Wash your hair, clean the scalp well. put the masque on your hair and scalp if your scalp is also dry, saturate hair evenly and put on a shower cap. you can wear it for 20 minuets casually as long as it doesn't get cold. In the salon we put you under a dryer but you can use a hair dryer or use it in the shower and the heat in there should keep it warm. take the cap off and rinse out and your good to go :) Do this once a week if needed.
