    Studysummary In this in vitro study, baicalin promoted human hair follicle growth, potentially by enhancing VEGF secretion by dermal papilla cells. Our plain-language summary of this paper — not a Tressless recommendation.
    The study investigated the effects of baicalin on human hair follicles and dermal papilla cells (DPCs) in vitro. Baicalin at concentrations of 7.5, 15, 30, and 45 μg/mL significantly promoted hair shaft elongation in cultured hair follicles. Although baicalin did not significantly affect the proliferation of DPCs at concentrations of 3.75, 7.5, 15, and 30 μg/mL, it significantly increased the secretion of vascular endothelial growth factor (VEGF) by DPCs. The findings suggested that baicalin could promote hair follicle growth, potentially through the stimulation of VEGF secretion by DPCs.
