"When hair goes gray, there is a progressive disappearance of the melanocytes (pigment-producing cells) from the hair. While there are still melanocytes in the hair, there is still hope that it could be re-pigmented," L'Oréal's Patricia Pineau told the Daily Mail. Supposedly, the process would involve some type of oral component, along the use of specially formulated haircare products. What do you think of this treatment in the works? Is it just messing with Mother Nature, or do you welcome what science has to offer when it comes to antiaging developments?
