Do you know what the different types of volumes in cosmetic hydrogen peroxide are for?
The hydrogen peroxide, or Ox, is an important ally when it comes to discoloring, coloring or making locks, as it is she who will open the hair cuticles and expose the part where the hair color pigment is, so that the bleaching powder or colorings act on them. It causes hair to become oxidized, and in contact with ammonia it generates a chemical reaction that releases oxygen, allowing the bleaching powder to enter and remove pigmentation from the hair.

The main powers of cosmetic hydrogen peroxide are 10, 20, 30 and 40 volumes, and each of these volumes serves a different application. But first you need to identify the base color of your hair to be able to know how many shades you want to be opened after its original tone. For example, if your hair tone is 4 (Medium Brown), you count from 4 onwards how many shades the chosen Ox can open together with the bleaching powder.
