This review found that while finasteride may improve female pattern hair loss and hirsutism in women, more long-term studies are needed to optimize its use and assess potential consequences.

This study observed that estrogen receptor β and androgen receptor expressions in the skin decline with age, more noticeably under sun exposure, suggesting a role in skin aging.

This editorial reviews recent European legal developments related to patents on second medical uses and dosage regimes, with no new research findings reported.

This review discusses the current understanding of androgen biosynthesis, mechanisms of action, and their roles in human biology, as well as related congenital and acquired disorders, but it reports no new research findings.

This study found that untreated hirsute patients have lower expression of type 2 17β-HSD mRNA in scalp hairs, indicating potential disturbances in androgen metabolism, compared to treated hirsute patients.

This study evaluated a natural, herbal-based powder formulation aimed at removing unwanted facial hair while promoting skin health, finding that the product was effective and well-suited for use based on physical properties and user feedback.

This review discusses the use of caffeine in cosmetics for its fat-reducing, antioxidant, and hair growth properties, but reports no new research findings.

This study observed that alopecia areata can be induced and serially transferred in C3H/HeJ mice using skin grafts, providing a useful model for studying the disease in humans.

This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.

This study identified a new genetic locus, ahl4, on distal Chromosome 10 that contributes to the early-onset, severe hearing loss in A/J mice compared to B6 mice.

This study found that liposomes coated with cationic polymers, chitosan and Eudragit EPO, showed improved physicochemical stability and enhanced skin diffusion of aciclovir and minoxidil compared to uncoated liposomes.

This study reports that C3H/HeJ mice and DEBR rats serve as effective models for screening potential treatments for human alopecia areata, despite certain challenges in predictability and cost.

This review discusses the roles of immune responses and cells in skin health and disease, emphasizing recent insights into their mechanisms and potential therapeutic applications, but presents no new experimental results.

This study found that cyclosporin A treatment enhances hair growth in mice by inhibiting calcineurin-NFAT1 activity, which alters keratinocyte differentiation and apoptosis-related gene expression in hair follicles.

This review discusses current and potential treatments for alopecia areata, focusing on immunosuppressive and immunomodulatory approaches, but provides no new clinical results.

This study showed that in C3H/HeJ mice, focal follicular inflammation starts before overt hair loss, with inflammation severity possibly reaching a threshold causing hair follicle dystrophy prior to visible hair loss.

This article reviews potential animal models for studying androgenetic alopecia and reports no new experimental results; the authors highlight the need for further development of rodent models.

In this study, mixing mouse epithelial and dermal cells was the most successful method for reconstituting hair follicles in mice, with the hair patch assay providing the quickest results.

This review discusses recent advances in understanding the pathogenesis of autoimmune alopecia areata and reports no new clinical results; it highlights potential for developing more effective treatments.

This study found that recombinant hepatitis B vaccine may increase the risk of alopecia areata onset in older predisposed mice but larger trials suggest this effect might lie within normal variation.

This review discusses rodent models of alopecia areata and suggests they are crucial for understanding the autoimmune mechanisms and potential treatments but reports no new clinical results.

This article reviews insights into the pathogenesis of primary cicatricial alopecias, such as lichen planopilaris, provided by emerging technologies, but it does not report new clinical results.

This study found that mechlorethamine restored hair growth in mice with alopecia-areata-like disease by eliminating infiltrated lymphocytes and inhibiting certain pro-inflammatory cytokines in treated skin areas.

This study found that anthralin and mechlorethamine were the most effective therapies among those tested in AA-affected rodent models, providing a basis for further analysis of their mechanisms in Alopecia Areata.

This study found that defective cross-linking in hair cuticles is observable in a minority of mouse hair mutants, suggesting different proteins are involved in cross-linking across cell types.

This study found that injecting interferon gamma into C3H/HeJ mice did not alter the frequency or onset of alopecia areata, suggesting the protein alone does not trigger the disease.

This study found hair regrowth in the majority of AA-affected mice and rats treated with diphencyprone, suggesting its potential utility for understanding human alopecia areata and the drug's therapeutic action.

In this study, researchers identified gremilin-2 as a highly specific gene to the dermal sheath cup, suggesting it plays a key role in maintaining its properties.

Hair transplant complications were likely due to deep graft placement and rough handling.

In this study, Makarova et al. found that topical vitamin D3 significantly delayed basal cell carcinoma development in UVR-exposed, BCC-prone mice, while oral vitamin D3 supplements did not prevent carcinogenesis, suggesting a potential role of UV-induced vitamin D3 in inhibiting tumor growth.
