Can this really be true? A cure for grey hair? L'Oreal has apparently discovered a way to 'switch on' the cells that switch off that turn our hair grey. No more colouring. Only a no-doubt pricey drug and your own natural hair colour back. I've had a patch of grey ever since I was about 17, but have noticed I'm going more and more grey now. The colour I can probably live with, but the "new" grey hair seems to be more wirey. Maybe the new drug makes the hair soft and luxuriant too?
