    Glossary Hair Bleaching

    chemical process lightening hair by breaking down melanin pigment

    Hair bleaching is a chemical process that lightens the natural color of hair by breaking down the melanin pigment within the hair shaft. This is typically achieved using a mixture of hydrogen peroxide and ammonia, which opens the hair cuticle and allows the bleaching agents to penetrate and dissolve the color molecules. The result is lighter hair, which can range from a subtle lift in color to a platinum blonde, depending on the duration and strength of the bleaching process.
