April 2024 in “Biomedicine & pharmacotherapy” 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.
July 2024 in “Frontiers in Pharmacology” This study suggests that pilose antler extracts promote hair regrowth in androgenetic alopecia mice by activating the AKT and Wnt pathways, enhancing hair follicle stem cell proliferation.
August 2025 in “Current Issues in Molecular Biology” This study demonstrated that Periplaneta americana extract significantly promoted hair regeneration in depilated mice by enhancing superoxide dismutase activity, upregulating vascular endothelial growth factor, modulating the FOXO/PI3K/AKT pathway, and restoring skin microbiome balance, suggesting its potential as a novel therapeutic candidate for alopecia.
January 2025 in “Cosmetics” In this study, the researchers found that Astragalus sinicus extracts improved wound healing, reduced oxidative stress, and activated crucial signaling pathways in dermal papilla cells damaged by dihydrotestosterone, suggesting it may be a promising ingredient for hair loss treatment.
May 2026 in “Frontiers in Cell and Developmental Biology” In this study, researchers suggest that hair follicle miniaturization in conditions like androgenetic alopecia may result from impaired conversion of quiescent stem cells to progenitor cells, influenced by the follicular niche, its collagen network, and various mechanical constraints.
