This study found that NFI-C plays a crucial role in the transition from the telogen to anagen phase of the hair follicle cycle, affecting hair growth initiation in mice.

This study found that type 2 immunity, especially involving ILC2 cells, helps maintain skin homeostasis by regulating the proliferation and community stability of hair follicle epithelial cells in the presence of Demodex mites.

This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

This article discusses the structure of the human type II 5 alpha-reductase gene and reports no new experimental results.

This study suggests that finasteride's effect on promoting hair growth in men with androgenetic alopecia may be due to its inhibition of 5aR2 localized in hair follicles.

This study details the isolation and characterization of the human type II 5 alpha-reductase gene, which may play a role in male pseudohermaphroditism, prostate cancer, and benign prostatic hyperplasia.

This study identifies six novel keratin genes from the chromosome 17q21.2 region, suggesting their association with hair follicles, while all 27 keratin genes in the domain have been characterized transcriptionally.

This study found that the prevalence of androgenetic alopecia in Chinese men was lower than in Caucasian men, similar to Korean men, and most commonly presented as type III vertex.

This background review discusses alopecia areata, highlighting the role of CD8+NKG2D+ T cells in hair follicle pathogenesis, and notes that the exact mechanisms causing hair loss remain unclear.

This study identified LY191704 as a specific noncompetitive inhibitor of human 5 alpha-reductase type 1, which may be useful in treating endocrine disorders related to DHT overproduction.

This study demonstrated the expression of type 1 interferon-related proteins in inflammatory lesions of alopecia areata, showing a distinct distribution pattern compared to cicatricial alopecia.

This study found that hyperandrogenemia in Chinese women with PCOS is associated with higher risks of type 2 diabetes and obesity, suggesting it should be prioritized in managing PCOS-related infertility.

In this review, researchers explored the roles of vitamins A, B3, C, D, and E in skin immunity, highlighting their potential as therapeutics for skin diseases due to their antioxidant, anti-inflammatory, and antimicrobial properties.

This review discusses low-level light therapy for androgenetic alopecia and female pattern hair loss, noting minimal clinical evidence on its efficacy and the need for more controlled studies.

This study found that vitamin C increased the survival, proliferation, and hair-regenerative potential of adipose-derived stem cells through the MAPK pathway and enhanced hair growth in mice.

This case report documents a reversible instance of complete body hair loss (alopecia universalis) in a patient undergoing chronic hepatitis C treatment with pegylated interferon alpha-2b and ribavirin, with hair regrowth observed within three months after therapy completion.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

This study identified a distinct gene near the hairless locus on chromosome 8p that is responsible for hereditary Marie Unna type hypotrichosis in a German family.

This study reported that while lichen planus was not significantly linked to hepatitis C virus infection, pruritus, dry skin, and hair loss were more common in HCV patients post-interferon treatment.

In this study, procyanidin B-2 and C-1 were found to promote hair growth by selectively inhibiting protein kinase C, supporting their potential use for hair-growing activity.

Clinical studies reported that finasteride reduces scalp dihydrotestosterone levels and improves hair growth in men with androgenetic alopecia, supporting its role as a treatment option.

This study concluded that men with benign prostatic hyperplasia receiving steroid 5α-reductase inhibitors, such as dutasteride or finasteride, have a higher risk of developing new onset type 2 diabetes compared to those taking tamsulosin.

This study found that exercise decreases the expression of 5αR1, thereby enhancing the PI3K/AKT signaling pathway in PCOS rats.

This review discusses the complex links between polycystic ovary syndrome, insulin resistance, and potential metabolic risks starting in adolescence, noting the need for early screening and treatment but reports no new clinical results.

This study found that the VEGF +405G/C polymorphism may be an inheritable risk factor for polycystic ovary syndrome in south Indian women.

This study found that overexpression of the transcription factor NFIC may enhance the proliferation and differentiation of stem cells from the apical papilla, suggesting its potential role in dentin/root regeneration.

This study found that patients with myotonic dystrophy type 1 had higher numbers of nevi, dysplastic nevi, melanomas, and pilomatrixomas compared to age- and sex-matched controls.

In this study, fraction No. 3 of Oryza sativa bran extract demonstrated high unsaturated fatty acid content and significant 5α-reductase inhibition, suggesting potential for developing anti-androgenic alopecia products.

In this study, osthenol was identified as a highly potent inhibitor of 5alpha-reductase type I in LNCaP cells, significantly outperforming finasteride.

This study found that GI198745 acts as a time-dependent inhibitor of rat 5α-reductase type 2 but a rapid-equilibrium inhibitor of type 1, potentially making it more effective than finasteride in preventing rat prostate growth.
