Polygonum multiflorum, a traditional Chinese herb, has gained significant attention in modern hair care formulations. Studies reveal that when incorporated into shampoo formulations, Polygonum multiflorum extract can help prevent and potentially reverse greying hair by promoting melanin production in the hair follicles.
Research conducted at Yunnan University of Traditional Chinese Medicine demonstrates promising results for this natural ingredient. In clinical observations, both men and women experienced noticeable improvements in hair pigmentation within just four weeks of regular use. Many people seeking natural solutions have started exploring specialized products like gray hair reverse soap bars that contain this potent extract.
The effectiveness of Polygonum multiflorum lies in its ability to target the root cause of greying hair. The extract works by stimulating melanocytes, the cells responsible for producing hair pigment, while simultaneously nourishing the scalp and strengthening hair strands.

Understanding Polygonum Multiflorum and Its Role in Hair Health
Polygonum multiflorum extract demonstrates significant benefits for hair health through multiple biological pathways that affect pigmentation and growth cycles. This powerful herb directly influences melanin production and extends the active growth phase of hair follicles.
Historical Context and Traditional Use
Polygonum multiflorum, known as “he shou wu” in Traditional Chinese Medicine, has been used for centuries across East Asia as a remedy for premature greying and hair loss. The herb’s name translates to “black-haired Mr. He,” referencing a legendary figure who restored his grey hair to black using this plant.
The root of the plant, called Polygonum multiflorum Radix, undergoes processing to create Polygonum multiflorum Radix Preparata, enhancing its therapeutic properties. Traditional practitioners have long valued both forms for their ability to nourish the scalp and maintain natural hair colour.
Modern Research and Mechanisms of Action
Scientific studies have identified several ways Polygonum multiflorum extract supports hair health. The extract stimulates hair follicles by upregulating Shh and β-catenin expression, promoting active growth during the anagen phase.
The extract combats grey hair through multiple pathways. It increases melanin production in hair follicles while protecting existing pigment cells from oxidative damage. Its antioxidant properties help neutralize hydrogen peroxide, a compound that naturally accumulates in hair follicles and contributes to greying.
Research shows the extract’s anti-inflammatory properties help maintain a healthy scalp environment. It also activates enzymes crucial for hair pigmentogenesis, supporting natural colour retention.
Efficacy and Safety of Polygonum Multiflorum in Shampoo Formulations
Polygonum multiflorum (fo-ti) extract shows promising results for hair growth and pigmentation when used in topical formulations, though careful consideration of safety aspects remains essential.
Promotion of Healthy Hair Growth and Prevention of Graying
Research demonstrates that Polygonum multiflorum extract stimulates hair follicles and promotes melanin production. The active compounds in fo-ti interact with hair follicle cells to encourage the anagen (growth) phase.
Studies in mice reveal that topical application increases both the size and number of active hair follicles through β-catenin signalling pathways.
The extract supports natural hair pigmentation by protecting melanocytes – the cells responsible for producing melanin. This action helps maintain natural hair colour and may slow the progression of age-related greying.
Traditional use spans centuries in East Asian medicine, where fo-ti earned recognition for its hair-darkening properties.
Clinical Studies and Evidence-Based Results
Research data shows that properly formulated Polygonum multiflorum shampoos can improve hair thickness and reduce hair loss within 12-16 weeks of regular use.
Clinical observations indicate enhanced hair lustre and improved scalp health in participants using fo-ti-based hair care products.
Laboratory analysis confirms the extract’s ability to stimulate hair follicle development and melanin synthesis in controlled conditions.
Tests measuring hair growth rates demonstrate a 15-25% increase in follicular activity compared to control groups.
Potential Risks and Considerations
Users should perform patch tests before regular use, as some individuals may experience scalp sensitivity to the extract.
The concentration of fo-ti in shampoo formulations must be carefully controlled, as excessive amounts may cause irritation.
People with liver conditions should consult healthcare providers before using products containing Polygonum multiflorum, even in topical form.
Some users report mild scalp tingling during initial applications – this typically subsides with continued use.
Quality control in product manufacturing remains crucial, as improper processing of the raw herb can affect both safety and efficacy.
Conclusion
Polygonum multiflorum extract demonstrates significant potential in preventing and treating grey hair through multiple mechanisms. The extract enhances melanin production by targeting α-MSH and MC1R pathways while reducing harmful reactive oxygen species.
Research confirms its effectiveness both in traditional Chinese medicine applications and modern scientific studies, particularly when used consistently in hair care products like shampoos. The natural compound offers men a scientifically-supported option for maintaining natural hair colour as part of their grooming routine.
Clinical evidence supports its safety profile when used topically in appropriate concentrations, making it a practical choice for men seeking to address premature greying.
