More Information

Hair dyeing is a cosmetic method to change hair color, typically achieved by applying hair dye to transition from one color to another. The principle of hair dyeing involves chemical substances penetrating the hair's cuticle layer and reacting with its natural pigments to alter its color.

Hair dyeing relies on chemical reactions. Different types of hair dyes operate on distinct principles. For permanent hair dye, for instance, the dye and oxidizing agent (usually hydrogen peroxide) are initially mixed. This activates the dye precursors in the dye, allowing them to penetrate the hair fiber. These dye precursors infiltrate the hair's cuticle layer and reach the cortex. Within the cortex, they undergo an oxidation reaction with the oxidizing agent, forming large pigment molecules. These molecules combine with the hair's natural melanin, creating new pigment complexes that alter the hair color.

Types of hair dyes include:

Permanent hair dye

Semi-permanent hair dye

Temporary hair dye

Natural hair dye
