No hair treatment can be permanent unless it penetrates the hair follicle. You do not put the TR solution directly on the scalp, it is protected. The stylist does this for 2 reasons: to prevent scalp irritation and also to prevent hair breakage from the bends. Some women prefer not to do any chemicals even hair color while they are pregnant. That is something between the new mother and her doctor. Ammonium thioglycolate is the main ingredient in TR which has been used in perms for years.
