Nearly 30 million women in the United States experience androgenic alopecia, commonly known as female pattern hair loss. While prescription treatments like finasteride and minoxidil exist, many seek alternative solutions. Now, a growing body of research suggests that Polygonum multiflorum, a herb deeply rooted in Traditional Chinese Medicine, may offer a natural approach to combating hair shedding and promoting regrowth.
The Science Behind the Herb
Polygonum multiflorum has long been used to darken hair and improve its fullness. Recent scientific reviews, including studies published in the Journal of Holistic Integrative Pharmacy, have begun to validate its potential. Dermatologists explain that the herb appears to work through multiple pathways, including blocking dihydrotestosterone (DHT) – a hormone linked to follicle shrinkage – and protecting hair follicle cells from premature death.
The herb may also stimulate regrowth signals and improve blood flow to the scalp, delivering more nutrients to follicles. Laboratory studies suggest that it can extend the hair growth cycle, potentially slowing or reversing hair loss and graying. However, experts caution that the exact mechanisms behind hair graying are still poorly understood, making definitive claims difficult.
How It’s Used and Potential Risks
Polygonum multiflorum is available in several forms: crushed root for topical application, oral supplements, and ingredients in some facial creams. Dermatologists warn that oral consumption carries significant toxicity concerns, while topical use appears less risky. However, the herb is unregulated, and the concentration of active compounds can vary widely between products.
Key takeaway : “It is not known how much is needed to see the benefits for androgenic alopecia and how much is safe to ingest,” says Cindy Wassef, MD, a dermatologist at Premier Health Associates.
Expert Caution and Alternatives
While the data on Polygonum multiflorum is intriguing, dermatologists stress the need for more rigorous research before widespread adoption. Currently, only topical minoxidil and oral finasteride are FDA-approved treatments for androgenic alopecia.
Before experimenting with alternative remedies, individuals experiencing hair loss should consult a dermatologist for a proper evaluation. Proven treatments offer more reliable results, and unregulated herbal supplements may pose unknown risks.
Relying on well-studied options, under professional guidance, remains the most effective and safest approach to combatting hair thinning and loss.
