Pour the base colour made from plant extracts into the shaker with the tip-applicator that contains the developer fluid. Shake the mixture and apply it to the full length of your hair starting from the roots and covering the entire length, lifting sections of hair so that air reaches all areas and you obtain excellent coverage of your hair, and then, with a large-toothed comb, comb your hair so as to distribute the colour well over your hair. Leave on for 30 minutes, rinse thoroughly and shampoo gently. After patting the hair with a wash cloth, apply the hair mask, leave on for a few minutes, rinse thoroughly and dry.
