To lighten the natural color of the hair

The primary purpose of hair bleach is to lighten the natural color of the hair. Hair bleach contains strong chemical agents, typically hydrogen peroxide or ammonia, which work to break down the natural pigments in the hair shafts. This process of oxidation effectively removes or alters the existing color, resulting in a lighter shade.
