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.

This study found that m6A-circRNA-ZNF638 enhances the activation of secondary hair follicle stem cells in cashmere goats by interacting with the miR-361-5p/Wnt5a pathway.

The document explains the genetic causes and characteristics of inherited hair disorders.

This study found that inhibiting mTORC1 activity with rapamycin increased both hair growth and pigmentation in human scalp hair follicles, suggesting a potential strategy for treating greying and hair loss.

This study found that Manganese PCA, Cinchona succirubra, and Leontopodium alpinum extracts may promote hair growth by enhancing VEGF secretion and activating the Wnt/b-catenin pathway in Human Hair Follicle Dermal Papilla Cells.

This study found that two unrelated domestic shorthair cats had novel DSG4 gene mutations causing defective hair shafts, representing the first report of pathogenic DSG4 variants in domestic animals.

This study found that a shampoo containing a 6-active ingredient complex increased β-Catenin production in human hair follicle dermal papilla cells to levels comparable to Finasteride, suggesting potential for promoting hair growth. It also showed good cleaning efficacy, volume, and shine in a sensorial study.

This study found that the absence of Hif-p4h-2 in specific mouse skin cells disrupted hair follicle development, leading to hair loss due to irregular keratin formation and pathway signaling.

This research suggests that mouse mutants and genomics can help study hair biology and epithelial differentiation by focusing on the role of the Foxn1 gene.

This chapter reviews the presence and roles of stem cells in various body systems, focusing on their lifelong function in animals and humans, and reports no new experimental findings.

In this study, researchers identified 18 genetic associations with scalp and facial hair traits in Latin Americans, including novel loci for hair greying and balding, with implications for understanding hair evolution.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

This study found that transcriptome profiling of cashmere goat skin revealed key genes and pathways involved in hair follicle initiation, differentiation, and maturation, which are critical for improving fleece production.

This study found that overexpression of Smad7 in transgenic mice led to severe alterations in multiple epithelial tissues, resulting in early death after birth.

This review examines the differential aging of melanocytes in hair follicles and skin, and reports no new findings; the authors suggest further research is needed to understand these processes.

This study demonstrates that inhibiting SFRP1 with the antagonist WAY-316606 enhances hair growth in human scalp hair follicles ex vivo by facilitating Wnt signalling.

This review discusses the roles and mechanisms of Wnt signaling in embryonic and adult stem cells and its association with cancers, and reports no new experimental findings.

This study found that androgen receptor activation in adult mouse skin reduces β-catenin-induced hair follicle growth and sebaceous gland conversion, highlighting its role in stem cell fate decisions.

This review discusses how neuroendocrine pathways influence keratin regulation in human skin and hair follicles and suggests these pathways as potential targets for new treatments of skin disorders, but reports no clinical results.

This study reports that milk goats exhibit significantly more differentially expressed genes related to hair follicle cycling across different months compared to cashmere goats, especially in December.

This review discusses the early phases of melanomagenesis and the factors influencing melanoma cell variability and reports no new clinical results.

This study observed that mTORC1 signaling is activated and crucial for hair follicle regeneration and hair growth in irradiated mice, facilitating recovery within 96 hours without significant hair loss.

This study suggests that specific combinations of human type I and II hair keratins, particularly K35-K85 and K36-K81, have distinct in vitro assembly properties that are significant for macrofibril formation.

This review discusses the challenges in identifying specific hair follicle antigens involved in initiating alopecia areata and highlights the need for further research to understand its etiopathogenesis, reporting no new results.

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 article explores the potential of combining biomarkers to assess and improve treatments for chemotherapy-induced alopecia, highlighting the limited availability of data on hair follicle damage markers with and without scalp cooling.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.

In this study, XMU-MP-1 unexpectedly reduced cell proliferation and altered cell cycle progression in a model human hair follicle, possibly due to off-target kinase inhibition.

This review discusses the processes of melanocyte stem cell quiescence and activation, focusing on their interaction with hair follicle stem cells, and highlights current research on hair graying mechanisms; it reports no new results.

This study developed a new human in vitro hair model that replicates in vivo hair characteristics and may be suitable for high throughput screening of hair growth treatments.
