Did you mean Hair Repigmentation?

Glossary Hair Repigmentation

process where gray or white hair regains its original color

Hair repigmentation refers to the process by which hair that has turned gray or white regains its original color. This can occur naturally due to changes in the body's biochemistry or through medical treatments that stimulate melanin production in hair follicles. For professionals, it involves understanding the underlying mechanisms of melanin synthesis and the factors that can influence this process, such as genetics, hormonal changes, and certain medications or therapies.
