Hair regrowth herb: Study says this ancient medicinal root could help reverse hair loss

A centuries-old Chinese medicinal root is gaining renewed scientific attention as a potential solution for common hair loss. Polygonum multiflorum, long used in traditional Chinese medicine to restore dark, healthy hair, appears to act on multiple fronts, blocking hair-shrinking hormones, protecting follicles from damage, activating natural regrowth signals, and improving blood flow to the scalp, according to a recent ScienceDaily report.

How Polygonum multiflorum Could Help Hair Loss

Androgenetic alopecia (AGA), the most common form of hair loss, affects millions worldwide. While medications like finasteride and minoxidil are widely prescribed, concerns about side effects and long-term use have prompted patients to seek gentler, holistic alternatives.

As per a ScienceDaily study, Polygonum multiflorum may offer a new approach. Unlike standard treatments that target a single biological pathway, this herb seems to work on multiple levels simultaneously:


Reducing the effects of dihydrotestosterone (DHT), a hormone linked to follicle shrinkage.

Protecting hair follicle cells from premature cell death.

Activating key growth signalling pathways such as Wnt and Shh.

Improving blood circulation in the scalp, enhancing nutrient and oxygen delivery to hair follicles.

Ancient Wisdom Meets Modern Science

Han Bixian, lead author of the review published in the Journal of Holistic Integrative Pharmacy, told ScienceDaily:

"Our analysis bridges ancient wisdom and modern science. Historical texts from the Tang Dynasty onward describe effects that align with today’s understanding of hair biology. Modern studies now confirm that this isn’t folklore; it’s pharmacology."

The research combined historical texts, clinical observations, and laboratory studies to demonstrate how the root may do more than simply slow hair loss, it may actively support hair regrowth.

Beyond Slowing Hair Loss

According to the ScienceDaily report, Polygonum multiflorum may stimulate hair regeneration by influencing multiple growth factors and signalling pathways in the hair cycle. This broad mechanism of action could make it more effective than conventional treatments that target only one biological factor.

The study highlights that, when properly processed, a key step in traditional preparation, the herb is generally safe and well-tolerated. This makes it an attractive option for those concerned about side effects such as sexual dysfunction or scalp irritation linked to standard medications.

Safety and Need for Further Research

While initial results are promising, the authors emphasise that more high-quality clinical trials are required to confirm the effectiveness of Polygonum multiflorum and establish optimal dosing.

As per ScienceDaily, this review demonstrates how careful scientific study of traditional remedies can reveal new treatment strategies for widespread conditions like androgenetic alopecia.
