Polygonum multiflorum is one of the most effective herbs in treating hair loss caused by hormonal imbalance or follicle malnourishment. Its constituent substances have been proved to be extremely effective in diminishing excessive hair loss and even growing hair in parts of the scalp affected by alopecia. The way in which Polygonum multiflorum manages to do that is still under debate.
According to the Chinese practitioners, alopecia is caused by impure blood which is unable to nourish the hair follicle accordingly. So, in their opinion, alopecia is a disease of liver and kidneys and once these organs function correctly, alopecia will disappear. Polygonum multiflorum has positive benefits on both liver and kidneys, which accounts, in Chinese view, for its remarkable effects in diminishing hair loss and promoting hair growth.
Hair Growth by Blocking DHT
Scientists have a different view of the way in which Polygonum multiflorum manages to stop hair loss. Alopecia areata is caused mainly by the excessive production of DHT which damages the hair follicle, until the hair strand falls and the follicle enters the telogen phase or dies out. Polygonum multiflorum inhibits the gland producing DHT, thus limiting its action on the hair follicle. Furthermore, it improves blood flow, thus bringing more nourishing substances through the capillaries to the hair follicle. This leads to a strengthened hair shaft, more volume for hair and a natural shine. Scientific reports have shown that during herbal hair loss treatments with Polygonum multiflorum, the number of follicles which have passed from telogen to anagen phase has increased significantly. This is why people using it report more volume in their hair.
Polygonum multiflorum is available as pills as well as topical ointment, each of them having great effects in treating hair loss and stimulating hair growth. Regardless of which explanation is more accurate, one thing is for sure: Polygonum multiflorum is as effective as chemical products available on the market and it is organic, thus providing less side effects. However, because it influences the hormone balance, it is not recommended to pregnant women.
