The occurrence of gray hair, besides being a natural part of aging, can also result from premature graying due to various causes. These include genetic predisposition, stress, nutritional deficiencies (such as copper and iron), and physical abnormalities like pituitary gland dysfunction, tuberculosis, and anemia. These issues can affect the function of melanocytes, the cells that produce melanin pigment in the hair bulb, reducing the melanin that reaches the hair and causing it to appear gray or white.

WKPep®Melit is a peptide that helps maintain natural hair color and reduce gray hair through the following mechanism:

WKPep®Melit is a synthetic peptide designed to mimic the natural structure of the α-MSH peptide, which binds to MC1-R to stimulate the enzyme tyrosinase, initiating melanin production. WKPep®Melit enhances the transfer of melanin from melanocytes to keratinocytes (skin or hair cells).

In-Vivo Test
An efficacy test was conducted on male volunteers aged 50 and above with gray hair. They used a blackening hair nutrient solution containing 10% WKPep®Melit, applying it to the scalp and massaging for 3-5 minutes twice daily for 12 weeks. The results showed an increase in the amount of black hair in the new growth, as illustrated in the accompanying image.
