Step 1: After shampooing, while hair is still damp. Lift hair to the top of your head and wrap the hair mask cap around your entire head. Step 2: Remove the film behind the sticker and adjust the hair mask to the width of your head. Stick the sticker at the front of the mask to secure the mask cap in place. Step 3: Lightly massage your hair from outside the cap to make sure the treatment covers every hair strand. Step 4: Leave mask on for 15-20 minutes and rinse with lukewarm water. Follow up with conditioner if needed.
