Because if too many bonds are broken – hair becomes limp, if the sufficient number isn’t broken then the hair doesn’t straighten out.
The following chemicals are used: Sodium hydroxide, Ammoniumthioglycolate, Guanidine hydroxide, Ammonium (diammonium) sulfide, Cysteamine hydrochloride triethanolamine.
