A botanical extract may help manage hair loss from chemotherapy by preventing cell death in hair follicles.

This study found that FGF18 is crucial for regulating hair follicle rest and growth phases, as its absence in mice leads to a shorter resting phase and rapid hair cycling.

This abstract discusses the potential of platelet-rich plasma as a promising solution for hair loss and thinning, highlighting its efficiency, safety, and reproducibility compared to traditional treatments like hair grafts.

This study sequenced and analyzed the goat skin transcriptome, revealing genes involved in signal transduction and cell communication that are differentially expressed during hair growth phases, providing insights for Cashmere goat breeding.

This study used single-cell RNA sequencing to analyze 26,573 cells from the scapular skin of yaks, identifying 11 major cell types and providing insights into the diversity and morphogenesis of hair follicle cell types through detailed maps of DP cells and dermal fibroblasts.

This article reviews the complex signaling pathways between epithelial and mesenchymal cells crucial for hair follicle morphogenesis, highlighting the Wnt pathway's role as a master regulator without reporting new experimental findings.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

Apoptosis in hair follicles varies by growth phase, with TGF-β possibly starting the catagen phase.

In this study, T3 and T4 were found to directly influence human hair follicles in vitro, enhancing keratinocyte proliferation, prolonging the hair growth phase, and affecting pigmentation.

This review discusses developments in oral contraceptives, highlighting improved individualization, reduced side effects, and enhanced suitability for various women's health needs, but it reports no new clinical results.

This review examines the role of retinoic acid synthesis in hair follicles and sebaceous glands, focusing on its localization and function during normal and disease states, but reports no new results.

This article discusses how drug molecules integrate into hair fibers, focusing on biological transport mechanisms and physicochemical factors, but reports no new experimental findings.

This study found that ionizing radiation primarily affects keratinocyte stem cells in the hair follicle, suggesting they play a central role in radiation-induced hair graying, rather than melanocyte stem cells.

This study found that combining ablative fractional CO₂ laser therapy with hair growth factors significantly increased hair density in men with androgenetic alopecia compared to using growth factors alone.

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 paper reviews recent research on hair graying, suggesting that an imbalance in oxidative stress handling may affect melanocyte stem cells and melanin production with age, and calls for exploring strategies to prolong melanin production.

This study identified distinct gene expression patterns in wool follicle bulbs that may play important roles in wool follicle cycling and regeneration in sheep.

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

This study found that in Pomeranians with Alopecia X, key genes in the Wnt and Shh signaling pathways and stem cell markers are downregulated, which may explain the absence of anagen hair follicles.

This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

This study found that overexpressing the gene Thymosin β4 (Tβ4) can promote the growth and development of secondary hair follicle dermal papilla cells in cashmere goats, suggesting its potential as a target for increasing cashmere production.

In this review, researchers summarize key factors in constructing skin organoids, including cell source and assembly methods, and emphasize advances such as air-liquid interface culture for improving tissue development, aiming to guide standardized protocols and future clinical applications.

This review suggests that the mTOR signaling pathway may play a significant role in hair follicle health by influencing the effects of Vitamin D receptor deficiency, potentially contributing to hair follicle damage and related hair loss conditions.

This study found that HtrA2 inactivation in mnd2 mice is associated with delayed hair cycle phases and growth retardation of adipocytes, suggesting HtrA2's role in regulating adipogenesis-related hair growth.

This review discusses the application of mesenchymal stem cells and their secretory factors for skin and hair regeneration and reports no clinical results; the authors highlight the progress and call for practical applications.

This study found that activating Wnt/beta-catenin signaling in hair follicles is sufficient to induce adipocyte generation in the dermis, affecting both hair follicle stem cell activation and adipocyte differentiation.

This article highlights studies on cholesterol transporter proteins in hair cycles, epithelial-to-mesenchymal transition in cancer, ovarian hormone effects on cell polarity before implantation, and UV effects on rodent skin, without providing new clinical results.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This review provides a comprehensive overview of melatonin's physiological roles, effects, and clinical implications, but it does not present new experimental findings.

This review discusses the critical role of BMP signaling in the development and regulation of skin and hair follicles and notes that further research could aid therapeutic advances; it presents no new clinical results.
