Fo-Ti (polygonum multiflorum), also known as Chinese climbing knotweed or “he shou wu,” is a popular, nutrient-rich herbal remedy common in traditional Chinese medicine. It has been used in creams, supplements, and ointments for various skin ailments and medical conditions for centuries.
How does Fo-Ti promote overall hair health?
Fo-Ti is regarded in Chinese medicine as the holy grail of hair health due to its powerful anti-aging and longevity properties. While Fo-Ti can reap numerous benefits on the body, the most popular is its effect on hair health. How does Fo-Ti help reduce hair graying?
Fo-Ti neutralizes the effect of hydrogen peroxide.
Small amounts of hydrogen peroxide molecules are naturally formed in our cells. With time this molecule is believed to damage the hair melanocytes, reduce the production of melanin and thus cause premature graying of the hair. In one study, it was found that taking Fo-Ti prevented hair bleaching effects of hydrogen peroxide and thus prevented and reversed hair graying.
Fo-Ti increases blood circulation and melanin production.
By nourishing the liver and kidneys, Fo-Ti has the ability to stimulate proper blood circulation throughout the body, including the scalp, which improves hair growth rate and nourishment by increasing the production of melanin which feeds and supports the hair follicles. The increased melanin production also boosts color in the hair, which helps maintain your natural hue and delay new gray hairs from developing.
Fo-Ti stimulates the hair growth cycle.
Studies have shown that Fo-Ti has the ability to help speed up the transition of hair follicles from the dormant stage of hair growth (telogen phase) to the growth stage (anagen phase) by working on the FGF0-7 gene, which encodes proteins particular to epithelial cell growth. This is especially important to those who are suffering from hair thinning or hair loss.
How to use Fo-Ti for hair health?
There are two common ways to use this herb, orally and topically.
- Oral consumption of Fo-Ti. Like many herbs, Fo-Ti can be taken orally in its raw form as a powder, extract, or capsule. While it is traditionally consumed as tea, it can be eaten as a soup or taken as a supplement. A typical dose is 2 - 3 grams, two to three times daily. Since this can have a mild sedative effect on some individuals, taking it in the evening before bed is recommended.
- Topical application of Fo-Ti. Fo-Ti can be found as an extract, sometimes called Polygonum extract, that can be applied directly to the skin or hair when diluted with a carrier oil.
