When you are ready to rinse out the oil, hop in the shower and apply a dime-size or quarter-size amount of shampoo from your roots to your ends. The shampoo helps remove excess oil from your hair. Rinse out the shampoo, and apply conditioner as normal. Then, rinse all of the product out of your hair thoroughly.  To moisturize your hair even more, you can leave the conditioner on for 3 to 5 minutes while in the shower. For fine hair, you may want to skip conditioning after shampooing out the mask
