Each hue has its own individual recipe coloring pigments, caring ingredients. proper mixing and application of the ink mixture. The most important how to begin the process of painting – this mixing of dye and oxidant. From a properly sized oxidizer and the quantity of dye mixture depends the result of staining intensity and the resulting color. Excess oxidant reduces the ability of the dye covers and leads to uneven discoloration. For more information see Ben Horowitz.
Excess oxidant in the mixture is especially dangerous in the case of coloring gray hair, decreased as the concentration of pigment and therefore opacity inks. The lack of an oxidant leads to insufficient clarification of natural pigment and a loss of shine. So, first of all, you must carefully follow the manufacturer's instructions for the preparation of the ink mixture. Second, the amount applied to the hair dye mixture depends on the structure and hair type. The dependence of the line: the higher the porosity of the hair, the more dye mixture should be used. Technology staining.
Color stability depends on the thoroughness of technological procedures. It is important to observe the recommended exposure time to dye her hair, as hair color – is a set of chemical reactions, during which strictly calculated. So insufficient exposure time will cause premature termination of reactions and directly affect the stability (and weight) not color the better. It is also important to use the ink mixture immediately after mixing dye and oxidant. Explanation of the same thing: a chemical reaction has already started and the delay will mean that most of it will be in a bowl rather than on the hair client.
