Essentially, graying hair is just natural, whether you have a full head of silver or patches of gray throughout. “Loss of pigmentation in hair is something out of our control,” agrees celebrity colorist and Redken brand ambassador Matt Rez. It’s largely due to genetics and aging in general, and unfortunately there aren’t any existing treatments to reverse those grays to their natural vigor.
Specifically, your pigment-producing cells (called melanocytes) start to deteriorate, leading to sprouted grays. “The melanocytes are pigment producing cells located near the bulb of the hair and their stem cells,” explains hair transplant surgeon James S. Calder, M.D., medical director of Ziering Medical. When your hair ages, those melanocytes don’t function as well or start to migrate away from the hair bulb, which causes a sprinkling of grays. And according to Calder, no supplement, nor diet, can successfully prevent the process forever.
