The key is to sandwich your hair with the towel to absorb water, without rubbing. STEP 2: Apply the hair mask. Take an appropriate amount of the hair mask in your hand, and carefully apply it from the middle of your hair to the ends, being careful not to get it on your scalp. Gently massage it into your hair so that it covers the entire hair, leave it for a few minutes, and then rinse it off.
