Important information cover gray hair-long regrowth

Gray hair - long regrowth:

Virgin hair needs a much longer working time than hair that has already been colored. Color on top of already colored hair will always be darker than where the hair is virgin. If the color is to be extracted in already colored hair, this should be done towards the very end of the working time or simply foamed up during rinsing. For better coverage, the working time can be extended to 45 minutes. Start application where you have the most gray hair.
