[PMID: 38006746 PMCID: PMC10709127 DOI: 10.1016/j.jaim.2023.100817] [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: 03/26/2023] [Revised: 08/09/2023] [Accepted: 10/20/2023] [Indexed: 11/27/2023] Open
Abstract
BACKGROUND Alopecia is a dermatological condition affecting genders, negatively impacting their personality and quality of life (QoL). The current approved entities are limited, inconsistently effective, and associated with negative side effects. To alleviate this issue, ayurvedic herbs such as Ashwagandha have being explored. As a result, this study was designed to evaluate the efficacy and safety of Ashwagandha (root extract) topical formulation (serum) on hair health in healthy adults. METHODS In this prospective, double-blind, randomized, placebo controlled, two arm, parallel, comparative study, the effects of topical Ashwagandha on the hair health was evaluated. Healthy adults between 18 and 45 years with mild to moderate hair loss were randomized to either Ashwagandha (topical) or Placebo (topical) treatment. The participants were assessed at Day-1 and Day-75 for change in efficacy parameters, which included 60 Seconds Hair Comb, Trichoscan analysis, Hair Pull test, Investigator's Global Assessment (IGA) and QoL using Hair-specific Skindex-29. RESULTS In the per protocol analysis of 61 participants, Ashwagandha group demonstrated significant reduction in hair shedding in the 60 Seconds Hair Comb test compared to Placebo at day 75. Similarly, Ashwagandha substantially enhanced hair density, growth, and thickness compared to the Placebo group (density = 7.3 vs. 2.8, P < 0.001; growth = 21.7 vs. 4.2, P < 0.001; thickness = 1.8 vs. 0.9, P < 0.001). In addition, Ashwagandha significantly improved QOL compared to placebo (Score = -17.3 vs. -6.1, P = 0.011). CONCLUSION The study found that topical Ashwagandha (serum) improved hair growth and hair health indicators. Thus, it can be an effective and safer alternative for alopecia.

Abstract
Alopecia is a treatable benign disease, however, approximately 15-30% of women and 50% of men suffer from alopecia, which greatly affects patient's self-esteem and quality of life. Currently, commercial products for alopecia treatment include topical minoxidil solution, oral finasteride tablets and oral baricitinib tablets. However, the barrier of stratum corneum, systemic adverse effects and poor cure rate limit the application of commercial products. Therefore, researchers investigated the mechanism of alopecia, and developed new drugs that could target lactate dehydrogenase-related pathways, remove excessive reactive oxygen in hair follicles, and reduce the escape of hair follicle stem cells, thus injecting new strength into the treatment of alopecia. Moreover, starting from improving drug stratum corneum penetration and reducing side effects, researchers have developed hair loss treatment strategies based on dissolved microneedles (MNs), such as drug powders/microparticles, nanoparticles, biomimetic cell membranes, phototherapy and magnetically responsive soluble microneedles, which show exciting alopecia treatment effects. However, there are still some challenges in the practical application of the current alopecia treatment strategy with soluble microneedles, and further studies are needed to accelerate its clinical translation.

Abstract
The endocannabinoid system has been shown to be involved in various skin functions, such as melanogenesis and the maintenance of redox balance in skin cells exposed to UV radiation, as well as barrier functions, sebaceous gland activity, wound healing and the skin's immune response. In addition to the potential use of cannabinoids in the treatment and prevention of skin cancer, cannabinoid compounds and derivatives are of interest as potential systemic and topical applications for the treatment of various inflammatory, fibrotic and pruritic skin conditions. In this context, cannabinoid compounds have been successfully tested as a therapeutic option for the treatment of androgenetic alopecia, atopic and seborrhoeic dermatitis, dermatomyositis, asteatotic and atopic eczema, uraemic pruritis, scalp psoriasis, systemic sclerosis and venous leg ulcers. This review provides an insight into the current literature on cannabinoid compounds as potential medicines for the treatment of skin diseases.

Abstract
The development of painless hair loss therapy without side-effect is challenging. The dermal papilla is the signal center of hair follicles and plays a key role in the regulation of their cycling. Activation of dermal papilla cells (DPCs) would promote hair regeneration. In this study, a separable microneedle patch comprised of chitosan lactate (CL) and exosomes (EXO) from adipose-derived stem cells is fabricated. After insertion of the microneedle into the skin, the hyaluronic acid substrate dissolves fast and the swellable polyvinyl alcohol needles are retained. The EXO sustainedly released from needles can be endocytosed by DPCs and promote cell proliferation via the activation of the Wnt signaling pathway, while the L-lactate released by CL can promote cell growth by activating lactate dehydrogenase. CL and EXO synergetically facilitate hair regeneration through regulating hair follicle cycling. In animal tests, compared with topical administration of minoxidil, the drug-free microneedle patches can more significantly promote hair regeneration within 7 days with lower dosing frequency. Furthermore, the inherent antibacterial properties of CL make it possible to avoid potential infection. Such transdermally administrated drug-free microneedle patches provide a simple, safe, and efficient strategy for hair loss treatment and exhibit great potential in clinical application.

Effectiveness of Platelet-Rich Plasma Therapy in Androgenic Alopecia—A Meta-Analysis. J Pers Med 2022; 12:jpm12030342. [PMID: 35330343 PMCID: PMC8953144 DOI: 10.3390/jpm12030342] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 02/22/2022] [Accepted: 02/22/2022] [Indexed: 01/25/2023] Open
Abstract
Platelet-rich plasma (PRP) represents a novel therapy tested and is used more and more frequently in dermatology and cosmetic surgery for a variety of conditions, including androgenic alopecia (AGA), a common condition with a complex pathogenesis involving genetic factors, hormonal status and inflammation. We performed an extensive literature search which retrieved 15 clinical trials concerning the use in AGA of PRP therapy, alone or in combination, in male, female or mixed patient groups. A quantitative statistical meta-analysis of n = 17 trial groups proved significant increases in hair density from 141.9 ± 108.2 to 177.5 ± 129.7 hairs/cm2 (mean ± SD) following PRP (p = 0.0004). To the best of our knowledge, this is the first meta-analysis that proved a statistically significant correlation between the number of PRP treatments per month and the percentage change in hair density (r = 0.5, p = 0.03), as well as a negative correlation between the mean age of treatment group and the percentage change in hair density (r = −0.56, p = 0.016). Other factors considered for analysis were the PRP preparation method, amount used per treatment, hair diameter, terminal hairs and pull test. We conclude that PRP represents a valuable and effective therapy for AGA in both males and females if patients are rigorously selected.

Abstract
Androgenetic alopecia is a multifactorial condition characterized by noticeable hair loss, affecting both men and women and representing a debilitating and chronic disorder that considerably affects the quality of life. Available topical treatments based on minoxidil or finasteride require repeated applications and are associated with a certain number of adverse effects. The challenges associated with current treatments pave the way for the research of new therapeutic strategies, more precise and selective, and capable of providing long-term results. In this context, the present review examines the new proposed formulation strategies to deliver 5-α-reductase inhibitors in order to obtain a targeted drug delivery, for improving drug retention at the site of action in the hair follicle, contemporaneously reducing drug systemic absorption, which is the cause of important adverse effects. In particular, the research will be focused on the several aspects that influence the performance of nanostructured drug delivery systems in creating a depot in the hair follicles, such as particle size, surface charge, excipients, and combined application with external stimuli (infrared radiation, mechanical massage, ultrasounds application).

Abstract
Alopecia is a clinical condition related to hair loss that can significantly affect both male and female adults' quality of life. Despite the high market demand, only few drugs are currently approved for alopecia treatment. Topical formulations still bring drawbacks, such as scalp irritation with frequent use, and low drug absorption to the site of action, which limits the efficacy. The most recent research points out that different formulation technology could circumvent the aforementioned flaws. Such technology includes incorporation of drugs in rigid or deformable nanoparticles, strategies involving physical, energetical and mechanical techniques, such as iontophoresis, sonophoresis, microneedling, and the use of solid effervescent granules to be hydrated at the moment of application in the scalp. In this paper, the progress of current research on topical formulations dedicated to the treatment of alopecia is reviewed and discussed.

Abstract
Finasteride, a 5-alpha reductase (5α-R) inhibitor, is a widely used drug for treating androgen-dependent conditions. However, its use is associated with sexual, psychological, and physical complaints, suggesting that other mechanisms, in addition to 5α-R inhibition, may be involved. Here, a multidisciplinary approach has been used to identify potential finasteride off-target proteins. SPILLO-PBSS software suggests an additional inhibitory activity of finasteride on phenylethanolamine N-methyltransferase (PNMT), the limiting enzyme in formation of the stress hormone epinephrine. The interaction of finasteride with PNMT was supported by docking and molecular dynamics analysis and by in vitro assay, confirming the inhibitory nature of the binding. Finally, this inhibition was also confirmed in an in vivo rat model. Literature data indicate that PNMT activity perturbation may be correlated with sexual and psychological side effects. Therefore, results here obtained suggest that the binding of finasteride to PNMT might have a role in producing the side effects exerted by finasteride treatment.

Abstract
Androgenetic alopecia (AGA) is a dihydrotestosterone (DHT)-mediated hair loss disorder characterized by shortened anagen hair cycle. Oligosaccharides derived from seaweeds possess diverse biological functions. However, little is known about their effects on AGA. In this study, algal oligosaccharide (AOS) was characterized for its mitigation effects on key features involved in AGA pathogenesis, such as DHT- mediated cellular signaling and shortened anagen hair cycle. AOS with varying degrees of polymerization (DP), namely, AOS (DP2), AOS (DP4-6), and AOS (DP8-12), were prepared by agar biodegradation with Flammeovirga pacifica WPAGA1, an agarolytic bacterium isolated from deep-sea sediments. In vitro results showed that AOS with varying DPs significantly ameliorated the DHT-induced alterations of regulatory factors in human hair follicle dermal papilla cells in a dose- and DP-dependent manner, as revealed by the normalization of several hair-growth-stimulating or inhibitory factors. In vivo studies showed that AOS (DP2) extended the anagen phase and thereby delayed catagen progression in mice. Furthermore, AOS (DP2) stimulated dorsal hair growth in mice by increasing hair length, density, and thickness. Therefore, our findings indicated that AOS antagonized key factors involved in AGA pathogenesis, suggesting the potential application of AOS in the prevention and the treatment of AGA.

Abstract
Androgenic alopecia (AGA) is the most common alopecia that is heritable, androgen-dependent and occurs in both sexes with defined patterns such as Male pattern hair loss in men and Female pattern hair loss in women. AGA affects at least 50 % of men by the age of 50 years, and up to 70 % of all males in later life.
The aim.The research was aimed to substantiate the optimal concentration of excipients and active pharmaceutical ingredients (APIs) of the emulgel intended for the topical treatment of androgenic alopecia.
Materials and methods. In this study the samples of the emulgel bases containing different carbomer Ultrez10 concentrationsin the range of 0.3–0.6 % and its neutralizers (0.1 % of potassium sorbate and 0 % or 0.2 % of triethanolamine) were used. Colloidal and thermal stability, pH, rheological properties (structural viscosity, mechanical stability, degree of thixotropy) of these samples were determined. The emulgel samples with different percentages of the Serenoa repens dry extract and the Sophora japonica tincture were used in the biopharmaceutical studies. The samples of the emulgel with the antioxidant butylhydroxytoluene different concentrations (0 %, 0.01 %, 0.02 %, 0.03 %) were used to determine acid value during 1 year of the emulgel storage.
Results and discussion. It was experimentally substantiated the optimal ratio of the emulgel ingredients that provide good APIs release and necessary consumer properties of the semi-solid remedy like application compliance, safety and storage stability.
Conclusions. Physicochemical, rheological and biopharmaceutical properties of emulgel bases have been studied. It was found that the base №2 (in which the concentrations of Carbomer Ultraz 10, potassium sorbate and triethanolamine are 0.3 %, 0.1 %, 0.2 % respectively) possessed the optimal properties. Considering the results of the complete range of experimental research it was developed the final formulation of the emulgel intended for AGA treatment which included the concentration of the APIs, neutralizers, preservatives, antioxidant and fragrance.

Abstract
Background Androgenetic alopecia (AGA) represents the most frequent clinical complaint encountered by dermatologists and is characterized by a progressive miniaturization of the hair follicle. However, the efficacy and safety of current medical treatment remain limited, and more personalized therapeutic approaches for AGA are needed. Therefore, the present study is aimed at investigating the efficacy and safety of botulinum toxin type A (BTA) in patients with AGA. Methods 63 patients with AGA meeting the inclusion criteria were included in this study and treated with BTA injection or BTA injection combined with oral finasteride (FNS). In the scalp, 30 sites were injected with 100 U of BTA in each site and patients received BTA after every 3 months for a total of 4 times. Hair counts, head photographs, evaluation scores, and self-assessment were assessed in patients with AGA. Results Hair counts in both groups at all time points were significantly higher as compared with those before treatment. After 4 times of treatment, hair counts in the BTA+FNS group were higher than those in the BTA group. Hair growth and density were significantly augmented, and the area of hair loss was attenuated after each treatment as revealed by head photographs. The effective rates of BTA and BTA+FNS groups were 73.3% and 84.8%, respectively, following 4 times treatment. Conclusion BTA is a safe and effective therapeutic strategy for the treatment of AGA without adverse effects, and BTA combined with FNS exhibited a superior therapeutic effect than BTA alone.
