Hair thinning and shedding can feel isolating, but for millions of women in the UK, it’s a common challenge. Female pattern hair loss affects an estimated 8 million women nationwide. While prescription treatments like minoxidil and finasteride are effective, not everyone is comfortable using them, leaving many to explore alternative solutions.
A recent scientific review published in the Journal of Holistic Integrative Pharmacy highlights a potential new option: Polygonum multiflorum, a medicinal herb long used in traditional Chinese medicine. Researchers suggest the herb may support hair growth and reduce follicle loss in cases of androgenic alopecia, which affects both men and women.
How the Herb Works
Polygonum multiflorum, often called “He Shou Wu,” has been traditionally used to darken hair and enhance its fullness. According to Dr. Cindy Wassef, a dermatologist at Premier Health Associates in Randolph, New Jersey, laboratory and clinical studies indicate the herb may help “nourish hair” by protecting follicle cells from dying and stimulating regrowth.
One mechanism involves the inhibition of dihydrotestosterone (DHT), a hormone that contributes to follicle shrinkage. The herb may also support better blood flow to the scalp, helping deliver nutrients to follicles. Dr. Cynthia Bailey, a dermatologist and diplomate of the American Board of Dermatology, notes that studies suggest Polygonum multiflorum could elongate the hair growth cycle and potentially slow follicle aging, though its role in preventing greying remains uncertain.
Forms and Safety Considerations
Polygonum multiflorum is available in several forms, including crushed roots applied topically, teas, tonics, and even in certain skincare products. Dermatologists caution, however, that oral consumption carries serious toxicity risks. Topical applications appear safer, but results may vary depending on concentration and product quality.
Expert Advice for Those Experiencing Hair Loss
While the findings are promising, dermatologists stress that more research is needed. “It is not known how much is needed to see benefits for androgenic alopecia or how much is safe to ingest,” Dr. Wassef warns. She also emphasizes that the herb is unregulated, meaning teas, tonics, and supplements can differ widely in strength.
Until more studies confirm its efficacy and safety, dermatologists recommend sticking to well-established treatments for hair thinning and loss. For those hesitant to use conventional medications, Polygonum multiflorum may offer a potential alternative—but only with careful guidance and ongoing research.
