The whole thing works like this:in the basic colour-usually a more or less creamy emulsion-there are few primary constituents. These substances are made up of tiny particles. In the first phase, they penetrate the outer scaly layer of the hair. In the second phase, the oxidisation medium takes efect. It binds the primary substances of the colouring to the pigment they are then so enlarged that they can not leave the hair.
