THIO • THIO FREE Thioglycolic acid is the classic agent for breaking sulphur bonds and altering the structure of the hair to make it smoother. It is a corrosive and very aggressive acid, which damages the structure of the hair. Due to this we use cysteamine chloride, which respects the nature of the hair without damaging it.
AMMONIA • A highly sensitising buffer agent, it may give rise to skin itching on application.
