This study found that topical application of 17 alpha-propylmesterolone significantly increased proliferative activity in hair matrix cells in men with androgenetic alopecia.

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 observed unexpected heterogeneity among pigment cells in human scalp hair follicles, identifying immature melanocyte populations outside traditional pigment production zones, raising questions about their potential roles beyond melanin synthesis.

In this study, researchers explored the heterogeneity of pigment cells in the human scalp anagen hair follicle bulb and discovered unexpected subpopulations of melanocytes, including immature SOX10-negative cells, highlighting potential non-melanogenic roles or transitional migratory functions that require further investigation.

The researchers reported that the OVOL1-OVOL2 axis may play a role in hair follicle differentiation and tumorigenesis, and OVOL1 and OVOL2 are potential diagnostic markers for pilomatricoma and pilomatrix carcinoma.

This study found that ATM protein plays a crucial role in protecting human hair follicle melanocytes from oxidative stress, which is linked to the greying of hair.

This study found that a combination of spermidin, rutine, and zeaxantine effectively reduced staurosporin-induced apoptosis in cultured hair follicle dermal papilla cells, potentially preventing the regression phase in the hair follicle cycle.

This study found that several anti-cancer agents strongly inhibit DNA synthesis in human hair germinative cells, while certain cytokines showed only slight inhibition.

This article reviews the biological and physical principles of laser hair removal and reports that current laser systems do not consistently achieve permanent hair follicle destruction across treated areas.

Lack of protein causes hair root damage, but it can be reversed by eating protein again.

Hair follicles form hard α-keratin filaments in four steps, showing structural differences.

This study found that during dialysis, lower plasma-potassium levels were associated with hyperglycemia, suggesting potassium correction is vital when using glucose-rich dialysate.

This study found that epimorphin is closely linked to developing hair follicles in human fetuses, suggesting it plays a significant role in hair follicle morphogenesis.

This study found distinct localization patterns of S100 family proteins in hair follicles, suggesting their differential roles in normal hair follicle physiology.

This study found that the alcohol extract of Vernonia anthelmintica may counteract stress-induced hair follicle growth inhibition in mice, potentially offering a new approach for treating stress-related hair loss.

In this study, azelaic acid was found to enhance UVB protection in bulge cells and, when combined with minoxidil, may promote hair growth through increased Sonic hedgehog protein expression in hair follicles.

In this study, certain Chinese herbal medicines were found to significantly stimulate or inhibit hair growth in an in vitro organ culture model of mouse vibrissa follicles.

Ashwagandha nanoparticles help hair grow by increasing a growth factor.

This study explores the potential of rosemary oil for stimulating hair growth, focusing on developing ROS-loaded microsponges to enhance its permeability for topical application, but results are not reported.

This study investigated the hair growth-promoting effect of topical nebivolol cream in mice, but the abstract does not provide specific results or conclusions.

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

This study found that rat whisker follicle stem cells can be expanded in culture and transplanted to form functional hair follicles, demonstrating their multipotency and potential for regenerative medicine.

This review discusses the development, regulation, and aging of the human hair follicle pigmentary system and suggests potential for reversing hair graying by manipulating follicle melanocytes in vitro, but reports no clinical results.

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

This study suggests that melatonin plays a role in hair follicle function by modulating growth and pigmentation, and it may act as a protective agent in active hair growth phases.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

This review discusses the role of immune privilege collapse in the pathogenesis of alopecia areata, emphasizing the potential for therapeutic manipulation of hair bulb immune privilege to offer new treatment options, and reports no new results.

This study found that prolactin and its receptor are expressed in the murine hair follicle epithelium, influencing hair cycle phases by down-regulating keratinocyte proliferation during anagen and inducing premature catagen.
