Save Your Hair From Being Damaged When You Bleach It! by Save Your Hair From Being Damaged When You Bleach It!Before you bleach your hair get organic unrefined coconut oil, warm some up and spread it through your hair. Leave it on for a minimum of 1 hour (but you can leave it on all night if you want) then apply bleach on top of the coconut oil and leave in for the regular amount of time. This will help lessen the damage done to your hair. You're welcome. :)
