POLYGONUM MULTIFLORUM ROOT EXTRACT

Description

Polygonum multiflorum root extract, derived from the Chinese knotweed plant, is a potent ingredient in haircare formulations. This extract has gained attention for its traditional use in Chinese medicine to promote hair growth and prevent premature graying. Rich in antioxidants, particularly stilbene glycosides and 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside (TSG), it offers protection against oxidative stress that can damage hair follicles.

The extract is known to stimulate the proliferation of dermal papilla cells, which play a crucial role in hair growth cycles. It may also inhibit 5-alpha reductase, an enzyme linked to androgenetic alopecia. Studies suggest that Polygonum multiflorum root extract can increase melanin production in hair follicles, potentially reversing or slowing the graying process.

In haircare products, this ingredient is often incorporated into serums, shampoos, and conditioners targeting hair loss, thinning, and graying concerns. Its benefits extend to improving overall scalp health by promoting circulation and reducing inflammation. While generally well-tolerated, it's important to note that some individuals may experience scalp sensitivity. As with any potent botanical extract, patch testing is recommended before widespread use.
