How Does Bleach Affect Hair at the Cellular Level?

Bleach affects hair at the cellular level by altering its structure. Hair consists of a protein called keratin. When bleach, which contains hydrogen peroxide, is applied to hair, it penetrates the hair shaft. This penetration occurs through the cuticle, the outer protective layer of the hair. Once inside, the bleach oxidizes the melanin, which is the pigment that gives hair its color.

The chemical reaction breaks down the melanin molecules, lightening the hair’s color. Along with this, bleach can also damage the keratin structure. It can weaken the bonds that hold the protein together, leading to hair that is more porous and fragile. This structural damage can result in increased brittleness and a higher risk of breakage.

Subsequently, the hair may lose moisture and become dry. This degradation alters the overall texture and appearance of the hair. In conclusion, bleach changes hair color by breaking down melanin and compromises the hair’s strength and integrity at the cellular level.
