Step 2: Apply the hair color For the first color process apply the color mixture to unwashed hair strand by strand using a color brush. Make sure not to leave any strands. Then comb your hair with a wide-toothed comb to achieve an even distribution of the color mixture throughout your hair. For root coloring make sections in your hair and apply the dye mixture to the roots. Leave it on the hair to penetrate for 20 minutes then comb the dye evenly to the ends of your hair. Step 3: Soaking Time The time required for the hair to soak with the dye is 30 minutes. 20 minutes for root coloring and another 10 minutes for all of your hair.
