People with grey hair could one day pop a pill if they want to restore their hair to its natural colour. Scientists at French cosmetics giant L’Oreal have identified a pair of genes that may play a key role in turning hair grey. They say these genes may determine how long many of the cells that give hair its natural colour live. They believe that by targeting these genes they may be able to help these cells live longer, preventing grey hair. Hair turns grey when the cells that give it its colour die. However, the French scientists have found that some of these cells, which are called melanocytes, survive even when somebody’s hair has turned grey.
