A cure for gray hair could be available in the future after scientists said they had discovered the secret as to why follicles become discoloured as we grow older. Scientists found people who are going gray build up hydrogen peroxide in the hair follicle, which causes hair to bleach itself from the inside out.
This could be reversed by an antioxidant cocktail that allows re-pigmentation of the hair. The discovery was actually made whilst investigating the skin disease vitiligo, the condition which Michael Jackson suffered from.
