This study found that minoxidil did not significantly increase hair shaft elongation in ex vivo human hair follicle culture, questioning the suitability of this method for studying its hair-growth-promoting effects.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

This study found that the loss of Smad4 in keratinocytes reduces Dsg4 expression via disrupted BMP signaling, contributing to hair follicle degeneration and alopecia.

This review discusses recent advances in the genetic understanding of inherited hair and nail disorders and reports no new clinical results.

In this study, researchers identified three molecules in hair that varied with age, suggesting potential markers for aging and targets for cosmetic products.

This study found that deleting the Hes1 gene disrupts hair regeneration by delaying anagen initiation and shortening the anagen phase, suggesting it's crucial for maintaining hair cycle homeostasis.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

This study found that Wnt ligands from CD133-positive dermal papilla cells are essential for maintaining hair growth by supporting cell signaling between different hair follicle structures.

This study found that doxorubicin induces hair follicle apoptosis through TRAIL receptor signaling, providing insights for managing chemotherapy-induced hair loss.

This study identified a missense mutation in the keratin 71 gene as the cause of autosomal dominant woolly hair/hypotrichosis in a Japanese family, marking the first human mutation in KRT71 linked to a hair disorder.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

This study found that TRH modulates specific keratins in human scalp tissue, suggesting its potential influence on hair growth and the need for further exploration of neuroendocrine controls in keratin expression.

This review highlights recent genetic research advancements in understanding hereditary hair diseases but reports no new study results, emphasizing the identification of genes related to both monogenic and polygenic hair disorders.

This study found that mutations in the Sgk3 gene cause defective hair follicle development and altered hair cycling in mice, with variable phenotypic outcomes depending on different dysfunction patterns of the SGK3 protein.

In this study, a mixture of tocopherol acetate, L-menthol, and stevioside was more effective in promoting hair growth in mice compared to tocopherol acetate or L-menthol alone.

This article reviews practical approaches for managing dermatologic conditions in patients with skin of color and reports no new clinical findings.

This study identified differentially expressed proteins and pathways potentially involved in wool bending in Zhongwei goats, with specific genes like COL6A1 and CRNN emerging as important candidates in this process.

In this study, fermented herbal extracts promoted hair growth and activated Wnt signaling more effectively than nonfermented extracts in mice, suggesting potential benefits for hair regrowth.

In this study, sodium thiosulfate was observed to promote hair growth in mice by encouraging hair follicles to enter the growth phase and complementing the effects of minoxidil, suggesting potential benefits for hair loss treatment.

This review discusses various noninflammatory alopecias in horses, particularly alopecia areata, and reports no new treatment results, emphasizing the need for differential diagnosis through examination and biopsy.
