Hair Growth Effect of Sasa Veitchii Extract in Mice

The study investigated the hair growth effects of kumazasa extract using human hair follicle dermal papilla cells (HFDPC) and a mouse model. Kumazasa extract was found to promote cell proliferation and increase AQP1 expression, similar to epidermal growth factor (EGF). In mice, kumazasa extract demonstrated a hair growth effect comparable to minoxidil but without causing inflammation, unlike minoxidil. The study suggests that the hair growth effect may be linked to the proliferation-promoting properties of kumazasa extract on HFDPC, although the relationship with AQP1 expression remains unclear.
