Decolorizing agents

The difference between bleaching and coloring the hair lies in the effect of the individual solutions on the hair structure. Experience has shown that the most suitable substances for hair bleaching are peroxides, especially hydrogen peroxide, with the simultaneous use of ammonia or ammonium salts. It is understandable that the process of hair bleaching is accompanied by physical and chemical changes in hair structure, as bleaching is quite a deep intervention in the structure of hair.

Just as you color the pigment grains in the hair cortex with a new color shade, so when you discolor, you dissolve the pigment grains with a bleaching solution. This is also the reason why once bleached hair absorbs a potential color solution so poorly. Where the pigment grains are dissolved, the paint molecules have no chance of being trapped.

• It is necessary to realize that changes are irreversible. Once bleached, the hair can no longer darken, as no pigment is newly formed in the bleached part of the hair. Only on growing hair can we observe the interface of the naturally colored and discolored part of the stem.
• Repeated or even frequent bleaching of already bleached hair deepens the adverse effect of the bath and leads to easily noticeable changes in hair quality (matte, brittle and dry hair).
• Bleach only the newly growing part of the hair and do not bleach the part of the hair that has already been bleached once.
