Fo-Ti, aka He Shou Wu, is a revered plant in Traditional Chinese Medicine (TCM). It gained popularity in the West for its diverse herbal prowess. Fo Ti extract can not only improve hair growth, but also reduces stress hair loss.A 2015 study suggests that Fo-Ti stimulates hair growth by working on the FGF-7 gene, which encodes proteins specific to epithelial cell growth (and therefore hair growth) when administered orally. It also stimulates SHH expression. Studies suggest that the SHH gene, a crucial growth regulator in embryonic hair follicles, may also have an effect on postnatal hair growth when administered topically. Lastly, perhaps a more impressive Fo-Ti benefit for hair is its ability to significantly boost color. Research shows that Fo-Ti provides an effective grey hair solution – it is used to better maintain your natural color and delay the onset of new grays.
