Abstract
BACKGROUND Patients with androgenetic alopecia experience a significant decrease in self-esteem and quality of life. There are several methods by which these factors may be improved. AIMS Determining whether patients feel better about themselves with a better quality of life after undergoing hair transplant procedure. PATIENTS/METHODS 35 people were chosen from Jordan Skin and Hair Clinic in Tehran, Iran. Following hair transplant, follow-up subjects had their quality of life and level of self-esteem assessed using the Rosenberg Self-Esteem Scale (RSES) and Dermatology Life Quality Index (DLQI), respectively. The means of quantitative results were compared using paired T-test. The chi-square test was done to compare preoperative and postoperative characteristics qualitatively. Differences were regarded significant if p < 0.05. Analysis of covariance was applied to evaluate the effect of marital status and educational level on outcome variables (ANCOVA). RESULTS Our findings showed a statistically significant difference (p < 0.001) between pre- and post-operative hair transplantation for quality of life, and mean score increased to 2.17. There was a statistically significant difference between the two groups, with an average self-esteem score on RSES rising to 5.35 (p < 0.001). A statistically significant link between educational achievement and quality of life was found (p < 0.001). CONCLUSION This study found postoperative psychological aspects of AGA patients significantly improve than preoperative. Our results show that there is a statistically significant difference between the self-esteem and quality of life of AGA patients before and after hair restoration surgery.

Anti-Alopecia Activity of Alkaloids Group from Noni Fruit against Dihydrotestosterone-Induced Male Rabbits and Its Molecular Mechanism: In Vivo and In Silico Studies. Pharmaceuticals (Basel) 2022; 15:ph15121557. [PMID: 36559008 PMCID: PMC9784383 DOI: 10.3390/ph15121557] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 12/10/2022] [Accepted: 12/11/2022] [Indexed: 12/15/2022] Open
Abstract
Androgenic alopecia (AA) is a condition that most commonly affects adult men and is caused by an increase in the hormone dihydrotestosterone (DHT) in the hair follicles. Anti-alopecia drugs should be discovered for hair follicles to enter the anagen growth phase. Therefore, this study evaluated the hair growth-promoting activity of Noni fruit’s water, ethyl acetate, n-hexane fractions, and sub-fractions from the active fraction in the alopecia male white rabbit model. The Matias method was modified by inducing rabbits using DHT for 17 days, followed by topical application of Noni fruit solution for 21 days. Meanwhile, hair growth was evaluated by histological observation of the follicular density and the anagen/telogen (A/T) ratio in skin tissue. In the first stage, five groups of male white rabbits were studied to obtain the active fraction; DHT+Minoxidil as standard, DHT+vehicle (NaCMC 1%), DHT+FW, DHT+FEA, and DHT+FH. The FEA as the active fraction was followed by open-column chromatography separation (DCM:Methanol) with a gradient of 10% to produce sub-fractions. In the second stage, the six main sub-fraction groups of male rabbits studied were DHT+FEA-1 to DHT+FEA-6. The follicular density of groups FEA-3 was 78.00 ± 1.52 compared with 31.55 ± 1.64 and 80.12 ± 1.02 in the Vehicle and Minoxidil groups. Additionally, group FEA-3 showed large numbers of anagen follicles with an A/T ratio of 1.64/1 compared to the vehicle group of 1/1.50 and 1.39/1 for Minoxidil control. Group FEA-3 was identified by LC-MS/MS-QTOF, followed by molecular docking to the androgen receptor (PDB: 4K7A), causing alopecia. The results showed that three alkaloid compounds with skeleton piperazine and piperidine, namely (compounds 2 (−4.99 Kcal/mol), 3 (−4.60 Kcal/mol), and 4 (−4.57 Kcal/mol)) had a binding affinity similar to Minoxidil, with also has alkaloid skeleton piperidine−pyrimidine (−4.83 Kcal/mol). The dynamic behavior showed the stability of all androgen receptor compounds with good RMSD, SMSF, and SASA values after being studied with 100 ns molecular dynamics (MD) simulations. This study produced a common thread in discovering a class of alkaloid compounds as inhibitors of androgen receptors that cause alopecia.

Abstract
BACKGROUND Hair loss causes significant psychosocial distress to patients. Health utility measurements offer an objective, quantitative assessment of health-related quality of life (QOL). METHODS We performed a prospective cohort study on patients with hair loss between January 1, 2018 and December 31, 2020. Patient metrics were compared with layperson perception of alopecia, prospectively collected between August 1 and December 31, 2017. Health utility measures were quantified using the visual analog scale (VAS), standard gamble (SG), and time trade-off (TTO) in quality-adjusted life-years (QALYs) and relative to the minimal clinically important difference (MCID). Bonferroni correction to the significance threshold was performed. RESULTS Thirty-one patients with alopecia were compared with 237 laypeople. Patient metrics for female hair loss were all significantly lower than laypeople measures (VAS QALYs 0.65 ± 0.21 vs. 0.83 ± 0.18, p = 0.0001). Mean SG QALYs were lower for patients in the male alopecia state (0.86 ± 0.23 vs. 0.96 ± 0.12, p = 0.0278). Post-hair transplant improvement in TTO was significantly greater for patients (+ 0.08 ± 0.12 vs. + 0.02 ± 0.09, p = 0.0070) and significantly more often exceeded the MCID (45.2% vs. 16.9%, p = 0.0006). CONCLUSIONS Alopecia negatively impacts QOL, and the true patient experience is more taxing than what is perceived by laypeople. Hair transplantation improves QOL more for male patients than common perception. LEVEL OF EVIDENCE IV This journal requires that authors assign a level of evidence to each article.

Abstract
Hair follicle stem cells (HFSCs) are among the most widely available resources and most frequently approved model systems used for studying adult stem cells. HFSCs are particularly useful because of their self-renewal and differentiation properties. Additionally, the cyclic growth of hair follicles is driven by HFSCs. There are high expectations for the use of HFSCs as favourable systems for studying the molecular mechanisms that contribute to HFSC identification and can be applied to hair loss therapy, such as the activation or regeneration of hair follicles, and to the generation of hair using a tissue-engineering strategy. A variety of molecules are involved in the networks that critically regulate the fate of HFSCs, such as factors in hair follicle growth and development (in the Wnt pathway, Sonic hedgehog pathway, Notch pathway, and BMP pathway), and that suppress apoptotic cues (the apoptosis pathway). Here, we review the life cycle, biomarkers and functions of HFSCs, concluding with a summary of the signalling pathways involved in HFSC fate for promoting better understanding of the pathophysiological changes in the HFSC niche. Importantly, we highlight the potential mechanisms underlying the therapeutic targets involved in pathways associated with the treatment of hair loss and other disorders of skin and hair, including alopecia, skin cancer, skin inflammation, and skin wound healing.

Abstract
Hair loss is a prevalent medical condition affecting both genders. In this study, we investigate the effects of a specific class of extracellular vesicles (EVs), namely human normal fibroblast-derived EVs (hFB-EVs), on human dermal papilla (DP) and outer root sheath (ORS) cells and examine the molecular mechanisms responsible for hair growth in hair follicles (HFs). We find that Wnt3a, which maintains the hair-generating activity of DP cells, is enriched and more strongly associated with hFB-EVs than with fibroblasts. Furthermore, hFB-EV-associated Wnt3a mediated receptor activation in cultured DP cells, leading to an increase in β-catenin in the cytoplasm and its translocation into the nucleus, thereby elevating expression of the target genes Axin2 and Lef1. Additionally, hFB-EVs promoted the migration, proliferation, and differentiation of ORS cells and elongation of the hair shaft in human HFs. These findings revealed a novel mechanism by which hFB-EVs influence hair growth.

Abstract
Caffeine, particularly after ingestion, is well known to exert various pharmacological effects. A growing body of evidence implicates the ingestion of caffeine with beneficial effects on several diseases. The easy penetration of caffeine across the skin barrier and into human skin makes caffeine an ideal compound for topical application. Hair loss is known to negatively affect the quality of life and predispose to depression and anxiety. Androgenetic alopecia (AGA) is the most common type of hair loss in both men and women. To date, only few approved drug-based treatments for AGA exist, and these are inevitably associated with side effects. Therefore, the development of topical treatments based on well-tolerated natural ingredients such as caffeine to alleviate hair loss may provide a much-needed alternative to drug-based approaches.

Abstract
Today, about 50% of men and 15-30% of women suffer from hair loss as well as the associated psychological impact. Drug therapy, especially through topical administration, is the main treatment strategy for stimulating hair regrowth. However, challenges exist due to the skin barrier that hinders drug penetration. To this end, many efforts have been made to enhance drug penetration efficiency. This review focuses on the advancement of the transdermal drug delivery strategies for hair loss therapy reported in the last five years, especially those via nanoformulations for topical administration and microneedles for transdermal delivery. In addition, physical or chemical penetration enhancers are also introduced, which are often applied with the drug delivery systems to achieve a synergy effect.

Abstract
Importance Androgenetic alopecia is a highly prevalent condition across both sexes and can be surgically corrected through hair transplant. Health utility scores, which represent quantitative estimates of individual preferences for a given state of health, are a measure of health-related quality of life. The health utility scores for sex-specific alopecia and the posttransplant state have not previously been quantified. Objective To obtain health utility measurements for the objective assessment of sex-specific alopecia and hair transplant surgery and to analyze layperson perception of alopecia compared with other chronic health conditions. Design, Setting, and Participants A prospective clinical study was conducted from August 1 to December 31, 2017, at the Harvard Decision Science Laboratory. Adult casual observers (n = 308) completed an internet-based health utility questionnaire. Health states were presented using still patient images and a description of 5 health states, including monocular blindness, binocular blindness, male alopecia, female alopecia, and male posttransplant state. Main Outcomes and Measures Health utility measures of sex-specific alopecia, posttransplant state, and monocular and binocular blindness were measured by visual analog scale (VAS), standard gamble (SG), and time trade-off (TTO) in quality-adjusted life-years (QALYs). Groups were analyzed with 1-way analysis of variance and post hoc Tukey pairwise comparison. Results The 308 participants included 157 (51.0%) women with a mean (SD) age of 30.8 (13.5) years. Mean (SD) health utility measures included 0.85 (0.18) QALYs for the VAS, 0.93 (0.17) QALYs for the SG, and 0.93 (0.17) QALYs for the TTO in male alopecia; 0.83 (0.19) QALYs for the VAS, 0.92 (0.17) QALYs for the SG, and 0.91 (0.18) QALYs for the TTO in female alopecia; and 0.93 (0.11) QALYs for the VAS, 0.95 (0.15) QALYs for the SG, and 0.95 (0.16) QALYs for the TTO in a man in the posttransplant state. The mean (SD) health utility of monocular blindness was 0.76 (0.17) QALYs for the VAS, 0.87 (0.21) QALYs for the SG, and 0.86 (0.20) QALYs for the TTO. The health utility score for the posttransplant state was significantly improved compared with the health utility score for alopecia in both sexes (female VAS: +0.10 [95% CI, 0.06-0.14; P < .001]; male VAS, +0.08 [95% CI, 0.04-0.12; P < .001]). Hair loss in women and men demonstrated significantly lower QALYs on the VAS compared with the posttransplant state (female: -0.10 [95% CI, -0.14 to -0.06; P < .001]; male: -0.08 [95% CI, -0.12 to -0.04; P < .001]). Conclusions and Relevance Alopecia has a meaningful negative influence on health utility measures in both sexes. Hair transplant surgery significantly increases health utility measures compared with untreated alopecia in both sexes as rated among layperson observers. Level of Evidence NA.

Abstract
INTRODUCTION Androgenetic alopecia (AGA) is a benign condition with variable psychosocial impact, with some individuals adapting well while others needing therapeutic support. Although 5α-reductase inhibitors like finasteride and dutasteride have proven effective in ameliorating AGA, their use/selection is currently a subject of debate. AREAS COVERED Treatment of AGA with 5α-reductase inhibitors lead to variable adverse effects and relatively unstable results (therapeutic efficacy ending with treatment cessation), so the choice of optimal therapy is not straightforward. This paper presents a general perspective regarding AGA based on studies listed in PubMed, to better understand/appreciate the opportunity for long term use of medication for a biological condition having non-life threatening implications. Studies focussed on adverse effects suggest that finasteride should be used with caution in AGA, due to considerable and persistent side effects induced in some men. In contrast, efficacy data indicate that dutasteride (a stronger inhibitor) presents superior therapeutic results compared to finasteride. EXPERT OPINION This paper argues that finasteride should be preferred to dutasteride in the treatment of AGA. Thus, finasteride preserves important physiological roles of dihydrotestosterone (unrelated to AGA) and, in addition, its adverse effects seem to be (at least in part) predictable.
