research Platycladus orientalis Leaf Extract Promotes Hair Growth via Non-Receptor Tyrosine Kinase ACK1 Activation
In this experimental study, the researchers observed that Platycladus orientalis leaf extract promoted hair growth by enhancing dermal papilla cell proliferation and increasing growth factor expression, particularly through ACK1 activation and modulation of Wnt/β-catenin signaling pathways in cultured human cells and a 12-week topical application.
