Question: 1 / 410

What effect does ammonia have in hair coloring?

Darkens hair instantly

Opens the hair cuticle for color penetration

Ammonia plays a crucial role in the hair coloring process, primarily by opening the hair cuticle, which allows color molecules to penetrate the hair shaft effectively. The cuticle is the outermost layer of the hair that protects the inner layers; in order for hair dye to work, it is essential that these molecules can access the inner structure of the hair. By raising the pH and swelling the cuticle, ammonia facilitates better absorption of the color.

The process involves the alkaline nature of ammonia, which disrupts the hair’s cuticle layer, thus preparing it for color application. This penetration is necessary for achieving the desired color effect, whether it’s lightening or depositing color. Therefore, the ability of ammonia to open the hair cuticle is fundamental to the effectiveness of hair dye and significantly influences the outcome of the coloring process.
