Grey hair may soon be a thing of the past. Scientists have found the cause of greying hair and a clue on how it can be reversed:
Scientists found people who are going grey build up hydrogen peroxide in the hair follicle, which causes hair to bleach itself from the inside out.
However this could be reversed by "an antioxidant" cocktail that allows "re-pigmentation" of the hair.
The discovery of what makes hair grey, published in the FASEB (Federation of American Societies for Experimental Biology) journal, was actually made whilst investigating the skin disease vitiligo. [...]
The team, which included experts from Bradford University's School of Life Sciences, blamed "massive epidermal oxidative stress" that leads to the build up of hydrogen peroxide.
