How Exactly Does Bleaching Work?

Bleaching oxidizes melanin pigments in the hair and lightens its color. Bleach contains oxidizing agents like hydrogen peroxide and ammonia. These are chemically aggressive agents and can damage the hair shafts if you repeat the treatment (1).

While manufacturers claim their products are peroxide-free, it does not mean that they are free of harsh chemicals. It only means that the bleaching formula has some other bleaching agent, which will probably be just as harsh, if not worse.
