Chinese Fleeceflower, also known as Polygonum multiflorum or He Shou Wu, is a traditional Chinese medicinal herb that has been used for centuries to support hair health and combat hair loss. In Traditional Chinese Medicine (TCM), it is believed to nourish the liver and kidney, organs that are thought to play a key role in hair growth and pigmentation according to TCM theory. The use of He Shou Wu for promoting hair growth and preventing premature graying is well-documented in classical Chinese medical texts and remains popular in East Asian herbal practices today.

Despite its longstanding use in tradition, scientific evidence supporting the effectiveness of Chinese Fleeceflower for hair health is limited and largely preliminary. In vitro and animal studies have suggested potential mechanisms, such as promoting hair follicle cell proliferation and increasing melanin production, but robust clinical trials in humans are lacking. Some small studies and anecdotal reports hint at possible benefits, but these are not sufficient to establish efficacy by modern scientific standards. Moreover, there are concerns regarding liver toxicity with prolonged or high-dose use of He Shou Wu.

In summary, the use of Chinese Fleeceflower to support the hair body system is primarily justified by traditional use rather than strong scientific validation. Individuals considering its use should do so with caution and consult healthcare providers due to potential safety concerns.
