This study found that waving virgin human hair with thioglycerol at pH 9.0 using ammonia solution caused less damage than using thioglycolic acid, while maintaining good waving efficiency.

This study found that Hordenine promotes hair regrowth and enhances dermal-papilla cell activity in mice by activating the Wnt/β-catenin signaling pathway, suggesting potential for treating alopecia.

In this study, researchers found that androgen receptor expression and AKR1C-mediated androgen inactivation, including AKR1C4, are prominent in scalp sebaceous glands, with AKR1C expression decreasing with age and differing by sex, suggesting these changes may impact hair follicle health as people age.

In this study, synthetic vitamin D3 analogs stimulated hair growth and formation of normal hair follicles in nude mice, unlike the natural form 1,25 dihydroxyvitamin D3.

In this study, Cyanidin 3-O-arabinoside was found to protect against DHT-induced dermal papilla cell senescence and mitochondrial dysfunction in androgenetic alopecia, restoring hair growth in mouse models.

Antiandrogen therapy may be beneficial for women with hidradenitis suppurativa.

In this study, Derma Genie™-H001 was shown to reduce inflammation, counteract oxidative and UVB-induced damage, and support hair growth-related gene expression in human dermal papilla cells, suggesting its potential as a functional cosmetic ingredient to alleviate hair loss symptoms.

This study found that the absence of Hes1 in hair follicles delays secondary hair germ activation and shortens the anagen phase, impacting HFSC self-renewal and long-term hair regeneration.

This study found that Dab2 conditional knockout mice experienced delayed hair follicle cycles and reduced hair follicle stem cell activity, suggesting Dab2's crucial role in regulating stem cell activation and anti-aging process in hair follicles.

This study reported that black hairy tongue can occur after allogeneic stem cell transplantation and may indicate cutaneous graft-versus-host disease, highlighting the need for histopathologic evaluation.

This article reviews the clinical and biochemical features of genetic mutations affecting dihydrotestosterone production and their potential role in male pseudo-hermaphroditism, but presents no new clinical results.

HGF activator helps convert HGF to its active form, promoting hair growth.

Finasteride significantly reduces DHT levels in male dogs without affecting testosterone levels, suggesting it could be used to treat benign prostatic hypertrophy in dogs weighing 10 to 50 kilograms.

This study successfully established an immortalized human dermal papilla cell line that maintains characteristics of original cells without malignant transformation, potentially benefiting hair research.

This study found that mutations in exon 3 of the hr gene are strongly associated with congenital hypotrichosis in Valle del Belice sheep, suggesting a potential genetic link to the disorder.

In this mouse study, topical 1,25-dihydroxyvitamin D3 protected against cyclophosphamide-induced hair loss and inhibited mammary tumor growth, with effects varying by sex and tumor presence.

In this study using lab models, YangHyulEum Gami-Bang (YHEG) was associated with promoting hair growth and inhibiting factors that contribute to hair loss.

This study identified "HTLV-1-associated lichenoid dermatitis" as a skin condition in HTLV-1-infected individuals, characterized by reactive eruptions associated with increased immunity toward infected CD4+ T cells.

This review discusses the enzyme levels involved in dihydrotestosterone formation in androgenetic alopecia patients and reports no new results; the authors suggest these differences may lead to better treatments for men and women.

This study found that the total testosterone/dihydrotestosterone ratio correlates with a negative metabolic profile in both women with PCOS and healthy women.

Prostaglandin D2, found in higher levels in bald scalps, stops hair growth and could be a target for treating hair loss.

This document provides protocols for gender-affirming hormone therapy in India, highlighting the need for research on outcomes and adverse events in adults receiving such therapy; it reports no new results.

This study found that the dehydroepiandrosterone hydroxylating enzyme system in hair follicles is similar to the liver monooxygenase system, sharing characteristics such as inhibition by carbon monoxide and dependency on NADPH.

This study found that the androgen precursors DHEA and androstenedione stimulated androgen-sensitive parameters in the sebaceous glands of the skin in castrated male hamsters.

This review highlights the dermatological needs of transgender and gender diverse individuals in Australia, emphasizing the role of dermatologists in managing skin and hair conditions related to gender affirmation and hormone therapy.

In this study, the authors identified the DHRS9 SNP rs72623193 as most significantly associated with response to dutasteride in treating male pattern hair loss, with additional variants potentially contributing.

This study found that the truncated hHb1-DeltaN transcript in breast cancer cells is produced by a cryptic intron promoter and responds to DNA demethylation, potentially altering cancer cell adhesion.

This study reports that transdermal exposure to owners' topical hormone replacement therapy caused alopecia in six dogs, but the condition resolved after the therapy was discontinued.

This study found that mice lacking the Vitamin D receptor showed disrupted hair follicle cycling, which was partially restored with hedgehog signaling pathway activation, suggesting a role for this pathway in follicle regulation independent of vitamin D.

This article suggests that testosterone therapy might be considered if other treatments fail, but emphasizes discussing potential risks and benefits with patients before prescribing.
