive properties through intricate signaling pathways. Hair follicles undergo cyclic periods of growth, regression, and dormancy. Apoptosis is closely correlated with the regression phase by triggering hair follicle cell death and shedding. Regulation of apoptosis in hair follicles plays an essential role in hair loss due to maladies and drug treatments. Mitigating apoptosis can enhance hair growth and minimize hair loss. A comprehensive understanding of the correlation between apoptosis and the hair cycle can facilitate the development of novel treatments to prevent hair loss and stimulate hair regeneration.

Abstract
Background Hair loss is a common condition with significant impact globally, yet its treatment efficacy and safety remain debated. Botulinum toxin A (BoNT-A) has emerged as a potential therapeutic option, but a comprehensive review on this topic is lacking. Objective This review critically evaluates the current evidence on BoNT-A for hair loss treatment, highlighting the gaps in previous reviews and providing a comprehensive analysis of its efficacy, safety, and future prospects. Methods A systematic search of electronic databases identified relevant studies published up to September 2022. Results Prior reviews primarily focused on androgenetic alopecia and lacked the evaluation of other alopecia types and underlying mechanisms. Our review addresses this gap, incorporating a broader spectrum of hair loss conditions. Mechanisms of BoNT-A in hair growth modulation, potential side effects, and future research directions are discussed. Conclusion This review adds to the existing body of knowledge by providing a comprehensive evaluation of BoNT-A in hair loss treatment. The findings will serve as a foundation for further research and guide clinicians in making informed decisions, ultimately improving the outcomes and quality of life for individuals suffering from hair loss.

Abstract
Mesotherapy is a technique by which lower doses of therapeutic agents and bioactive substances are administered by intradermal injections to the skin. Through intradermal injections, mesotherapy can increase the residence time of therapeutic agents in the affected area, thus allowing for the use of lower doses and longer intervals between sessions which may in turn improve the treatment outcome and patient compliance. This systematic review aims to summarize the current literature that evaluates the efficacy of this technique for the treatment of hair loss and provides an overview of the results observed. Of the 416 records identified, 27 articles met the inclusion criteria. To date, mesotherapy using 6 classes of agents and their combinations have been studied; this includes dutasteride, minoxidil, growth factors or autologous suspension, botulinum toxin A, stem cells, and mesh solutions/multivitamins. While several studies report statistically significant improvements in hair growth after treatment, there is currently a lack of standardized regimens. The emergence of adverse effects after mesotherapy has been reported. Further large-scale and controlled clinical trials are warranted to evaluate the utility of mesotherapy for hair loss disorders.

Abstract
There is a high demand for an optimal drug delivery system to treat androgenetic alopecia. Topical application of ISX9, which is a neurogenesis inducer, has been found to stimulate hair follicle (HF) regrowth by upregulating the Wnt/β-catenin signaling pathway, an essential pathway involved in initiating HF growth and development. In the present study, a temperature-sensitive, biopolymer-based, biocompatible, and eco-friendly drug-delivery system was synthesized. This system comprised chitosan-grafted poly(glycidyl methacrylate-co-N-isopropyl acrylamide) (Poly(GMA-co-NIPAAm)@CS-PGNCS) as the shell component and PF127 as the core polymer. The hydrophobic nature of the PF127 block copolymer efficiently dissolved the partially water-soluble drug, ISX9, and the thermos-responsive shell polymer effectively released the drug at a definite skin temperature. The optimized spherical nanoparticles demonstrated the lowest critical solution temperature (LCST) at 32 ± 2 °C with a diameter of 100-250 nm, which delivered encapsulated ISX9 with greater precision than topical ISX9. In a series of in vivo experiments, we demonstrated that ISX9-coated TBNPs upregulated the expression of β-catenin, active β-catenin, Wnt target genes, stemness marker genes, proliferating cell nuclear antigen, HF stem cell markers, and HF markers including VEGF, TGF, and IGF-1 more effectively than topical ISX9. These results suggest that TBNPs could be employed as a platform for effective transdermal delivery of various hydrophobic drugs.

Abstract
AIM To achieve international expert consensus and give recommendations on best practices in hair transplantation surgery, focusing on pre- and post-transplantation care. METHODS A modified Delphi method was used to reach consensus. An international scientific committee developed an 81-statement questionnaire. A panel of 38 experts in hair transplantation from 17 countries across 4 continents assessed the questionnaire. RESULTS Two consensus rounds were carried out, with 59 out of 81 statements (73%) reaching consensus. Expert recommendations emphasize the correct selection of candidates for hair transplantation and the need for patients to have received adequate medical treatment for alopecia before transplant. Comorbidities should be assessed and considered while planning surgery, and an individualized plan for perioperative care should be drawn up before transplant. Certain medications associated with increased risk of bleeding should be withdrawn before surgery. Specific recommendations for post-transplantation care are given. After transplantation, patients should gradually resume their normal haircare regimen. Close follow-up should be carried out during the first year after transplant. CONCLUSIONS This study presents numerous consensus-based recommendations on general aspects of hair transplantation, including candidate selection, medical therapy prior to transplantation, anesthesia, and resuming haircare after transplantation.

Abstract
BACKGROUND The aim of this study was to investigate the serum level of uric acid (UA) in male patients with androgenetic alopecia (AGA) and to compare the level with that of men without AGA. In addition, the comparison of the serum level of uric acid (UA) before and after treatment with finasteride was performed. METHOD A total of 120 male patients with AGA and 120 males without AGA were enrolled in this prospective study. Patients with AGA were randomized into two groups: 60 patients were given 1 mg finasteride orally every day for 6 months, and 60 patients were given placebo. Serum UA level was detected at the first visit and after the 6-month treatment by colorimetric analysis. RESULTS Before treatment, the mean serum UA level in patients with AGA was higher than that in the control group (401.52±83.27 umol/L vs 362.67±60.88 umol/L, P<0.050), and a higher proportion of hyperuricemia was found in patients with AGA (2 9.17% vs 15.00%, P<0.050). After treatment, the mean serum UA level in the finasteride group decreased significantly, from 405.87±87.12 umol/L to 381.84±82.50 umol/L (P<0.050), and from 397.17±79.73 to 394.18±78.09 umol/L in the placebo group (P = 0.370). Patients with AGA with hyperuricemia had a higher BMI (25.38±3.43 kg/m2) when compared to the patients without hyperuricemia (23.88±2.64 kg/m2). For every unit of BMI increase in patients with AGA, the risk of hyperuricemia increased by 30.5% (P = 0.030). Furthermore, the levels of UA were different in the finasteride group before and after treatment (P = 0.049, 95%CI, 0.080, 47.970). CONCLUSIONS We found that AGA has a relationship with hyperuricemia, and the level of serum UA can decrease with the treatment of finasteride.

Abstract
Androgenetic alopecia (AGA) is a widespread type of hair loss that affects both males and females. Advanced age and family history of AGA are well-established risk factors for developing AGA. The second to fourth digit ratio (2D:4D) is the ratio between the length of the index and ring fingers. This ratio has been utilized as a predictor for multiple hyperandrogenism-related medical conditions. More recently, 2D:4D was investigated as a predictor for AGA. This article aims to investigate the evidence supporting the use of 2D:4D as a predictor of AGA, and address areas of future research.

Abstract
RATIONALE Androgenic alopecia (AGA) is a prevalent condition with progressive miniaturization of hair follicles. Currently, reliable treatments have remained limited, and complementary medications for AGA are still being investigated. Traditional Chinese medicine formulas have conspicuous advantages in the treatment of AGA with good development prospects. Zimmer aqueous spray (ZAS) is a water spray containing Zimmer herbal extract powder (ZMWP), which consists of Ligustri lucidi Fructus, Ecliptae Herba, Fallopia multiflora (Thunb.) Harald. and Polygonatum sibiricum Delar. ex Redoute, etc. ZMWP is an active ingredient in the prevention of hair loss. Our aim is to provide evidence for the effectiveness of ZAS in the treatment of AGA. PATIENT CONCERNS A 41-year-old man had suffered from hair loss for 8 years. INTERVENTIONS The patient with moderate AGA received 3 to 4 mL ZAS daily or every other day for 3 months. OUTCOMES The hair density obviously increased after 3 months of therapy. The improvement of hair diameter, vellus hair rate, and 1 hair pilosebaceous unit rate were observed with a trichoscopy and quantitatively analyzed. Besides, honeycomb pigment pattern mitigated and arborized red lines. LESSONS The results suggested that ZMWP might have the capability of improving hair growth and attenuating AGA, which can be a promising alternative treatment of AGA.

Saudi Pharm J 2023; 31:101734. [PMID: 37649675 PMCID: PMC10462889 DOI: 10.1016/j.jsps.2023.101734] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 07/30/2023] [Indexed: 09/01/2023] Open
Abstract
Cetirizine hydrochloride (CTZ), a second-generation anti-histaminic drug, has been recently explored for its effectiveness in the treatment of alopecia. Niosomes are surfactant-based nanovesicular systems that have promising applications in both topical and transdermal drug delivery. The aim of this study was to design topical CTZ niosomes for management of alopecia. Thin film hydration technique was implemented for the fabrication of CTZ niosomes. The niosomes were examined for vesicle size, surface charge, and entrapment efficiency. The optimized niosomal formulation was incorporated into a hydrogel base (HPMC) and explored for physical characteristics, ex vivo permeation, and in vivo dermato-kinetic study. The optimized CTZ-loaded niosomal formulation showed an average size of 403.4 ± 15.6 nm, zeta potential of - 12.9 ± 1.7 mV, and entrapment efficiency percentage of 52.8 ± 1.9%. Compared to plain drug solution, entrapment of CTZ within niosomes significantly prolonged in vitro drug release up to 12 h. Most importantly, ex-vivo skin deposition studies and in vivo dermato-kinetic studies verified superior skin deposition/retention of CTZ from CTZ-loaded niosomal gels, compared to plain CTZ gel. CTZ-loaded niosomal gel permitted higher drug deposition percentage (19.2 ± 1.9%) and skin retention (AUC0-10h 1124.5 ± 87.9 μg/mL.h) of CTZ, compared to 7.52 ± 0.7% and 646.2 ± 44.6 μg/mL.h for plain CTZ gel, respectively. Collectively, niosomes might represent a promising carrier for the cutaneous delivery of cetirizine for the topical management of alopecia.

Abstract
BACKGROUND Androgenetic alopecia (AGA) is one of the most common hair loss diseases worldwide. However, current treatments including medicine, surgery, and stem cells are limited for various reasons. Cell-free fat extract (CEFFE), contains various cell factors, may have potential abilities in treating AGA. This study aims to evaluate the safety, effectiveness and the underlying mechanism of CEFFE in treating AGA. METHODS Sex hormone evaluation, immunogenicity assay and genotoxicity assay were conducted for CEFFE. In vivo study, male C57BL/6 mice were injected subcutaneously with dihydrotestosterone (DHT) and were treated with different concentration of CEFFE for 18 days (five groups and n = 12 in each group: Control, Model, CEFFELow, CEFFEMiddle, CEFFEHigh). Anagen entry rate and hair coverage percentage were analyzed through continuously taken gross photographs. The angiogenesis and proliferation of hair follicle cells were evaluated by hematoxylin-eosin, anti-CD31, and anti-Ki67 staining. In vitro study, dermal papilla cells (DPCs) were incubated with different concentrations of CEFFE, DHT, or CEFFE + DHT, followed by CCK-8 assay and flow cytometry to evaluate cell proliferation cycle and apoptosis. The intracellular DHT level were assessed by enzyme-linked immunosorbent assay. The expression of 5α-reductase type II, 3α-hydroxysteroid dehydrogenase and androgen receptor were assessed through reverse transcription-quantitative polymerase chain reaction (RT-qPCR) or/and western blot. RESULTS In CEFFE-treated mice, an increase in the anagen entry rate and hair coverage percentage was observed. The number of CD31-positive capillaries and Ki67-positive cells were increased, suggesting that CEFFE promoted the proliferation of DPCs, modulated the cell cycle arrest, inhibited apoptosis caused by DHT, reduced the intracellular concentration of DHT in DPCs, and downregulated the expression of AR. CONCLUSIONS CEFFE is a novel and effective treatment option for AGA through producing an increased hair follicle density and hair growth rate. The proposed mechanisms are through the DHT/AR pathway regulation and regional angiogenesis ability.

Abstract
Many people suffer from hair loss and abnormal skin pigmentation, highlighting the need for simple assays to support drug discovery research. Current assays have various limitations, such as being in vitro only, not sensitive enough, or unquantifiable. We took advantage of the bilateral symmetry and large size of mouse whisker follicles to develop a novel in vivo assay called "whisker follicle microinjection assay". In this assay, we plucked mouse whiskers and then injected molecules directly into one side of the whisker follicles using microneedles that were a similar size to the whiskers, and we injected solvent on the other side as a control. Once the whiskers grew out again, we quantitatively measured their length and color intensity to evaluate the effects of the molecules on hair growth and coloring. Several chemicals and proteins were used to test this assay. The chemicals minoxidil and ruxolitinib, as well as the protein RSPO1, promoted hair growth. The effect of the clinical drug minoxidil could be detected at a concentration as low as 0.001%. The chemical deoxyarbutin inhibited melanin production. The protein Nbl1 was identified as a novel hair-growth inhibitor. In conclusion, we successfully established a sensitive and quantitative in vivo assay to evaluate the effects of chemicals and proteins on hair growth and coloring and identified a novel regulator by using this assay. This whisker follicle microinjection assay will be useful when investigating protein functions and when developing drugs to treat hair loss and abnormal skin pigmentation.

Abstract
Androgenetic alopecia (AGA) is the most common cause of hair loss in men and women. Traditionally, topical minoxidil and oral finasteride have been the standard of care yielding mixed results. New treatments such as Low-Level Laser Therapy (LLLT), microneedling, platelet-rich plasma (PRP), and others have been extensively studied in the literature, and the purpose of this review is to provide a comprehensive discussion of the latest treatment methods and their efficacy in treating AGA. Novel therapies such as oral minoxidil, topical finasteride, topical spironolactone, botulinum toxin, and stem cell therapy offer interesting alternatives to standard of care therapies for patients. In this review, we present data from recent studies on the clinical efficacy of these treatments. Furthermore, as new treatments have emerged, clinicians have tested combination therapies to assess whether there may be a synergistic relationship between multiple modalities. While there has been a great increase in the treatments available for AGA, the quality of evidence varies greatly and there is still a great need for randomized double blinded clinical trials to adequately assess the clinical efficacy of some treatments. While PRP and LLLT have demonstrated encouraging results, standardized treatment protocols are needed to adequately inform clinicians on how to use such therapies. Given the abundance of new therapeutic options, clinicians and patients must weigh the benefits and risks of each treatment option for AGA.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Allium macrostemon Bunge (AMB), a widely distributed wild garlic plant, possesses a variety of health-promoting properties. Androgenetic alopecia (AGA) is a common disorder that affects quality of life. AIM OF THE STUDY We sought to investigate whether AMB stimulates hair regrowth in AGA mouse model, and clarify the underlying molecular mechanisms. MATERIALS AND METHODS The chemical constituents of AMB water extract were identified by ultra-high performance liquid chromatography-quadrupole-time of flight-mass spectrometry (UPLC-Q/TOF-MS) analysis. Cell viability assay and Ki-67 immunostaining were undertaken to evaluate the impacts of AMB on human hair dermal papilla cell (HDPC) proliferation. Wound-healing assay was undertaken to assess cell migration. Flow cytometry and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay were performed to examine cell apoptosis. Western blotting, real-time reverse transcription-quantitative polymerase chain reaction (RT-qPCR), and immunostaining assays were undertaken to determine the impacts of AMB on Wnt/β-catenin signaling and growth factors expression in HDPC cells. AGA mouse model was induced by testosterone treatment. The effects of AMB on hair regeneration in AGA mice were demonstrated by hair growth measuring and histological scoring. The levels of β-catenin, p-GSK-3β, and Cyclin D1 in dorsal skin were measured. RESULTS AMB promoted proliferation and migration, as well as the expression of growth factors in cultured HDPC cells. Meanwhile, AMB restrained apoptosis of HDPC cells by increasing the ratio of anti-apoptotic Bcl-2/pro-apoptotic Bax. Besides, AMB activated Wnt/β-catenin signaling and thereby enhancing growth factors expression as well as proliferation of HDPC cells, which was abolished by Wnt signaling inhibitor ICG-001. In addition, an increase of hair shaft elongation was observed in mice suffering from testosterone-induced AGA upon the treatment of AMB extract (1% and 3%). Consistent with the in vitro assays, AMB upregulated the Wnt/β-catenin signaling molecules in dorsal skin of AGA mice. CONCLUSION This study demonstrated that AMB promoted HDPC cell proliferation and stimulated hair regrowth in AGA mice. Wnt/β-catenin signaling activation, which induced production of growth factors in hair follicles and, eventually, contributed to the influence of AMB on the hair regrowth. Our findings may contribute to effective utilization of AMB in alopecia treatment.

Abstract
Androgenetic alopecia (AGA), also known as male pattern hair loss (MPHL) or female pattern hair loss (FPHL), is the most common form of alopecia worldwide, and arises from an excessive response to androgens. AGA presents itself in a characteristic distribution unique to both sexes. Despite its prevalence, AGA can be quite challenging to treat. The condition is chronic in nature and stems from an interplay of genetic and environmental factors. There are only two US Food and Drug Administration (FDA)-approved drugs for the condition: topical minoxidil and oral finasteride. However, numerous non-FDA-approved treatments have been shown to be effective in treating AGA in various studies. Some of these treatments are relatively new and still to be explored, thus emphasizing the need for an updated review of the literature. In this comprehensive review, we discuss the evaluation of AGA and the mechanisms of action, costs, efficacies, and safety profiles of existing, alternative, and upcoming therapeutics for this widespread condition.

Abstract
The strategy in this work was loading Melatonin (MEL), the powerful antioxidant photosensitive molecule, in novel Pickering emulsions (PEs) stabilized by chitosan-dextran sulphate nanoparticles (CS-DS NPs) and enhanced by lecithin, for treatment of androgenic alopecia (AGA). Biodegradable CS-DS NPs dispersion was prepared by polyelectrolyte complexation and optimized for PEs stabilization. PEs were characterized for droplet size, zeta potential, morphology, photostability and antioxidant activity. Ex-vivo permeation study through rat full thickness skin was conducted with optimized formula. Differential tape stripping trailed by cyanoacrylate skin surface biopsy was executed, for quantifying MEL in skin compartments and hair follicles. In-vivo evaluation of MEL PE hair growth activity was performed on testosterone induced AGA rat model. Visual inspection followed by anagen to telogen phase ratio (A/T) and histopathological examinations were conducted and compared with marketed 5% minoxidil spray "Rogaine ®". Data showed that PE improved MEL antioxidant activity and photostability. Ex-vivo results displayed MEL PE high follicular deposition. In-vivo study demonstrated that MEL PE treated testosterone induced AGA rat group, restored hair loss and produced maximum hair regeneration along with prolonged anagen phase amongst tested groups. The histopathological examination revealed that MEL PE prolonged anagen stage, increased follicular density and A/T ratio by 1.5-fold. The results suggested that lecithin-enhanced PE stabilized by CS-DS NPs was found to be an effective approach to enhance photostability, antioxidant activity and follicular delivery of MEL. Thus, MEL-loaded PE could be a promising competitor to commercially marketed Minoxidil for treatment of AGA.

Abstract
Pathological hair loss (also known as alopecia) and shortage of hair follicle (HF) donors have posed an urgent requirement for HF regeneration. With the revelation of mechanisms in tissue engineering, the proliferation of HFs in vitro has achieved more promising trust for the treatments of alopecia and other skin impairments. Theoretically, HF organoids have great potential to develop into native HFs and attachments such as sweat glands after transplantation. However, since the rich extracellular matrix (ECM) deficiency, the induction characteristics of skin-derived cells gradually fade away along with their trichogenic capacity after continuous cell passaging in vitro. Therefore, ECM-mimicking support is an essential prelude before HF transplantation is implemented. This review summarizes the status of providing various epidermal and dermal cells with a three-dimensional (3D) scaffold to support the cell homeostasis and better mimic in vivo environments for the sake of HF regeneration. HF-relevant cells including dermal papilla cells (DPCs), hair follicle stem cells (HFSCs), and mesenchymal stem cells (MSCs) are able to be induced to form HF organoids in the vitro culture system. The niche microenvironment simulated by different forms of biomaterial scaffold can offer the cells a network of ordered growth environment to alleviate inductivity loss and promote the expression of functional proteins. The scaffolds often play the role of ECM substrates and bring about epithelial-mesenchymal interaction (EMI) through coculture to ensure the functional preservation of HF cells during in vitro passage. Functional HF organoids can be formed either before or after transplantation into the dermis layer. Here, we review and emphasize the importance of 3D culture in HF regeneration in vitro. Finally, the latest progress in treatment trials and critical analysis of the properties and benefits of different emerging biomaterials for HF regeneration along with the main challenges and prospects of HF regenerative approaches are discussed.

Abstract
Alopecia and gray hair are common hair abnormalities affecting physical appearance and causing psychological problems. Chemical treatments partially restore hair disorders but have distressing side effects. Bioactive plant compounds constitute promising sources of potential medicinal substances instead of chemical agents, producing high side effects. In this study, we focused on the waste of local rice cultivars: Bue Bang 3 CMU (BB3CMU) and Bue Bang 4 CMU (BB4CMU) from the north of Thailand. The rice bran oil (RBO), defatted rice bran extract (DFRB), and rice husk (H) were determined for in vitro hair revitalization in melanin production, nitric oxide (NO) secretion, and steroid 5α-reductase inhibition. The results indicated that BB4CMU-RBO with high contents of iron, zinc, and free fatty acids showed a comparable induction of melanin production on melanocytes (130.18 ± 9.13% of control) to the standard drug theophylline with no significant difference (p > 0.05). This promising melanin induction could be related to activating the NO secretion pathway, with the NO secretion level at 1.43 ± 0.05 µM. In addition, BB4CMU-RBO illustrated a significant inhibitory effect on both steroid 5α-reductase genes (SRD5A) type 1 and type 2, which relates to its primary source of tocopherols. Hence, rice bran oil from the Thai rice variety BB4CMU could be applied as a promising hair revitalizing candidate, from natural resources, to help promote hair growth and re-pigmentation effects.

Abstract
Androgenetic alopecia (AGA) is a transracial and cross-gender disease worldwide with a youth-oriented tendency, but it lacks effective treatment. The binding of androgen receptor (AR) and androgen plays an essential role in the occurrence and progression of AGA. Herein, novel proteolysis targeting chimera degrader of AR (AR-PROTAC) is synthesized and integrated with dissolving microneedles (PROTAC-MNs) to achieve AR destruction in hair follicles for AGA treatment. The PROTAC-MNs possess adequate mechanical capabilities for precise AR-PROTAC delivery into the hair follicle-residing regions for AR degradation. After applying only once topically, the PROTAC-MNs achieve an accelerated onset of hair regeneration as compared to the daily application of the first-line topical drug minoxidil. Intriguingly, PROTAC-MNs via single administration still realize superior hair regeneration in AGA recrudescence, which is the major drawback of minoxidil in clinical practice. With the degradation of AR, the PROTAC-MNs successfully regulate the signaling cascade related to hair growth and activate hair follicle stem cells. Furthermore, the PROTAC-MNs do not cause systemic toxicity or androgen deficiency-related chaos in vivo. Collectively, these AR-degrading dissolving microneedles with long-lasting efficacy, one-step administration, and high biocompatibility provide a great therapeutic potential for AGA treatment.

Abstract
Prostaglandin metabolism is involved in the regulation of the periodic process of hair follicles. Preliminary research data reported that prostaglandin E2 (PGE2) exhibits potential in hair growth. However, the relevant evidence is still insufficient. Herein, we prepared a PGE2 matrix by conjugating PGE2 with collagen via crosslinkers to avoid rapid degradation of PGE2 molecules in vivo. First, we measured the physical properties of the PGE2 matrix. A mouse model of hair loss was established, and PGE2 matrix subcutaneous injection was applied to evaluate hair growth. Under different treatments with the PGE2 matrix, the morphology of hair follicles, the dynamic expression of hair follicle stem cell markers and key regulators in the hair growth cycle were explored. Our data revealed that the PGE2 matrix increased the proportion of developing hair follicles at the early growth stage. Improvements in hair follicle stem cells, such as Sox9+ and Lgr5+ cells, have also been confirmed as therapeutic effects of PGE2 to stimulate hair follicle growth. Our study indicated that PGE2 exhibits effective roles in hair development during anagen. Furthermore, the results also highlight the potential of the PGE2 delivery system as a novel therapeutic strategy for the treatment of hair disorders in the future.

Insights into male androgenetic alopecia using comparative transcriptome profiling: hypoxia-inducible factor-1 and Wnt/β-catenin signalling pathways. Br J Dermatol 2022; 187:936-947. [PMID: 35862273 PMCID: PMC10087000 DOI: 10.1111/bjd.21783] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Revised: 04/13/2022] [Accepted: 07/12/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND The key pathophysiological changes in androgenetic alopecia (AGA) are limited to hair follicles (HFs) in frontal and vertex regions, sparing the occipital region. OBJECTIVES To identify biological differences among HF subpopulations. METHODS Paired vertex and occipital HFs from 10 male donors with AGA were collected for RNA sequencing assay. Furthermore, HF and cell experiments were conducted on the identified key genes to reveal their roles in AGA. RESULTS Transcriptome profiles revealed that 506 mRNAs, 55 microRNAs and 127 long noncoding RNAs were differentially expressed in the AGA vertex HFs. Pathway analysis of mRNAs and microRNAs revealed involvement of the hypoxia-inducible factor (HIF)-1, Wnt/β-catenin, and focal adhesion pathways. Differential expression of HIF-1 prolyl hydroxylase enzymes (EGLN1, EGLN3) and Wnt/β-catenin pathway inhibitors (SERPINF1, SFRP2) was experimentally validated. In vitro studies revealed that reduction of EGLN1, EGLN3, SERPINF1 and SFRP2 stimulated proliferation of dermal papilla cells. Ex vivo HF studies showed that downregulation of EGLN1, EGLN3 and SERPINF1 promoted HF growth, postponed HF catagen transition, and prolonged the anagen stage, suggesting that these genes may be potentially utilized as therapeutic targets for AGA. CONCLUSIONS We characterized key transcriptome changes in male AGA HFs, and found that HIF-1 pathway-related genes (EGLN1, EGLN3) and Wnt pathway inhibitors (SERPINF1, SFRP2) may play important roles in AGA. What is already known about this topic? Multiple differentially expressed genes and signalling pathways have been found between hair follicles (HFs) in the balding area (frontal and vertex regions) and nonbalding area (occipital region) of individuals with androgenetic alopecia (AGA). A whole-transcriptome atlas of the vertex and occipital region is lacking. What does this study add? We identified a number of differentially expressed genes and pathways between balding vertex and nonbalding occipital AGA HFs by using whole-transcriptome analyses. We identified pathways not previously reported in AGA, such as the hypoxia-inducible factor (HIF)-1 signalling pathway. We verified that HIF-1 pathway-related genes (EGLN1, EGLN3) and Wnt pathway inhibitors (PEDF, SFRP2) played important roles in dermal papilla cell activity, hair growth and the hair cycle. What is the translational message? The EGLN1, EGLN3, SERPINF1 and SFRP2 genes may be potentially utilized as therapeutic targets for AGA.

Abstract
Hair loss in elderly patients is a common complaint. It can be related to different conditions that affect patients' quality of life and represents a challenge for dermatologists. It affects both men and women during the aging process with an estimated percentage of balding after 65 years of age of 53% and 37%, respectively. Androgenetic alopecia, frontal fibrosing alopecia, senile alopecia, and erosive pustular dermatosis of the scalp are the hair diseases most frequently described in this age group. The objective of this review is to summarize the current knowledge about alopecia affecting elderly patients, differentiating between chronological hair aging signs and pathological changes, to help clinicians, offer an adequate management of these disorders to their patients.

Abstract
BACKGROUND Female Pattern Hair Loss (FPHL) is one of the most common types of hair loss in women. It is characterized by progressive follicular miniaturization leading to diffuse hair thinning over the midfrontal scalp with a negative impact on quality of life. Pharmacological treatments are commonly used, and hair follicle transplantation is an option for those cases with adequate donor area. Minimally invasive procedures, such as microneedling, mesotherapy, microinfusion of drugs into the scalp with tattoo machines (MMP®), and platelet-rich plasma (PRP) have been reported as adjuvant treatments. AIMS This study aims to summarize and discuss the efficacy of minimally invasive procedures described for the management of FPHL. METHODS Published articles indexed on the Pubmed database and Scopus that described minimally invasive procedures for the management of FPHL in humans were considered. Citations were reviewed and added for completeness. The search was for articles in English only. After excluding duplicate titles, 23 relevant articles were considered. CONCLUSION Minimally invasive procedures are promising options and may play a role in FPHL treatment. They can be used as adjunctive therapy for FPHL, in case of poor response to clinical therapy, or when patients prefer other care than the standard. We reinforce that these methods should be performed by an experienced medical professional following strict aseptic techniques. However, microneedling, mesotherapy, MMP, and PRP lack standardization and are supported by a low level of evidence yet. For the future, larger randomized clinical trials are essential to determine the efficacy and optimal protocols for these treatments.

Abstract
BACKGROUND Cetirizine, a widely used agent for allergic disorders, has recently been topically used for treating androgenetic alopecia (AGA). We aimed to summarize the current evidence regarding the effectiveness and safety of topical cetirizine for treating AGA. METHODS We searched Ovid MEDLINE, Embase, and Cochrane Central Register of Controlled Trials. We included both randomized controlled trials (RCTs) and non-randomized clinical trials. FINDINGS We initially identified 102 records, of which, we included two RCTs and one non-randomized clinical trial, which were of moderate-to-high risk of bias. All included trials used 1% topical cetirizine as the intervention with various regimens. Topical cetirizine was likely to be more effective than a placebo for treating AGA. In comparison with topical minoxidil, topical cetirizine appears to be less effective for improving total and vellus hair density, but it might have a longer-lasting effect. Further, cetirizine might be as effective as minoxidil in improving hair diameter. CONCLUSION One percent topical cetirizine may serve as a choice for treating AGA, especially for patients with a negative response to topical minoxidil. In order to fully understand the role of topical cetirizine for AGA, additional well-designed RCTs are needed.

[PMID: 36015077 PMCID: PMC9412580 DOI: 10.3390/ph15080930] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 07/23/2022] [Accepted: 07/25/2022] [Indexed: 02/06/2023] Open
Abstract
Pumpkin seed oil (PSO)-loaded niosomes were prepared from Tween 20 and cholesterol by ethanol injection. Confocal microscopy showed better skin permeation and hair follicle accumulation of the niosomes compared to the PSO solution. The PSO-loaded niosomes inhibited 5α-reductase activity in DU-145 cells and hindered IL-6 activity in RAW 264.7 cells. These effects indicated the great potential of PSO-loaded niosomes to reduce hair loss. The hair scalp serum with PSO-loaded niosomes did not show irritation to reconstructed human skin. This formulation presented a significant decrease in the percentage of fallen hairs by 44.42% in the in vivo 60-second hair count experiment and a significant increase in the anagen to telogen (A/T) ratio (1.4-fold) in the TrichoScan® evaluation after 8 weeks of treatment compared to the initial conditions, indicating the promising efficacy of PSO-loaded niosomes as a natural alternative for anti-hair loss therapy.

Abstract
Alopecia or hair loss is a widespread issue that has significant effects on personal well-being for both genders nationally and internationally. In addition, alopecia causes extreme emotional stress and negatively impacts the psychological health and self-esteem of cancer patients suffering from chemotherapy-induced alopecia. Unfortunately, available synthetic medications are costly, invasive, or have extreme adverse effects. On the contrary, natural and herbal hair loss products are widely available in the local and international markets in variable pharmaceutical forms with different mechanisms of action, namely, androgen antagonists, nutritional supplements, vasodilators, and 5α-reductase inhibitors or dihydrotestosterone blockers. Thus, it is of great importance to encourage researchers to investigate these natural alternatives that can act as potent therapeutic agents having diverse mechanisms of action as well as limited side effects. Currently, natural remedies are considered a fast-rising pharmaceutical segment with demand from a wide range of consumers. In this study, we present a review of reported herbal remedies and herb combinations recommended for hair loss and their mode of action, along with an overview of available market products and formulations, their composition, and declared effects. In addition, a general outline of the different forms of alopecia, its causes, and recommended treatments are mentioned as well. This was all done with the aim of assisting further studies with developing standardized natural formulations for alopecia as many were found to lack standardization of their bioactive ingredients and efficiency confirmation.

Unrevealing the Potential of Sansevieria trifasciata Prain Fraction for the Treatment of Androgenetic Alopecia by Inhibiting Androgen Receptors Based on LC-MS/MS Analysis, and In-Silico Studies. Molecules 2022; 27:molecules27144358. [PMID: 35889232 PMCID: PMC9318048 DOI: 10.3390/molecules27144358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 06/24/2022] [Accepted: 07/05/2022] [Indexed: 11/17/2022] Open
Abstract
Androgenetic Alopecia (AGA) occurs due to over-response to androgens causing severe hair loss on the scalp, and requires the development of new and efficient drugs to treat this condition. This study explores and identifies secondary metabolites from Sansevieriatrifasciata Prain using the LC-MS/MS and in-silico method. The inhibitory activity of bioactive compounds from S. trifasciata Prain against androgen receptors (PDB ID: 4K7A) was evaluated molecularly using docking and dynamics studies by comparing their binding energies, interactions, and stability with minoxidil. The results of the LC-MS/MS analysis identified Methyl pyrophaeophorbide A (1), Oliveramine (2), (2S)-3′, 4′-Methylenedioxy-5, 7-dimethoxyflavane (3), 1-Acetyl-β-carboline (4), Digiprolactone (5), Trichosanic acid (6) and Methyl gallate (7) from the leaves subfraction of this plant. Three alkaloid compounds (compounds 1, 3, and 4), and one flavonoid (compound 2), had lower docking scores of −7.0, −5.8, −5.2, and −6.3 kcal/mol, respectively. The prediction of binding energy using the MM-PBSA approach ensured that the potency of the four compounds was better than minoxidil, with energies of −66.13, −59.36, −40.39, and −40.25 kJ/mol for compounds 1, 3, 2, and 4, respectively. The dynamics simulation shows the stability of compound 1 based on the trajectory analysis for the 100 ns simulation. This research succeeded in identifying the compound and assessing the anti-alopecia activity of Sansevieria trifasciata Prain. Seven compounds were identified as new compounds never reported in Sansevieria trifasciata Prain. Four compounds were predicted to have better anti-alopecia activity than minoxidil in inhibiting androgen receptors through an in silico approach.

Abstract
Androgenetic alopecia (“AGA”) is the most prevalent type of progressive hair loss, causing tremendous psychological and social stress in patients. However, AGA treatment remains limited in scope. The pathogenesis of androgenetic alopecia is not completely understood but is known to involve a hair follicle miniaturization process in which terminal hair is transformed into thinner, softer vellus-like hair. This process is related to the dysregulation of the Wnt/β-catenin signaling pathway, which causes premature termination of the anagen growth phase in hair follicles. Historically used for wound healing, platelet rich plasma (“PRP”) has recently been at the forefront of potential AGA treatment. PRP is an autologous preparation of plasma that contains a high number of platelets and their associated growth factors such as EGF, IGF-1, and VEGF. These factors are known to individually play important roles in regulating hair follicle growth. However, the clinical effectiveness of PRP is often difficult to characterize and summarize as there are wide variabilities in the PRP preparation and administration protocols with no consensus on which protocol provides the best results. This study follows the previous review from our group in 2018 by Cervantes et al. to analyze and discuss recent clinical trials using PRP for the treatment of AGA. In contrast to our previous publication, we include recent clinical trials that assessed PRP in combination or in direct comparison with standard of care procedures for AGA such as topical minoxidil and/or oral finasteride. Overall, this study aims to provide an in-depth analysis of PRP in the treatment of AGA based on the evaluation of 17 recent clinical trials published between 2018 and October 2021. By closely examining the methodologies of each clinical trial included in our study, we additionally aim to provide an overall consensus on how PRP can be best utilized for the treatment of AGA.

Abstract
Human hair dermal papillary (DP) cells comprising mesenchymal stem cells in hair follicles contribute critically to hair growth and cycle regulation. The transition of hair follicles from telogen to anagen phase is the key to regulating hair growth, which relies heavily on the activation of DP cells. In this paper, we suggested exosomes derived from bovine colostrum (milk exosomes, Milk-exo) as a new effective non-surgical therapy for hair loss. Results showed that Milk-exo promoted the proliferation of hair DP cells and rescued dihydrotestosterone (DHT, androgen hormones)-induced arrest of follicle development. Milk-exo also induced dorsal hair re-growth in mice at the level comparable to minoxidil treatment, without associated adverse effects such as skin rashes. Our data demonstrated that Milk-exo accelerated the hair cycle transition from telogen to anagen phase by activating the Wnt/β-catenin pathway. Interestingly, Milk-exo has been found to stably retain its original properties and efficacy for hair regeneration after freeze-drying and resuspension, which is considered critical to use it as a raw material applied in different types of alopecia medicines and treatments. Overall, this study highlights a great potential of an exosome from colostrum as a therapeutic modality for hair loss.

Abstract
Alopecia or baldness is a common diagnosis in clinical practice. Alopecia can be scarring or non-scarring, diffuse or patchy. The most prevalent type of alopecia is non-scarring alopecia, with the majority of cases being androgenetic alopecia (AGA) or alopecia areata (AA). AGA is traditionally treated with minoxidil and finasteride, while AA is treated with immune modulators; however, both treatments have significant downsides. These drawbacks compel us to explore regenerative therapies that are relatively devoid of adverse effects. A thorough literature review was conducted to explore the existing proven and experimental regenerative treatment modalities in non-scarring alopecia. Multiple treatment options compelled us to classify them into growth factor-rich and stem cell-rich. The growth factor-rich group included platelet-rich plasma, stem cell-conditioned medium, exosomes and placental extract whereas adult stem cells (adipose-derived stem cell-nano fat and stromal vascular fraction; bone marrow stem cell and hair follicle stem cells) and perinatal stem cells (umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs), Wharton jelly-derived MSCs (WJ-MSCs), amniotic fluid-derived MSCs (AF-MSCs), and placental MSCs) were grouped into the stem cell-rich group. Because of its regenerative and proliferative capabilities, MSC lies at the heart of regenerative cellular treatment for hair restoration. A literature review revealed that both adult and perinatal MSCs are successful as a mesotherapy for hair regrowth. However, there is a lack of standardization in terms of preparation, dose, and route of administration. To better understand the source and mode of action of regenerative cellular therapies in hair restoration, we have proposed the "À La Mode Classification". In addition, available evidence-based cellular treatments for hair regrowth have been thoroughly described.

[PMID: 35133683 DOI: 10.1111/ics.12764] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 01/06/2022] [Accepted: 02/07/2022] [Indexed: 12/01/2022]
Abstract
OBJECTIVE Hair loss and greying affect men and women of all ages, often causing psychosocial difficulties. Dickkopf-1 (DKK1), a major hair loss factor secreted from dermal papilla (DP) cells in response to the secretion of dihydrotestosterone (DHT), has been reported to induce and accelerate androgenetic alopecia (AGA). In addition, DKK1 acts as a potent suppressor of melanogenesis and is closely related to hair colour. R-spondin 1 (RSPO1) is a secretory agonist of Wnt signalling known to antagonize the effects of DKK1, including DKK1-mediated hair follicle suppression. In this study, we investigated the effect of watercress extract (WCE) on the secretion of RSPO1 and DKK1 from DP cells as well as its anti-hair loss effect in human hair follicles and patients. METHODS The in vitro secretion of RSPO1 and DKK1 was measured by ELISA. Human hair follicles were collected from the scalp of a female donor and used for ex vivo organ culture to investigate the effects of WCE on human hair loss. Finally, a 6-month human clinical trial was conducted to examine the effect of WCE-containing lotion on hair growth in a male panel. RESULTS WCE significantly upregulated RSPO1 secretion and suppressed DKK1 secretion in a dose-dependent manner, even in the presence of DHT. WCE-treated hair follicles elongated 1.6-fold compared to the control, and the level of RSPO1 production in DP as well as RSPO1 bound to the outer root sheath (ORS) increased. In the clinical trial, the hair lotion containing 2% WCE increased hair thickness and density to improve against hair loss symptoms. CONCLUSION WCE exhibited a strong anti-androgenic effect through its ability to suppress DKK1 secretion and antagonize DKK1 via RSPO1. These findings highlighted the potential use of WCE for the treatment of hair loss. These results also showed that WCE might have an effect on hair colour since DKK1 is a suppressor of melanogenesis.

Abstract
Androgenetic alopecia (AGA), also known as male pattern baldness, is associated with androgen and androgen receptor (AR) signaling; however, the pathogenesis of AGA remains largely unknown. Here, we demonstrate that nuclear localization of androgen receptor is elevated in the dermal papilla (DP) of balding scalp from patients with AGA. Transcriptome analysis identifies microvascular abnormalities in the DP of balding scalp compared to non-balding scalp of AGA patients. We provide further evidence that blood vessels regress in the DP of balding scalp at the early stage of hair follicle miniaturization in AGA development. Consistently, we find that microvascular vessels accumulate around the dermal papilla upon anagen initiation, and angiogenesis is required for hair regeneration in mice. Mechanistically, we show that AR-mediated paracrine signaling, mainly TGF-β signaling, from DP cells induces apoptosis of microvascular endothelial cells in the DP of balding scalp of AGA. These findings define a role of AR-mediated regression of blood vessels in DP in AGA and support the notion that early anti-AR treatment is better than late treatment.

Abstract
Background The most commonly acknowledged non-scarring alopecia are androgenetic alopecia (AGA) and alopecia areata (AA). Previous studies have revealed various risk factors associated with alopecia. However, the relationship between leukocyte telomere length (LTL) and non-scarring alopecia remains unclear. Methods A two-sample Mendelian randomization (MR) analysis was performed to evaluate the causality between genetically predicted LTL and the risk of non-scarring alopecia. MR analyses were performed using the inverse variance-weighted (IVW) method and complemented with other MR methods. Results The summary statistics of the genome-wide association studies (GWAS) for AGA and AA were obtained from the FinnGen biobank, which included 119,185 and 211,428 individuals, respectively. A total of 126 single nucleotide polymorphisms (SNPs) with genome-wide significance were selected as the instrumental variables for LTL. The MR analyses suggested a causal relationship between LTL and AGA, and the risk of AGA increased by 3.19 times as the genetically predicted LTL was shortened by one standard deviation in log transformed form under the IVW method (OR = 4.19, 95% CI = 1.20-14.61, p = 0.024). The other MR methods also demonstrated a similar trend of the effect of LTL on AGA. There was no causal relationship between LTL and AA (p > 0.05). Sensitivity analyses further demonstrated that the current results were less likely to be affected by confounders and bias. Conclusion Our results suggested a potential causal relationship between LTL and AGA, and shortened LTL was associated with an increased risk of AGA.

Abstract
The association of androgenetic alopecia with metabolic syndrome has been investigated in several studies, with conflicting results. We conducted a meta-analysis to quantitatively evaluate the risk grade of metabolic syndrome and the metabolic profile in patients with androgenetic alopecia compared with controls. In total, 19 articles (2,531 participants) satisfied the inclusion criteria. The pooled odds ratio for the prevalence rate of metabolic syndrome between the group with androgenetic alopecia and controls was 3.46 (95% CI 2.38–5.05; p < 0.001). Female sex, early onset, and African ethnicity were associated with an increased risk of metabolic syndrome. Furthermore, patients with androgenetic alopecia had significantly poorer metabolic profiles, such as body mass index, waist circumference, fasting glucose, blood lipids, and blood pressure. It is important for physicians to screen metabolism-related indicators in patients with androgenetic alopecia. More rigorously designed studies and larger sample sizes are required in future studies.

Impaired metabolic effects of metformin in men with early-onset androgenic alopecia. Pharmacol Rep 2021; 74:216-228. [PMID: 34897595 PMCID: PMC8786753 DOI: 10.1007/s43440-021-00347-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2021] [Revised: 11/15/2021] [Accepted: 11/30/2021] [Indexed: 12/31/2022]
Abstract
Background Early-onset androgenic alopecia is considered the phenotypic equivalent of polycystic ovary syndrome in men. The purpose of the current study was to investigate whether the presence of early-onset male-pattern baldness modulates metabolic effects of metformin. Methods This prospective case–control study included 2 groups of men at high risk for type 2 diabetes: 72 individuals with androgenic alopecia (group A) and 75 subjects with normal hair growth (group B). Both groups were matched for age, blood pressure, body mass index, insulin sensitivity and plasma lipids. Glycated hemoglobin, glucose, plasma lipids, indices of insulin sensitivity/resistance, sex hormones, high-sensitivity C-reactive protein (hsCRP) and 25-hydroxyvitamin D were determined before and after metformin treatment (1.7 g daily). Results Twelve-month metformin treatment reduced fat content, waist circumference, glycated hemoglobin, glucose and triglycerides, as well as improved insulin sensitivity. Although observed in both study populations, these effects were more pronounced in group B. Moreover, metformin decreased hsCRP and bioavailable testosterone levels in group B, as well as reduced 25-hydroxyvitamin D concentration in group A. Treatment-induced changes in glucose homeostasis markers correlated with the impact of metformin on hsCRP and 25-hydroxyvitamin D levels. Conclusions Metabolic effects of metformin in males are attenuated if they have coexisting early-onset androgenic alopecia. This finding may be partially explained by differences in severity of low-grade systemic inflammation and vitamin D status. The obtained results, requiring confirmation in large prospective studies, suggest that men with early-onset male-pattern baldness benefit to a lesser degree from metformin treatment than other men at high risk for type 2 diabetes.

Abstract
Objectives To study the association between androgenetic alopecia (AGA) and its severity with psychosocial well-being in male subjects aged 46 years at the population level. Design Cross-sectional study. Setting The Northern Finland Birth Cohort 1966 (NFBC1966). Participants Data were available for 892 male subjects aged 46 years. Interventions Study subjects underwent comprehensive health examinations including a skin evaluation by dermatologists and determination of AGA according to the Norwood classification. They also filled in a questionnaire battery that included previously validated questionnaires: the Hopkins Symptom Checklist-25, the Beck Depression Inventory–II; the Generalised Anxiety Disorder Screener; a 15-dimensional measure of health-related quality of life; a 12-Item General Health Questionnaire. The battery also included questions about self-esteem and sexual health. Main outcome measurements The presence of AGA and its severity, psychosocial well-being. Results AGA was found in 68.5% of subjects, 27.8% of the cases were severe, 33.2% moderate and 39.0% mild. There was no significant association between the presence of AGA or its severity with depression, anxiety, quality of life, self-esteem or sexual symptoms. Those with severe AGA reported lower sexual activity when compared with those without AGA; however, the difference was not statistically significant. Conclusions Middle-aged men with AGA did not differ from men without AGA in terms of psychosocial well-being.
