A: Oxymelanin is the byproduct of the bleaching process that takes place when you perform hair color removal services of any type (even the naturally-occurring bleaching of the hair when in the sun). The hydrogen
peroxide of high-lift developers and lightening mixes is responsible for dispersing the color molecules of melanin. What actually occurs is that the hydrogen peroxide oxidizes the melanin of natural pigments (melanin)
and forms a colorless substance called “oxymelanin”.
The oxidation reaction is caused by the alkali in the hair bleach mixture reacting with the hydrogen peroxide. It causes the peroxide to release nascent oxygen which is what causes
the release of hair color, and leaves behind the pigment molecules in an altered form, which is where the “oxy-melanin” term comes from.
