This study observed that pilose antler extract promoted hair growth in mice with androgenetic alopecia by stimulating the hair follicle growth cycle via the SHH/GLI pathway activation and BMP/Smad pathway suppression.

This study found that 0.75% adenosine lotion significantly improved hair growth and thickness in Japanese women with female pattern hair loss compared to a placebo.

Inhibiting Bmp signaling disrupts hair growth and differentiation.

This study describes a 4-year-old boy who exhibits a rare, synchronized pattern of hair growth and shedding, unlike the typical asynchronous pattern seen in humans.

This review found that androgenetic alopecia may be linked to increased cardiovascular and metabolic risks, but the relationship is not yet fully understood, and specific guidelines for cardiovascular disease detection and prevention in these patients have not been established.

TP0427736 may help treat hair loss by blocking a specific protein and promoting hair growth.

This study found that minoxidil sulfate did not enhance hair follicle growth or cell proliferation in isolated human hair follicles at concentrations of 0.1, 1, and 10 μg/ml.

This study found that the humanin analogue HNG significantly promoted hair growth in vitro and in vivo by prolonging the anagen phase and inhibiting hair follicle cell apoptosis in mice.

This study found that knocking out STAT5 expression in specific mouse hair follicles after tamoxifen treatment initiated uniform hair growth, highlighting STAT5's role in regulating the hair growth cycle.

The study found that Anagen grow, a herbal serum, promotes hair growth elongation and may inhibit the alpha reductase enzyme, suggesting it as a safe, effective alternative to finasteride and beneficial alongside minoxidil for reducing scalp dryness.

The serum with these ingredients may help reduce hair loss and promote growth.

This study found that leptin from dermal white adipose tissue may regulate hair growth and cycle progression through its receptor on hair follicle epithelium in mice and humans.

This study found that Centipeda minima extract promotes hair growth by activating Wnt/β-catenin, ERK, and JNK signaling pathways in human hair follicle dermal papilla cells.

This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.

This study found that administering an adenovirus vector to increase Sonic hedgehog gene expression in mouse skin accelerated the transition of hair follicles into the growth phase, promoting hair growth.

This study found that anagen-phase hair follicles in mice are particularly sensitive to damage by ruby laser pulses, resulting in alopecia without scarring, suggesting enhanced laser hair removal strategies.

This study found that dermal papilla cells in human hair follicles exhibit stronger expression of VEGF mRNA and protein compared to other follicular cells, suggesting their key role in angiogenic processes related to hair growth.

This study found that continuous expression of epidermal growth factor in transgenic mice prevented hair follicles from entering the catagen phase, implicating EGF as a crucial regulator in hair cycle progression.

This study found that topical minoxidil modestly extended the anagen phase in mice by activating β-catenin activity in dermal papilla cells.

In this study, topical application of fibroblast growth factors was found to promote hair growth by inducing and prolonging the anagen phase in telogenic C57BL/6 mice, suggesting potential as hair growth-promoting agents.

In this study, topical application of Thuja orientalis extract promoted hair growth by inducing the anagen phase and increasing hair follicle size and number in telogenic mice.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

This study found that leptin acts as an inducer of the anagen phase in hair follicles, suggesting its role as a potential player in hair biology.

In this study, researchers found that SIRT7 activates quiescent hair follicle stem cells to promote hair growth in mice by triggering the telogen-to-anagen cycle transition, with potential implications for age-related hair loss.

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

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 review discusses methods for evaluating hair growth-promoting effects of candidate substances for androgenetic alopecia, focusing on cell assays, organ cultures, and animal models, and reports no new results.

This article discusses the presentation of chemotherapy-induced anagen effluvium as either diffuse or patterned hair loss and reports no new clinical findings.

This review covers the structure, development, cycle, and molecular regulation of hair follicles but does not report new results, aiming to offer insights for addressing hair follicle-related diseases.

This study found that inducing hair follicles into the anagen-onset stage in mice enhances the immune response to a topically applied DNA vaccine against anthrax.
