Hair Bleach
Bleach removes the color from your hair by the process of oxidation. "Oxidation decolorizes the pigment in your hair shaft, which is why bleach will turn your hair almost white if it's left on for too long. Very bleached hair often gains a yellow tint, because keratin (the protein your hair is made of) is naturally a pale yellow," says Cuannane Phillip. Bleach is made of hydrogen peroxide and ammonia.
