Patient-reported outcomes of topical finasteride/minoxidil treatment for male androgenetic alopecia: A retrospective study using telemedical data. J Cosmet Dermatol 2024; 23:2956-2963. [PMID: 38713003 DOI: 10.1111/jocd.16360] [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: 09/06/2023] [Revised: 03/14/2024] [Accepted: 04/24/2024] [Indexed: 05/08/2024]
Abstract
BACKGROUND Oral finasteride and topical minoxidil are the current standard of care for male androgenetic alopecia and a combination of the two treatments can be considered for greater efficacy. Clinical trials of topical finasteride have also yielded promising results, but routine care data are lacking. AIMS To examine patient-reported outcomes of men with androgenetic alopecia who received topical finasteride admixed with minoxidil compared to the current standard of care (oral finasteride). METHODS Retrospective, cross-sectional study with data from a German direct-to-consumer teledermatology platform between December 2021 and January 2023. Patient-reported outcomes were collected through voluntary follow-up questionnaires provided after 6 weeks on topical finasteride/minoxidil or oral finasteride treatment. RESULTS A total of 1545 patients who received topical finasteride/minoxidil treatment were included; 238 (15.4%) participated in the follow-up questionnaire. At week six, 62.2% (148/238) reported positive changes in their hair appearance, and 44.1% (105/238) reported an improvement of self-esteem. Treatment-related adverse events were reported in 11.8% (28/238). Full treatment adherence was observed in 74.4% (177/238). Comparing the topical treatment group to those receiving oral finasteride, lower treatment adherence was reported, along with higher rates of local adverse events; no difference was found in the incidence of sexual adverse events. CONCLUSION Based on patient-reported outcomes, topical finasteride/minoxidil seems to be effective and well tolerated, but not superior to oral finasteride. Lower treatment adherence for topical usage must be considered when considering treatment options. Additional real-world data are needed to further evaluate the efficacy and safety of topical finasteride/minoxidil.

Abstract
Androgenetic alopecia (AGA) is the most prevalent type of hair loss. Its morbility is mainly psychological although an increased incidence in melanoma has also been observed in affected subjects. Current drug based therapies and physical treatments are either unsuccessful in the long term or have relevant side effects that limit their application. Therefore, a new therapeutic approach is needed to promote regenerative enhancement alternatives. These treatment options, focused on the cellular niche restoration, could be the solution to the impact of dihydrotestosterone in the hair follicle microenvironment. In this context emerging regenerative therapies such as Platelet-rich plasma or Platelet-rich fibrine as well as hair follicle stem cells and mesenchymal stem cell based therapies and their derivatives (conditioned medium CM or exoxomes) are highlighting in the evolving landscape of hair restoration. Nanotechnology is also leading the way in AGA treatment through the design of bioinks and nanobiomaterials whose structures are being configuring in a huge range of cases by means of 3D bioprinting. Due to the increasing number and the rapid creation of new advanced therapies alternatives in the AGA field, an extended review of the current state of art is needed. In addition this review provides a general insight in current and emerging AGA therapies which is intented to be a guidance for researchers highlighting the cutting edge treatments which are recently gaining ground.

Abstract
BACKGROUND Oral finasteride and topical minoxidil formulations are the only FDA-approved drug therapies for androgenetic alopecia (AGA). Research into dutasteride, topical finasteride, and nontopical minoxidil (low-dose oral and sublingual) formulations in the treatment of AGA has spiked within recent years. Early findings show that these alternative drug therapies may have similar to improved efficacy and safety profiles relative to the conventional treatment options. AIMS Conducting a bibliometric analysis, compare trends in publications on these alternative drug therapies, identify key contributors, evaluate major findings from top-cited articles, and elucidate gaps in evidence. METHODS A search was conducted on the Web of Science database for publications on the use of alternative drug therapies in the treatment of AGA. A total of 95 publications, published between January 2003-March 2024, and their citation metadata were included in the analysis. RESULTS Dutasteride showed the greatest (n = 37) and longest (20+ years) history of publications, as well as the highest cumulative citations (n = 914); however, nontopical minoxidil showed a burst in research activity within the last 5 years (n = 33 publications since 2019). A relatively low number of randomized control trials (n = 3) for nontopical minoxidil suggests a need for higher-quality evidence. CONCLUSIONS Our analysis reveals major trends, contributors, and gaps in evidence for alternative drug therapies for AGA, which can help inform researchers on their future projects in this growing field of study. There is enthusiasm for exploring off-label formulations: nontopical forms of minoxidil (oral and sublingual), topical finasteride, and mesotherapy.

Abstract
Although finasteride (FNS) tablets are considered the most effective drug for the treatment of androgenetic alopecia (AGA), their clinical applications are limited due to the associated side effects including decreased libido, breast enlargement, and liver dysfunction. In this study, we have developed a personalized microneedle (PMN) with a double-layer structure that incorporates FNS-loaded microspheres (MPs) to accommodate irregular skin surfaces. This design enables the sustained release of FNS, thereby reducing potential side effects. The needle body was synthesized with high-strength hyaluronic acid (HA) as the base material substrate. The backing layer utilized methacrylate gelatin (GelMA) with specific toughness, enabling PMN to penetrate the skin while adapting to various skin environments. The length of PMN needles (10 × 10) was approximately 600 μm, with the bottom of the needles measuring about 330 μm × 330 μm. The distance between adjacent tips was around 600 μm, allowing the drug to penetrate the stratum corneum of the skin. The results of the drug release investigation indicated the sustained and regulated release of FNS from PMN, as compared to that of pure FNS and FNS-MPs. Further, the cytotoxicity assay demonstrates that PMS displays good cytocompatibility. Altogether, this mode of administration has immense potential for the development of delivery of other drugs, as well as in the medical field.

Abstract
Androgenetic alopecia is a common type of hair loss, which is generally influenced by genetic factors and systemic androgens resulting in follicular miniaturization.1 It can cause cosmetic problems leading to psychological distress among affected men and women. Effective standard medical treatments available are topical minoxidil 2 to 5%, oral finasteride, oral dutasteride, and hair transplantation.1 However, some patients do not achieve favorable results with standard treatments. For these reasons, other novel treatments have been developed, including new medications, regenerative medicines (autologous platelet-rich plasma, adipose-derived stem cells, micrograft generation, and exosome), and low-level laser therapy.

Abstract
Skin-mediated drug delivery methods currently are receiving significant attention as a promising approach for the enhanced delivery of drugs through the skin. Skin-mediated drug delivery offers the potential to overcome the limitations of traditional drug delivery methods, including oral administration and intravenous injection. The challenges associated with drug permeation through layers of skin, which act as a major barrier, are explored, and strategies to overcome these limitations are discussed in detail. This review categorizes skin-mediated drug delivery methods based on the means of increasing drug permeation, and it provides a comprehensive overview of the mechanisms and techniques associated with these methods. In addition, recent advancements in the application of skin-mediated drug delivery are presented. The review also outlines the limitations of ongoing research and suggests future perspectives of studies regarding the skin-mediated delivery of drugs.

Efficacy of the association of topical minoxidil and topical finasteride compared to their use in monotherapy in men with androgenetic alopecia: A prospective, randomized, controlled, assessor blinded, 3-arm, pilot trial. J Cosmet Dermatol 2024; 23:502-509. [PMID: 37798906 DOI: 10.1111/jocd.15953] [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: 03/29/2023] [Revised: 06/29/2023] [Accepted: 07/29/2023] [Indexed: 10/07/2023]
Abstract
PURPOSE Topical minoxidil (MNX) 2%-5% and oral finasteride (F) 1 mg/day are the only two pharmacological treatments authorized for androgenetic alopecia (AGA). Recently, a 2.2 mg/mL topical formulation of F was developed to minimize the systemic adverse effects associated with the oral formula. MNX and F act through different mechanisms; therefore, their association could improve clinical efficacy. To evaluate the efficacy of the association of 5% MNX and 0.25% topical F compared to their use in monotherapy, a 6-month, prospective, randomized, assessor-blinded trial was conducted. PATIENTS AND METHODS Forty-two males, mean age 24 ± 3 years, with AGA (I-VII of Norwood-Hamilton Grading Scale), treatment naive or free from any therapy for at least 6 months, were enrolled and randomly assigned to three arm treatment groups (2:1:1): group A (n = 19, the subjects applied 5% MNX in the morning and F spray in the evening), group B (n = 12, the subjects applied F spray in the evening), and group C (n = 11, the subjects applied 5% MNX twice daily). The efficacy of treatments was evaluated at baseline and after 3 and 6 months using a global photography score (GPAS; from -3 to +3) and trichoscopy evaluation and assessed by an investigator unaware of treatment allocation. At baseline and after treatments, the serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), dehydroepiandrosterone sulfate (DHEA-S), and testosterone were also evaluated. RESULTS All treatments resulted in an increase in hair density compared to baseline. However, this improvement was significant only for group A (MNX + F), both at three (+56 density/cm2 , p < 0.05) and six (+81 density/cm2 , p < 0.001) months. The mean change from baseline in hair density was higher for group A compared to other groups and statistically different compared to group B (F) (p < 0.01), both after 3 and 6 months. Group A showed a global photographic assessment score (GPAS) significantly higher compared to group B (p < 0.001) and group C (p < 0.05) both at 3 and 6 months (2.0 ± 0.7 vs. 0.6 ± 0.8 and 1.3 ± 0.6; respectively). A significantly greater percentage of subjects in Group A achieved a GPAS score of ≥2 in comparison with Groups B and C both after 3 and 6 months (79% vs. 8% and 41%, respectively). No significant differences were observed in mean hair diameter and hormonal levels between the three groups. Good tolerability was observed in all treated groups. CONCLUSION The association of 5% MNX lotion and 0.25% F in spray formulation in patients with AGA showed a significantly higher clinical and instrumental efficacy compared to the monotherapies, with comparable tolerability and safety profile.

Abstract
Topical and transdermal drug delivery are advantageous administration routes, especially when treating diseases and conditions with a skin etiology. Nevertheless, conventional dosage forms often lead to low therapeutic efficacy, safety issues, and patient noncompliance. To tackle these issues, novel topical and transdermal platforms involving nanotechnology have been developed. This review focuses on the latest advances regarding the development of nanoemulgels for skin application, encapsulating a wide variety of molecules, including already marketed drugs (miconazole, ketoconazole, fusidic acid, imiquimod, meloxicam), repurposed marketed drugs (atorvastatin, omeprazole, leflunomide), natural-derived compounds (eucalyptol, naringenin, thymoquinone, curcumin, chrysin, brucine, capsaicin), and other synthetic molecules (ebselen, tocotrienols, retinyl palmitate), for wound healing, skin and skin appendage infections, skin inflammatory diseases, skin cancer, neuropathy, or anti-aging purposes. Developed formulations revealed adequate droplet size, PDI, viscosity, spreadability, pH, stability, drug release, and drug permeation and/or retention capacity, having more advantageous characteristics than current marketed formulations. In vitro and/or in vivo studies established the safety and efficacy of the developed formulations, confirming their therapeutic potential, and making them promising platforms for the replacement of current therapies, or as possible adjuvant treatments, which might someday effectively reach the market to help fight highly incident skin or systemic diseases and conditions.

Abstract
We aimed to determine the efficacy of the various available oral, topical, and procedural treatment options for hair loss in individuals with androgenic alopecia. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic review of the National Library of Medicine was performed. Overall, 141 unique studies met our inclusion criteria. We demonstrate that many over the counter (e.g. topical minoxidil, supplements, low-level light treatment), prescription (e.g. oral minoxidil, finasteride, dutasteride), and procedural (e.g. platelet-rich plasma, fractionated lasers, hair transplantation) treatments successfully promote hair growth, highlighting the superiority of a multifaceted and individualized approach to management.

Abstract
Hair loss, or alopecia, is a prevalent condition in modern society that imposes substantial mental and psychological burden on individuals. The types of hair loss, include androgenetic alopecia, alopecia areata, and telogen effluvium; of them, androgenetic alopecia is the most common condition. Traditional treatment modalities mainly involve medical options, such as minoxidil, finasteride and surgical interventions, such as hair transplantation. However, these treatments still have many limitations. Therefore, exploring the pathogenesis of hair loss, specifically focusing on the development and regeneration of hair follicles (HFs), and developing new strategies for promoting hair regrowth are essential. Some emerging therapies for hair loss have gained prominence; these therapies include low-level laser therapy, micro needling, fractional radio frequency, platelet-rich plasma, and stem cell therapy. The aforementioned therapeutic strategies appear promising for hair loss management. In this review, we investigated the mechanisms underlying HF development and regeneration. For this, we studied the structure, development, cycle, and cellular function of HFs. In addition, we analyzed the symptoms, types, and causes of hair loss as well as its current conventional treatments. Our study provides an overview of the most effective regenerative medicine-based therapies for hair loss.

Abstract
Androgenetic alopecia (AGA) is the primary hair loss with impairing patients' quality of life. Finasteride (FIN) is an SRD5A2 inhibitor for AGA treatment, but oral FIN causes systemic adverse effects. Topical FIN delivery is anticipated to overcome this problem. Ferulic acid (FA) is a natural phenolic acid with vascular remodeling and anti-inflammatory effects. Herein, an active pharmaceutical ingredient ionic liquid (API IL) based on choline and FA (CF-IL) is for the first time constructed to load FIN for fabricating FIN CF-IL. CF-IL aims to act as carriers and cargos and enhance hair follicle (HF) co-delivery of FA and FIN for synergistic anti-alopecia. Thermal and spectroscopic analysis combined with quantum chemistry calculations and molecular dynamics confirm the formation of CF-IL. The CF-IL simultaneously increases the solubility of FA (∼648-fold) and FIN (∼686-fold), enhances the permeation and retention of FIN and FA through the follicular pathway, and promotes cellular uptake. FIN CFIL regulates the abnormal mRNA expressions in dihydrotestosterone-irritated hDPCs, and promotes hair regrowth in AGA mice in a combined manner with FIN and FA. These findings suggest that FA-based API IL is a promising approach for percutaneously co-delivering FA and FIN to HF, providing an enhanced targeting treatment for AGA.

Int J Mol Sci 2023; 24:17461. [PMID: 38139289 PMCID: PMC10744313 DOI: 10.3390/ijms242417461] [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: 11/10/2023] [Revised: 12/05/2023] [Accepted: 12/08/2023] [Indexed: 12/24/2023] Open
Abstract
Androgenic alopecia (AGA) is the most prevalent type of progressive hair loss and has psychological repercussions. Nevertheless, the effectiveness of current pharmacological treatments remains limited, in part because the molecular basis of the disease has not been fully elucidated. Our group previously highlighted the important roles of aromatase and 5α-reductase (5α-R) in alopecia in young women with female pattern hair loss. Additionally, an association has been proposed between AGA and prostate cancer (PCa), suggesting that genes implicated in PCa would also be involved in AGA. A low-invasive, sensitive, and precise method was used to determine mRNA levels of aromatase, 5α-R isozymes, and 84 PCa-related genes in samples of plucked hair from young men with AGA and controls. Samples were obtained with a trichogram from the vertex scalp, and mRNA levels were quantified using real-time RT-PCR. The men with AGA had significantly higher 5α-R2 mRNA levels in comparison to controls; interestingly, some of them also showed markedly elevated mRNA levels of 5α-R1 or 5α-R3 or of both, which may explain the varied response to 5α-R inhibitor treatments. The men with AGA also showed significant changes versus controls in 6 out of the 84 genes implicated in PCa. This study contributes greater knowledge of the molecular bases of AGA, facilitating early selection of the most appropriate pharmacological therapy and opening the way to novel treatments.

Oral and Topical Administration of a Standardized Saw Palmetto Oil Reduces Hair Fall and Improves the Hair Growth in Androgenetic Alopecia Subjects - A 16-Week Randomized, Placebo-Controlled Study. Clin Cosmet Investig Dermatol 2023; 16:3251-3266. [PMID: 38021422 PMCID: PMC10648974 DOI: 10.2147/ccid.s435795] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 10/24/2023] [Indexed: 12/01/2023]
Abstract
Purpose Androgenetic alopecia (AGA) is the most common type of hair loss in humans, affecting self-esteem and emotional well-being. This study aimed to assess the safety and efficacy of VISPOTM, a standardized saw palmetto oil (2-3% β-sitosterol), in subjects with mild-to-moderate AGA. Methods In a double-blind, placebo-controlled, four-arm clinical study, 80 healthy male and female subjects aged 18-50 years were randomly allocated (1:1:1:1) to receive either 400 mg capsules of VISPO or 5 mL of a topical formulation containing 20% VISPO or the respective placebo once daily for 16 weeks. The primary endpoints included hair count (hair comb and hair pull tests) and the self-assessment of perceived efficacy. Objective evaluation was performed using the global photographic assessment score. Hair density, thickness, and anagen/telogen ratio were evaluated using phototrichogram analysis. Results At the end of the study, oral and topical formulations of VISPO reduced hair fall by up to 29% (p<0.001) and 22.19% (p<0.01) from the baseline, respectively. Hair density increased by 5.17% and 7.61% in the oral and topical VISPO groups, respectively (p<0.001). In addition, oral ingestion of VISPO resulted in a marked reduction in serum dihydrotestosterone (DHT) levels in the subjects compared to placebo (p<0.001). However, the effect of the VISPO formulations on the anagen/telogen ratio was insignificant. No serious adverse effects were observed during the study. Conclusion VISPO formulations reduced hair fall and promoted hair regrowth and scalp appearance in AGA patients.

Abstract
The hair follicle (HF) is a multicellular complex structure of the skin that contains a reservoir of multipotent stem cells. Traditional hair repair methods such as drug therapies, hair transplantation, and stem cell therapy have limitations. Advances in nanotechnology offer new approaches for HF regeneration, including controlled drug release and HF-specific targeting. Until recently, embryogenesis was thought to be the only mechanism for forming hair follicles. However, in recent years, the phenomenon of wound-induced hair neogenesis (WIHN) or de novo HF regeneration has gained attention as it can occur under certain conditions in wound beds. This review covers HF-specific targeting strategies, with particular emphasis on currently used nanotechnology-based strategies for both hair loss-related diseases and HF regeneration. HF regeneration is discussed in several modalities: modulation of the hair cycle, stimulation of progenitor cells and signaling pathways, tissue engineering, WIHN, and gene therapy. The HF has been identified as an ideal target for nanotechnology-based strategies for hair regeneration. However, some regulatory challenges may delay the development of HF regeneration nanotechnology based-strategies, which will be lastly discussed.

Abstract
BACKGROUND Androgenetic alopecia (AGA) is the most common cause of chronic progressive hair loss in men, and AGA has a severe negative impact on the quality of life and physical and mental health of patients. METHODS Four female C57BL/6 mice were isolated from DP cells in culture (≤4 generations) after stimulation of DPC proliferation by herbal concentrations obtained by the CCK-8 method, and exosomes were isolated by differential centrifugation at low temperature. Testosterone propionate and topical hair removal treatments were used together to establish the C57BL/6 mouse AGA model, which was treated with LTF, 5% minoxidil, and LTF-DPC-EXO, respectively. ELISA was used to detect serum hormone levels, in vivo tracing was used to observe dynamic changes in exosomes, H&E staining showed changes in mouse hair follicle tissue, and (q) RT-PCR and WB were used to detect dorsal skin VEGF, AKT1, and CASP3 expression in dorsal skin tissues. RESULTS Hair regeneration was significant in the LTF group, minoxidil group, and LTF-DPC-EXO group mice, and the hair growth was only seen in the local skin in the model group. The hormone T in all treatment groups was lower than that in the model group, and e2 was higher than that in the model group. (q) RT-PCR and western blot showed that VEGF and AKT1 expressions were upregulated and Caspase3 expression was downregulated in the skin sections of mice in the treatment groups. CONCLUSION DPC-EXO obtained through LTF may activate AKT1 and VEGF in the PI3K/AKT signaling pathway to inhibit CASP3, thereby protecting DPC to restore the hair growth.

Abstract
Macromolecules are large, complex molecules composed of smaller subunits known as monomers. The four primary categories of macromolecules found in living organisms are carbohydrates, lipids, proteins, and nucleic acids; they also encompass a broad range of natural and synthetic polymers. Recent studies have shown that biologically active macromolecules can help regenerate hair, providing a potential solution for current hair regeneration therapies. This review examines the latest developments in the use of macromolecules for the treatment of hair loss. The fundamental principles of hair follicle (HF) morphogenesis, hair shaft (HS) development, hair cycle regulation, and alopecia have been introduced. Microneedle (MN) and nanoparticle (NP) delivery systems are innovative treatments for hair loss. Additionally, the application of macromolecule-based tissue-engineered scaffolds for the in vitro and in vivo neogenesis of HFs is discussed. Furthermore, a new research direction is explored wherein artificial skin platforms are adopted as a promising screening method for hair loss treatment drugs. Through these multifaceted approaches, promising aspects of macromolecules for future hair loss treatments are identified.

Abstract
Finasteride and dutasteride are 5-alpha reductase selective inhibitors (5ARIs). They were introduced as therapeutic agents for the treatment of benign prostatic hyperplasia in 1992 and 2002, respectively; finasteride has also been approved for the treatment of androgenetic alopecia since early 2000. These agents inhibit the conversion of testosterone (T) to 5α-dihydrotestosterone (5α-DHT), limiting steroidogenesis and playing a crucial role in the physiological function of the neuroendocrine system. Therefore, it has been proposed that blocking androgen synthesis with the use of 5ARIs would be beneficial in the treatment of various diseases related to states of hyperandrogenism. This review describes the dermatological pathologies in which 5ARIs have been used as part of the treatment, evaluation of the efficacy, and knowledge of the safety profile. Specifically, we discuss the application of 5ARIs in androgenetic alopecia, acne, frontal fibrosing alopecia, hirsutism, and the implications of adverse events associated with its use to inform about the applications of 5ARIs in general dermatology practice.

Abstract
Androgenic alopecia (AGA), commonly known as male pattern baldness (MPB), is a hereditary condition characterized by hair follicles that are sensitive to androgens. This article focuses on examining the recent advancements in the comprehension and management of AGA. The genetic factors and pathophysiology of AGA, including the role of dihydrotestosterone (DHT) and the androgen receptor gene, are discussed. The consequences of hair loss on self-esteem and identity, as well as on mental health, are examined. Diagnostic methods, such as the hair-pull test and trichoscopy, are discussed. The article also presents the Hamilton-Norwood classification, which is the most commonly employed system for classifying MPB. The article then delves into the various treatment options available, including topical minoxidil, oral finasteride, platelet-rich plasma therapy, low-level light therapy, hair transplant, and other alternative treatments. The efficacy and combination therapies for these treatments are examined. Additionally, emerging treatments such as caffeine-based solutions and prostaglandin inhibitors are discussed. By examining the recent advancements in AGA treatment, this article provides a comprehensive overview for healthcare professionals to make informed decisions when selecting the best treatment options for their patients.

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
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
OBJECTIVE To evaluate the efficacy of platelet-rich plasma (PRP) in the treatment of androgenetic alopecia, as well as establish an effective treatment protocol and optimal PRP preparation procedure. METHODS We searched the PubMed, Scopus, Embase, Cochrane, CNKI, and Wanfang databases from inception to October 29, 2021, using PROSPERO's International Prospective Register of Systematic Reviews (registration ID: CRD42022295921). RESULTS The original literature search revealed 215 reviews; after duplication removal, 89 papers were eliminated, 95 were eliminated after reading the titles and abstracts, and eventually, 28 articles were included after reading the complete text. CONCLUSIONS PRP treatment for androgenetic alopecia is effective, and we recommend the following: (1) a PRP volume of at least 0.05 ml/cm2 , preferably 0.1 ml/cm2 ; (2) at least three consecutive treatments at an interval of 1 month; (3) intensive therapy is beneficial and can be provided from 3 to 6 months after continuous treatment; (4) objective indicators such as hair diameter, hair count; (5) long-term follow-up.

Abstract
Pediatric androgenetic alopecia is an underrecognized disorder. A clinical evaluation with trichoscopy should be made in children and adolescents with hair loss and/or reduced hair density. Diagnosis is usually clinical, by observation of the hair loss pattern and performance of trichoscopy. In some cases, hyperandrogenism should be excluded. Although there is no approved therapy for androgenetic alopecia in pediatric age, topical minoxidil, oral minoxidil and topical finasteride may be very useful. Hair transplant may be an option for girls in selected cases. This article is a review of the current state of evidence concerning pediatric androgenetic alopecia.

Abstract
BACKGROUND Long noncoding RNAs (lncRNAs) can be used as competitive endogenous RNAs (ceRNAs) to bind to microRNAs (miRNAs) to regulate gene expression. Previous studies have demonstrated that ceRNAs play an important role in the development of tumors. However, it is not clear whether the lncRNA-miRNA-mRNA ceRNA network plays a role in androgenic alopecia (AGA). METHODS The hair follicles of three AGA patients and three healthy individuals were collected for high-throughput whole transcriptome sequencing to screen for differentially expressed lncRNAs. Differentially expressed lncRNA target genes were subjected to databases to predict miRNA-mRNA and lncRNA-miRNA relationship pairs, and a ceRNA network was constructed using Cytoscape software. Relative expression was verified by real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR). RESULTS 84 lncRNAs were significantly differentially expressed between the hair follicles of AGA patients and those of healthy individuals; 30 were upregulated, and 54 were downregulated. The top 10 upregulated lncRNAs were ENST00000501520, ENST00000448179, ENST00000318291, ENST00000568280, ENST00000561121, ENST00000376609, ENST00000602414, ENST00000573866, ENST00000513358, and ENST00000564194. The top 10 downregulated lncRNAs were ENST00000566804, ENST00000561973, ENST00000587680, ENST00000569927, ENST00000340444, ENST00000424345, ENST00000589787, NR_024344, NR_073026, and NR_110001. The qRT-PCR validation results and receiver-operating characteristic curve analysis indicated that one upregulated lncRNA, LOXL1-AS1 (ENST00000564194), had the most significant clinical diagnostic potential. After further analysis, it was concluded that LOXL1-AS1 could be used as a sponge to target hsa-miR-5193, thereby regulating TP53 expression. CONCLUSION The ceRNA network-regulating AGA was constructed through high-throughput sequencing. Our study also identified a key lncRNA that is possibly related to the AGA pathological process.

Gupta AK, Talukder M. Topical finasteride for male and female pattern hair loss: Is it a safe and effective alternative? J Cosmet Dermatol 2022; 21:1841-1848. [PMID: 35238144 DOI: 10.1111/jocd.14895] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 02/15/2022] [Accepted: 02/28/2022] [Indexed: 11/28/2022]
Abstract
Oral finasteride is an FDA-approved treatment for androgenetic alopecia (AGA). Topical finasteride, while not FDA approved, lacks the systemic adverse effects associated with oral finasteride. The efficacy of topical finasteride has been evaluated. A structured search in PubMed and Google Scholar identified 864 records, with 32 articles meeting the inclusion criteria for review. In a phase III, randomized, controlled trial, the efficacies of topical 0.25% w/w finasteride spray (1-4 sprays; 50-200 μL/day) and once-daily finasteride 1 mg oral tablet were similar when administered for 24 weeks (mean change from baseline, 20.2 vs. 21.1 hairs/cm2 ). Additionally, a double-blind, randomized trial compared the efficacies of twice-daily finasteride 1% topical gel and once-daily finasteride 1 mg oral tablet for six months, and found similar results in both groups. Also, a combination of topical minoxidil and topical finasteride may enhance efficacy. Topical finasteride reduces both scalp and plasma DHT levels. In an open-label pharmacodynamic study, a seven-day treatment of twice-daily finasteride 0.25% topical solution and once-daily finasteride 1 mg oral tablet provided similar inhibition of plasma DHT. Topical finasteride reduces the potential for systemic side effects, including the risk of sexual dysfunction. The side effects are localized to the application site, for example, scalp pruritus, burning sensation, irritation, contact dermatitis, and erythema. Topical finasteride may be an alternative for those concerned about the oral formulation's systemic side effects.

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).

Alleviation of Androgenetic Alopecia with Aqueous Paeonia lactiflora and Poria cocos Extract Intake through Suppressing the Steroid Hormone and Inflammatory Pathway. Pharmaceuticals (Basel) 2021; 14:ph14111128. [PMID: 34832910 PMCID: PMC8621879 DOI: 10.3390/ph14111128] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Revised: 10/30/2021] [Accepted: 11/04/2021] [Indexed: 01/28/2023] Open
Abstract
Paeonia lactiflora Pallas (PL) and Poria cocos Wolf (PC) have been traditionally used to treat inflammatory diseases reported in Dongui Bogam and Shen Nong Ben Cao Jing, traditional medical books in Korean and China, respectively. We determined the efficacies and the molecular mechanisms of PL, PC, and PL + PC aqueous extracts on androgenetic alopecia (AGA) induced by testosterone propionate in C57BL/6 mice. The molecular mechanisms of PL and PC in AGA treatment were examined using experimental assays and network pharmacology. The AGA model was generated by topically applying 0.5% testosterone propionate in 70% ethanol solution to the backs of mice daily for 28 days while the normal-control (Normal-Con; no AGA induction) mice applied 70% ethanol. The 0.1% PL (AGA-PL), 0.1% PC (AGA-PC), 0.05% PL + 0.05% PC (AGA-MIX), and 0.1% cellulose (AGA-Con; control) were supplemented in a high-fat diet for 28 days in AGA-induced mice. Positive-control (AGA-Positive) were administered 2% finasteride daily on the backs of the AGA mice. Hair growth rates decreased in the order of AGA-PL, AGA-MIX, AGA-PC, AGA-Positive, and AGA-Con after 21 days of treatment (ED21). On ED28, skins were completely covered with hair in the AGA-PL and AGA-MIX groups. Serum testosterone concentrations were lower in the AGA-PL group than in the AGA-Con group and similar to concentrations in the Normal-Con group, whereas serum 17β-estradiol concentrations showed the opposite pattern with increasing aromatase mRNA expression (p < 0.05). In the dorsal skin, DKK1 and NR3C2 mRNA expressions were significantly lower, but TGF-β2, β-Catenin, and PPARG expressions were higher in the AGA-PL and AGA-PC groups than in the AGA-Con group (p < 0.05), whereas TNF-α and IL-6 mRNA expressions were lower in the AGA-PL, AGA-MIX, and Normal-Con groups than in the AGA-Con group (p < 0.05). The phosphorylation of Akt and GSK-3β in the dorsal skin was lower in AGA-Con than normal-Con, and PL and MIX ingestion suppressed their decrease similar to the Normal-Con. In conclusion, PL or PL + PC intake had beneficial effects on hair growth similar to Normal-Con. The promotion was related to lower serum testosterone concentrations and pro-inflammatory cytokine levels, and inhibition of the steroid hormone pathway, consistent with network pharmacology analysis findings.
