This review discusses the potential role of extracellular vesicles in modulating hair follicle dynamics and reports no new clinical results; future investigations may inform treatment strategies for skin disorders.

This study found that while genetic variants contribute minimally to predicting hair greying in a Polish population, age remains the primary predictor, underscoring the complexity of hair greying as a genetic trait.

This study found that fibroin/gelatin and spidroin microparticles increased re-epithelialization rates and inhibited scar formation in mouse models of deep skin wounds.

This study identified key long non-coding RNAs and mRNAs involved in primary wool follicle induction in carpet wool sheep, emphasizing their roles in hair follicle development and skin processes.

Overexpression of certain genes can shorten hair by disrupting the hair-growth cycle.

In this study, a methanol extract of Eclipta alba was found to have dose-dependent hair growth-promoting activity in C57BL6 mice.

This study indicated that abnormal Bmp signaling in β-catenin gain-of-function mutants is associated with anorectal malformations, shedding light on potential mechanisms underlying these congenital conditions.

This study found that white hair exhibits increased expression of genes and proteins linked to active hair growth compared to black hair, suggesting that hair greying is associated with enhanced hair growth activity.

This study found that red light accelerated the transition from the resting to growth phase in hair follicles faster than green and blue light in mice, suggesting it may stimulate hair growth.

This study found that radiofrequency treatment, with or without hydrolyzed collagen, increased dermis thickness, neocollagenesis, and FGF2 overexpression in rat skin tissue.

This study found that STAT5 activation in the dermal papilla acts as a key switch to trigger anagen entry in postdevelopmental hair follicle cycling.

This study suggests that the period from birth to 6 months is optimal for regulating secondary hair follicle development in cashmere goats, with specific growth factors potentially playing a regulatory role.

This study found that in Chinese goat breeds, specific genetic variations, particularly in Tibetan Cashmere goats, are associated with traits like hair growth and adaptation to high-altitude environments.

This study found that chitosan and surface-deacetylated chitin nanofibrils promoted hair growth in mice and increased fibroblast growth factor-7 production in human follicle dermal papilla cells.

This article reviews the cellular dynamics affecting dermal papilla size in androgenetic alopecia and suggests targeting DP size could improve therapies, but it presents no new clinical data.

This study found that arachidonic acid may promote hair growth by enhancing dermal papilla cell function and stimulating the anagen phase in C57BL/6 mice.

In this study, forced expression of the transcription factor cDermo-1 in chicken dermis led to the formation of ectopic feather buds and enhanced feather growth, demonstrating its role in initiating skin appendage development.

This study found that Morus alba root extract activates β-catenin in hair follicle dermal papilla cells, promoting the transition to the anagen phase and enhancing hair growth factor secretion.

This article discusses the advances in understanding wound-induced hair follicle neogenesis (WIHN) and highlights the roles of specific signaling pathways and cellular plasticity, noting no clinical results but suggesting potential areas for further research.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

This study found that ancient and modern Chinese goats share close genetic ties, originating from the Fertile Crescent, with genetic divergence influenced by China's climatic divisions.

This study suggests that M2 macrophages play a key role in promoting wound-induced hair neogenesis in mice by producing growth factors like Igf1 and Fgf2.

This review examines the growing evidence for using platelet-rich plasma in aesthetic procedures such as hair restoration and skin rejuvenation but reports no new clinical results.

This study identified three candidate genes (CORT, FGF5, and CD36) associated with cold climate adaptation in Yanbian cattle through genome resequencing and comparison with African tropical cattle.

This study found that 3-Deoxysappanchalcone may stimulate hair growth in mice by promoting proliferation of hair follicle dermal papilla cells through WNT/β-catenin and STAT signaling modulation.

This review discusses the broader roles of angiogenic factors, like VEGFs and FGFs, beyond angiogenesis, highlighting their involvement in various biological and pathological processes.

This study observed that epidermal-specific deletion of aPKCλ in mice disrupts hair follicle stem cell quiescence, leading to altered hair follicle cycling and skin anomalies.

In this study, Polygonum multiflorum Radix promoted hair growth in mice, with oral administration being more effective, likely through FGF-7, while topical application favored SHH-related mechanisms.

This study found that while ethinyl oestradiol and cyproterone acetate effectively treated hirsutism in 90% of patients, 80% experienced relapse within six months after stopping treatment, suggesting long-term use is necessary.

This study suggests that the PI3K-AKT signaling pathway may significantly influence the development of different hair types in Inner Mongolia cashmere goats.
