This study found that dermal papilla-like tissues derived from canine adipose stem cells promoted new hair follicle formation and increased vascularization in athymic nude mice.

This study found that Avicennia marina extract and its active compound avicequinone C inhibit enzymes and receptors related to androgenic alopecia, potentially supporting hair growth in cultured dermal papilla cells.

In this study, LED irradiation was found to promote hORSC proliferation and stimulate the Wnt5a/β-catenin and ERK signaling pathways, suggesting a potential mechanism for hair growth.

The study reported that lavender oil increased enzyme activity and cytokine expression linked to hair growth in C57BL/6 mice.

This study found that several small molecule peptides based on thymosin β4 significantly promoted cell proliferation related to wound healing, angiogenesis, and hair growth more effectively than established positive controls.

This study found that rat hair follicle stem cells can be effectively transfected with VEGF 165 using lentivirus vectors, suggesting their potential use in developing tissue-engineered skin with improved vascularization.

This study observed that using transfected human cord blood cells enhanced skin wound healing in rats by promoting angiogenesis and earlier termination of proliferation compared to untransfected cells.

This study found that ethanol extract and an ethyl acetate fraction of Sargassum fusiforme promoted hair regrowth in C57BL/6 mice and stimulated expression of hair growth-related genes in both in vitro and in vivo models.

This study found that Samhwang-Sasimtang herbal extract may enhance hair growth in mice, as indicated by increased hair follicle activity and reduced growth inhibition factors compared to a control.

This study found that Lycopersicon esculentum extracts applied to mice promoted hair growth similarly to minoxidil and increased growth factor expression, suggesting potential in hair loss treatments without skin irritation.

This study found that Chrysanthemum zawadskii extract may promote hair growth by inducing an earlier conversion of telogen to anagen and increasing the proliferation of dermal papilla cells in mice and human hair follicle cultures.

This study found that transplanting human cord blood mononuclear cells transfected with a plasmid encoding VEGF and FGF2 into rat skin wounds may accelerate the wound healing process.

This study found that oral administration of a ginkgo mixture increased hair growth and vascular endothelial growth factor content in C57BL/6 mice, suggesting a potential mechanism for hair growth promotion.

This study found that the methanolic heartwood extract of Avicennia marina significantly inhibited the enzyme 5 alpha-reductase type 1 in a cell-based assay, suggesting potential anti-androgenic effects for treating androgenic alopecia.

This study found that using a 0.5mm roller for microneedle therapy increased hair growth in mice and significantly affected the expression of hair growth-related molecules like VEGF.
