Dyes are created by arrangements of molecular structures. They modify light rays.
This is known as color saturation. Permanent hair color is a mixutre of lifting and depositing agents. The greater the proportion of depositing agents, the greater the color saturation. Lift and deposit CAN be modified (a bit) by changing the volume of hydrogen peroxide used in the formula.
Remember this: A level 8 hair color is 80 percent "lift" and 20 percent "deposit".
A level 4 hair color is 40 percent "lift" and 60 percent deposit" ...and so on. The
higher (lighter) the level of a color, the more it will lighten, and the less tone it
will deposit. Remember ALWAYS that the final result is the combination of both
the color formula AND the natural hair color level to which the formula is applied.
Never looked at hair color quite like this. Thanks for the insight.
