Abstract
Vitamin D is a crucial vitamin that participates in various biological processes through the Vitamin D Receptor (VDR). While there are studies suggesting that VDR might regulate hair growth through ligand-independent mechanisms, the efficacy of Vitamin D in treating hair loss disorders has also been reported. Here, through in vivo experiments in mice, in vitro organ culture of hair follicles, and cellular-level investigations, we demonstrate that 1,25-(OH)2D3 promotes mouse hair regeneration, prolongs the hair follicle anagen, and enhances the proliferation and migration capabilities of dermal papilla cells and outer root sheath keratinocytes in a VDR-dependent manner. Transcriptome analysis of VDR-knockout mouse skin reveals the involvement of HIF-1α, NLRP3, and IL-1β in these processes. Finally, we confirm that 1,25-(OH)2D3 can counteract the inhibitory effects of DHT on hair growth. These findings suggest that 1,25-(OH)2D3 has a positive impact on hair growth and may serve as a potential therapeutic agent for androgenetic alopecia (AGA).

Abstract
Keratins, the most abundant proteins in human hair, are excellent hair nutrients for growth. However, the complex components of keratin extract hinder their mechanism investigation, and the pure recombinant keratin with poor solubility limited its hair growth promotion efficiency. Here, the water-soluble recombinant keratins (RKs) of K31 and K81 are rationally designed through QTY Code methodology, which are then used to fabricate the microneedles to study the effect of keratin on hair growth. Interestingly, it is discovered that more than 40% of the hair follicles (HFs) in the RK81QTY group entered the anagen on day 12 and the diameter of new hair is 15.10 ± 2.45 µm, which significantly promoted growth and development of HFs and improved new hair quality compared to RK31QTY. Water-soluble RKs significantly enhanced HFs activity and de novo regeneration of robust hairs compared to extract and minoxidil by upregulating the PI3K/AKT/Nf-κB signaling axis. These findings highlight the potential of designing solubilized recombinant keratins with distinct properties to improve therapeutical effects and open new avenues to designing keratin-based proteins.

Abstract
The collection of big data on skin and appendage phenotypes has revolutionized the field of personalized diagnosis and treatment by enabling the evaluation of individual characteristics and early detection of abnormalities. To establish a standardized system for collecting and measuring big data on phenotypes, a systematic categorization of measurement entries has been undertaken, accompanied by recommendations on measurement entries, environmental equipment requirements, and collection processes, tailored to the needs of different usage scenarios. Specific collection sites have also been recommended based on different index characteristics. A multi-center, multi-regional collaboration has been initiated to collect big date on phenotypes of healthy and diseased skin in the Chinese population. This data will be correlated with patient disease information, exploring the factors influencing skin phenotype, analyzing the phenotypic data features that can predict prognosis, and ultimately promoting the exploration of the pathophysiology and pathogenesis of skin diseases and therapeutic approaches. Non-invasive skin measurement robots are also in development. This consensus aims to provide a reference for the study of phenomics and the standardization of phenotypic measurements of skin and appendages in China.

Chang B, Bae J, Lee DS, Kim S. Hair growth-promoting effects of Enz_MoriL on human dermal papilla cells through modulation of the Wnt/β-Catenin and JAK-STAT signaling pathways. Arch Dermatol Res 2024; 316:290. [PMID: 38809465 DOI: 10.1007/s00403-024-02977-3] [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: 01/09/2024] [Revised: 04/22/2024] [Accepted: 04/26/2024] [Indexed: 05/30/2024]
Abstract
Enz_MoriL is a naturally occurring substance extracted from the leaves of Morus alba L. through enzymatic conversion. Historically, M. alba L. has been recognized for its potential to promote hair regrowth. However, the precise mechanism by which Enz_MoriL affects human hair follicle dermal papilla cells (hDPCs) remains unclear. The aim of this study was to investigate the molecular basis of Enz_MoriL's effect on hair growth in hDPCs. Interferon-gamma (IFN-γ) was used to examine the effects of Enz_MoriL on hDPCs during the anagen and catagen phases, as well as under conditions mimicking alopecia areata (AA). Enz_MoriL demonstrated the ability to promote cell proliferation in both anagen and catagen stages. It increased the levels of active β-catenin in the catagen stage induced by IFN-γ, leading to its nuclear translocation. This effect was achieved by increasing the phosphorylation of GSK3β and decreasing the expression of DKK-1. This stimulation induced proliferation in hDPCs and upregulated the expression of the Wnt family members 3a, 5a, and 7a at the transcript level. Additionally, Enz_MoriL suppressed JAK1 and STAT3 phosphorylation, contrasting with IFN-γ, which induced them in the catagen stage. In conclusion, Enz_MoriL directly induced signals for anagen re-entry into hDPCs by affecting the Wnt/β-catenin pathway and enhancing the production of growth factors. Furthermore, Enz_MoriL attenuated and reversed the interferon-induced AA-like environment by blocking the JAK-STAT pathway in hDPCs.

J Cosmet Dermatol 2024; 23:1638-1644. [PMID: 38247260 DOI: 10.1111/jocd.16173] [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: 09/28/2023] [Revised: 12/19/2023] [Accepted: 12/28/2023] [Indexed: 01/23/2024]
Abstract
BACKGROUND Characterized by progressive hair loss due to an excessive response to androgens, androgenetic alopecia (AGA) affects up to 50% of males and females. Minoxidil is one of approved medications for AGA but inadequate responses occur in many patients. AIMS To determine whether 1565 nm non-ablative fractional laser (NAFL) could yield better therapeutic benefits for patients with AGA as compared with 5% minoxidil. METHODS Thirty patients with AGA were enrolled; they were randomly assigned into the laser or minoxidil treatment groups. For the laser treatment group, patients were treated by 1565 nm NAFL at 10 mJ, 250 spots/cm2 with 2 weeks intervals for 4 sessions in total. For the minoxidil treatment group, 1-milliliter of topical 5% minoxidil solution was applied to hair loss area twice a day. RESULTS The primary outcomes were the changes in numerous hair growth indexes at the Week 10 as compared with the baselines. Both 1565 nm NAFL and 5% minoxidil led to significantly greater hair densities and diameters in patients at the Week 10 than the baselines (p < 0.01). As compared with 5% minoxidil, 1565 nm NAFL showed significantly greater improvements in total hair number, total hair density (hair/cm2), terminal hair number, terminal hair density (hair/cm2), number of hair follicle units, and average hair number/number of hair follicle units. CONCLUSIONS Our data demonstrate that 1565 nm NAFL exhibits superior clinical efficacy in some aspects of hair growth to the topical minoxidil. It is a safe and effective modality in treating AGA.

Abstract
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
Chemotherapy-induced alopecia (CIA) is a common and debilitating condition in children, with limited research on its characteristics and treatment. Therefore, this study aims to describe the characteristics of pediatric patients with CIA and the treatment outcomes of topical minoxidil and L-cystine, medicinal yeast, and pantothenic acid complex-based dietary supplements (CYP). This retrospective cohort study analyzed data from patients who underwent high-dose conditioning chemotherapy followed by hematopoietic stem cell transplantation and were treated with either topical minoxidil or CYP for CIA between January 2011 and January 2022. Among the 70 patients evaluated, 61 (87.1%) experienced clinical improvement. Patients in the groups with superior treatment outcomes received a greater cumulative amount of minoxidil and underwent treatment for a more extended duration (P < 0.05) than those in the other groups. All 70 (100%) patients received topical minoxidil, and 42 (60%) were administered CYP. Hair thickness was significantly higher in the combination therapy group than in the minoxidil monotherapy group (21.4% vs. 9.3%, P = 0.02). However, only 3 (4.3%) patients reported mild and self-limiting adverse events. In conclusion, our study shows that minoxidil and CYP administration represent viable treatment options for pediatric CIA.

Abstract
OBJECTIVE In this study, the safety and efficacy of scalp repair serum microneedles combined with oral drug administration and topical medication were investigated for the treatment of moderate to severe androgenetic alopecia. METHODS Twenty patients, consisting of 4 males and 16 females, who sought treatment for moderate to severe androgenetic alopecia at our hair medicine research center alopecia specialty clinic between August and December 2022 were randomly selected for the study. Male patients underwent oral administration of finasteride topical application of 5% minoxidil, and biweekly scalp repair serum microneedle therapy. Female patients were administered spironolactone or Diane-35 orally and applied 2% minoxidil topically, paired with biweekly scalp repair serum microneedle therapy sessions. After seven treatments, the scalp repair serum microneedle was discontinued, but oral administration and topical applications were continued, followed by a 1-month follow-up. Using a hair dermoscopy, hair follicles in a fixed region on the top of the head were manually counted per unit area to evaluate the hair restoration status of the patients quantitatively. RESULTS All 20 patients completed 3 months of combined therapy and a 1-month follow-up. On average, the patients experienced an increase of 42.6 hairs, with an efficiency rate of 100%. Significant differences were observed in hair count between any two of the first seven treatments (p < 0.001). A significant negative correlation was discovered between the initial pre-treatment hair count and the total improvement of hair (p < 0.001), indicating that the greater the degree of hair loss before treatment, the more pronounced the improvement. CONCLUSION Scalp repair serum microneedle combined therapy in moderate to severe androgenetic alopecia significantly reduces the number of microneedle treatments required, enhances treatment efficacy, and improves therapeutic outcomes.

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.

Abstract
Androgenetic alopecia (AGA) is a transracial and cross-gender disease worldwide with a higher prevalence among young individuals. Traditional oral or subcutaneous injections are often used to treat AGA, however, they may cause severe side-effects and therefore effective treatments for AGA are currently lacking. In this work, to treat AGA, we developed a composite paste system based on minoxidil (MXD)-loaded nanoparticles and valproic acid (VPA) with the assistance of roller-microneedles (roller-MNs). The matrix of composite paste systems is carboxymethyl cellulose (CMC), hyaluronic acid (HA) and polyvinylpyrrolidone (PVP). The roller-MNs can create microchannels in the skin to enhance drug transdermal efficiency. With the combined effects of the stimulation hair follicle (HF) regrowth by upregulating Wnt/beta-catenin of VPA and the mechanical microchannels induced by roller-MNs, the as-prepared composite paste systems successfully boost perifollicular vascularization, and activate hair follicle stem cells, thereby inducing notably faster hair regeneration at a lower administration frequency on AGA mouse model compared with minoxidil. This approach offers several benefits, including the avoidance of efficacy loss due to the liver's first-pass effect associated with oral drug, reduction in the risk of infection from subcutaneous injection, and significant decrease in the side effects of lower-dose MXD.

Traditional Chinese Medicine Shi-Bi-Man regulates lactic acid metabolism and drives hair follicle stem cell activation to promote hair regeneration. Chin Med 2023; 18:84.

Abstract
BACKGROUND As a supplement for promoting hair health, Shi-Bi-Man (SBM) is a prescription comprising various traditional Chinese medicines. Though SBM has been reported to promote hair regeneration, its molecular mechanism remains unclear. Cynomolgus monkeys (Macaca fascicularis) are non-human primates with a gene expression profile similar to that of humans. The purpose of this research is to evaluate the effect of SBM on promoting hair regeneration in cynomolgus monkeys and to reveal the underlying mechanism. METHODS The effect of SBM on hair regeneration was observed by skin administration on 6 cynomolgus monkeys with artificial back shaving. The molecular mechanism of SBM was studied using single-cell RNA sequencing (scRNA-seq) in combination with quantitative polymerase chain reaction (qPCR) detection for gene transcription level, and immunofluorescence staining verification for protein level. RESULTS SBM significantly induced hair regeneration in cynomolgus monkeys, increased hair follicle number and facilitated hair follicle development. ScRNA-seq revealed an increase in the number of hair follicle stem cells (HFSCs) with a higher activation state, as evidenced by the higher expression of activation marker LDHA related to metabolism and the proliferation marker MKI67. Immunofluorescence analysis at the protein level and qPCR at the mRNA level confirmed the sequencing data. Cellchat analysis revealed an enrichment of ligand-receptor pairs involved in intercellular communication in Laminin-related pathways. CONCLUSION SBM significantly promotes hair regeneration in cynomolgus monkeys. Mechanically, SBM can up-regulate LDHA-mediated lactic acid metabolism and drive HFSC activation, which in turn promotes the proliferation and differentiation of HFSCs.

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
Ectodysplasin A (EDA) signaling is initially identified as morphogenic signaling regulating the formation of skin appendages including teeth, hair follicles, exocrine glands in mammals, feathers in birds and scales in fish. Gene mutation in EDA signaling causes hypohidrotic ectodermal dysplasia (HED), a congenital hereditary disease with malformation of skin appendages. Interestingly, emerging evidence suggests that EDA and its receptors can modulate the proliferation, apoptosis, differentiation and migration of cancer cells, and thus may regulate tumorigenesis and cancer progression. More recently, as a newly discovered hepatocyte factor, EDA pathway has been demonstrated to be involved in the pathogenesis of nonalcoholic fatty liver disease (NAFLD) and type II diabetes by regulating glucose and lipid metabolism. In this review, we summarize the function of EDA signaling from skin appendage development to multiple other diseases, and discuss the clinical application of recombinant EDA protein as well as other potential targets for disease intervention.

Abstract
Pediatric hair loss is a cause of concern for patients and families. Early diagnosis and treatment are crucial, as delays in care for certain diagnoses can cause permanent scarring alopecia. The evaluation of hair loss includes a thorough history, physical examination, and other potential tests. The causes of hair loss can be classified as either acquired versus congenital. Acquired causes of hair loss can be subdivided into scarring and nonscarring; however, some conditions may present as nonscarring and progress to scarring alopecia. Recommendations for the evaluation and treatment of pediatric hair loss for the primary care practitioner will be summarized.

Abstract
AIM Female pattern hair loss (FPHL) is a common condition that is influenced by many external and internal factors. We aimed to identify the prevalence of FPHL among secondary school girls and identify possible associated factors. METHODS FPHL among 3405 adolescent females was identified using detailed history, physical examination, and dermoscopy in this cross-sectional study. RESULTS Among the 3405 included students, 2430 (71.4%) had no FPHL and 975 (28.6%) were diagnosed with FPHL (p = 0.001). The mean age of girls with FPHL was 16.43 ± 1.10 and ranged between 15 and 18 years. Among those with FPHL, 427 (43.8%) attended urban schools while 548 (56.2%) attended rural schools. No significant differences regarding paternal and maternal education, family income, or parental degree of education were observed among those with FPHL and those without (p = 0.230; p = 0.063; p = 0.276, respectively). CONCLUSION FPHL had an overall prevalence of 28.6% among secondary school girls with a significant predominance in rural over urban areas and with a significantly associated family history. Irregular menses, history of thyroid disease, and hirsutism were significant predictors for FPHL.

Abstract
Hair loss and thinning are possible complications in those undergoing endocrine therapies with aromatase inhibitors. Alopecia in pediatric patients undergoing endocrine therapy has not been previously reported. We describe two adolescents, 14 and 16 years of age, who developed androgenetic alopecia following treatment with anastrozole for idiopathic short stature. Accordingly, the possible adverse event of alopecia should be considered in the pediatric population undergoing treatment with aromatase inhibitors.
