Frequently Asked Questions

Q: How does the He Shou Wu (Polygonum multiflorum) shampoo bar help with gray hair?

A: Polygonum multiflorum, also known as He Shou Wu, is a traditional herbal ingredient believed to support melanin production in the hair follicle. Regular use of this hair darkening shampoo bar may help gradually restore natural dark pigment to gray or white hair, while nourishing and strengthening each strand from root to tip.

Q: How long does it take to see results from this hair blackening shampoo bar?

A: Results vary by individual. Many users begin to notice improvement in hair texture, shine, and reduced shedding within 2–4 weeks of consistent daily use. Visible darkening of gray or white hair may take longer, typically several weeks to a few months, depending on your hair type and the extent of gray coverage.

Q: Is this shampoo bar suitable for women or only for men?

A: While the product is listed for men, the formula is gentle and works for all hair types regardless of gender. It is suitable for anyone looking to darken gray hair, strengthen hair roots, or improve overall hair health. It can also be used on beards.

Q: Is the East Moon Hair Darkening Shampoo Bar safe for color-treated hair?

A: This shampoo bar uses natural plant-based ingredients and contains no high-concern chemicals. However, if you have chemically treated or color-treated hair, we recommend performing a patch test first and consulting your stylist to ensure compatibility with your current hair treatment.
