After shampooing, towel-dry hair thoroughly. Use the included brush to distribute an appropriate amount evenly through the hair. Leave on for about 5 minutes, or about 10 minutes if color is difficult to deposit. Rinse thoroughly until the water runs clear, then dry hair thoroughly immediately after use. Color results vary depending on the original hair color and hair characteristics.
Do not rub into the scalp. If color remains on your hands, wash it off immediately with soap. Avoid use for approximately one week before and after a perm or hair coloring. Wet hair may transfer color to clothing, towels, hats, or bedding. Rinse the brush well with water after use and store it in a clean place.
