Lichen planopilaris is a rare, chronic condition causing hair loss, mainly in middle-aged women, and early treatment is important to prevent permanent baldness.

This article discusses cicatricial alopecias, focusing on diagnosis and management strategies, but reports no new clinical findings.

Repetin is a protein involved in skin and hair development, binding calcium and compensating for other proteins when needed.

This study found HLA and beta 2-microglobulin antigens in various skin structures, with specific localization patterns in keratinocytes and hair follicle components, but not in eccrine or apocrine glands.

This study describes five patients with porokeratotic adnexal ostial nevus, a rare skin disorder, highlighting its clinical features and proposing a new encompassing term for related conditions.

This study found that scalp involvement in dermatomyositis consistently shows a nonscarring pattern with chronic telogen effluvium, featuring telangiectasia and mucin deposition as universal histologic markers.

This study found that hair follicle stem cells are stiff with high actomyosin contractility, while hair germ progenitors are soft and enlarge during quiescence, influencing hair regeneration; inducing miR-205 reduces contractility and activates regeneration in mice.

This study found that finasteride may affect Ca 2+ signalling in human sperm by interacting with the PGE 1 -binding site, but its impact on fertilization requires further investigation.

This study observed that in mouse fetuses, reticular contraction by actomyosin is involved in dermal regeneration, and differences in actin and α-SMA localization may determine the switch between regeneration and scar formation, suggesting potential insights for wound regeneration therapy.

This study found that inducing miR-205 reduces actin contractility and stiffness in hair follicle stem cells and progenitors, stimulating hair regeneration in both young and old mice.

This study found that actomyosin contractility in suprabasal keratinocytes influences the proliferation and differentiation of epidermal stem/progenitor cells by acting as a niche element in the skin.

Activating Wnt in skin cells controls the number of hair follicles by directing cell movement and fate.

This study observed that Langerhans cells and melanocytes migrated to hair follicle sites during human embryogenesis, suggesting that Langerhans cells acquire immunoregulatory properties there.

This case report describes successful CO2 ablation treatment of porokeratotic adnexal ostial nevus in an 8-year-old boy, with marked improvement over a 12-year follow-up.

This review provides information on the biological activity and chemical composition of various Rumex species, finding that some have pharmacological potential, but reports no new experimental results.

This report discusses two cases of porokeratotic eccrine ostial and dermal duct nevus and porokeratotic eccrine and hair follicle nevus, suggesting they may represent a single clinical entity, but reports no therapeutic outcomes.

This study suggests that while alopecia areata presents similarly across different skin tones, hair loss may be underestimated in individuals with more tightly coiled hair without a comprehensive examination, highlighting the need for culturally sensitive evaluation approaches, particularly for Black women.

The skin acts like an endocrine organ, making hormones that affect skin diseases and respond to stress.

In this study conducted across five health centers in Morocco, researchers found that factors like younger age, lower income, lack of prenatal care, and coffee consumption were associated with higher anemia risk in pregnant women; iron supplementation and antenatal care significantly reduced this risk.

Cataract surgery guidelines vary across Europe, and generic finasteride sales for hair loss have grown due to pill splitting.

This study documents that trichohyalin acts as a multi-functional cross-bridging protein in the inner root sheath of mouse hair follicles, enhancing mechanical strength by linking keratin filaments to the cell envelope.

This study suggests that Notch1 acts as a key signal in skin epithelium, promoting immune cell recruitment and aiding in normal skin repair after damage.

This study found that Hairless (Hr) acts as a corepressor of the vitamin D receptor (VDR) in human keratinocytes, blocking the action of vitamin D on keratinocyte differentiation.

This study found that PDGF-D acts as a potent mitogenic factor in adipose-derived stem cells, enhancing their proliferation, migration, and growth factor expression, suggesting its use as a preconditioning agent for ASC transplantation.

This review explores the diverse roles and heterogeneity of fibroblasts across different organs, highlighting their potential involvement in both normal tissue functioning and fibrotic diseases, but reports no new experimental results.

This study demonstrated that FGF5s acts as an inhibitor of FGF5 in regulating hair growth cycles in cashmere goat dermal papilla cells.

This study found that leptin acts as an inducer of the anagen phase in hair follicles, suggesting its role as a potential player in hair biology.

This study found that epitestosterone acts as a weak antiandrogen by inhibiting receptor binding and 5α-reductase activity in animal models.

This study found that α-MSH acts as a modulator of inflammatory and fibrogenic responses in human fibroblastic skin cells, indicating potential therapeutic options for fibrotic skin disorders and inflammatory diseases of the hair follicle.

This study found that the protein hairless acts as both a corepressor and coactivator of the vitamin D receptor, influencing gene transcription in a ligand-selective manner.
