Place your index finger in the hook hole and hold the brush. 1) As a hairbrush, brush before shampooing. Brushing before shampooing removes tangles and improves shampoo effectiveness! Tangle-free, smooth hair requires less shampoo to lather. (Individual results may vary.) When combing wet or tangled hair: Hold a small section of hair and comb from the ends, gradually working your way to the roots. Gently comb in one direction. Do not comb in the opposite direction. Wet hair tangles easily, so comb gently. When combing dry hair: Comb from the roots to the ends. 2) As a shampoo brush: Wash your hair: Lather shampoo well before use. Hold the brush as shown in the instruction illustration and wash your entire head using small, quick, and swishing movements. When changing the brush position, move it slightly away from the scalp. Wash the forehead from the hairline toward the top of the head. Wash from the hairline through the temples and around the ears. Wash the back of your head, working from the nape to the top of your head. 3) Use the brush as a treatment brush to work the treatment into your hair. This will distribute the treatment throughout your hair, enhancing its effectiveness. Apply the treatment to your entire hair, quickly work it in with your fingers, and then brush your hair to distribute the treatment throughout your hair. *Start by combing the ends of your hair, and once you can easily brush the entire length, gradually work your way down to the roots. Do not forcefully comb out tangled hair.
