THE PRINCIPLE OF ACTION OF OXIDATION (Permanent) DYES

Oxidative hair dye works in accordance with the principle of an attachment of pigment in the hair structure. During the process of coloring hair there are many processes, play a role:

- Ammonia is the cause of opening the cuticle.

- Not formulated pigments penetrate the hair structure.

- Due to mixing paints (alkali) and the developer (hydrogen peroxide), oxygen will be separated. This resulted in the oxidative process, pigments will develop in large molecules.

- And if pigments evolved, they can't get out of hair rinse, due to their large size,. The number and composition of pigments determines the color level, coverage and color character.

- During the chemical process for colouring hair free oxygen turns the natural pigment of the hair in a colorless soluble substance, in place which made artificial pigments, forming new hair color.

- Since the oxidation rate of different components varies, to obtain the necessary nuance recommended exposure time must be followed, otherwise not all pigments have time to appear and work, that will adversely affect getting the desired color.

- Porous hair is causing poor encapsulation pigments, bringing coloring, particularly the Red pigmentation, will not last long.
