You’ve gotten the perm, now you need to know how to take care of it. *Use a diffuser to blow-dry the hair, leaving the curl undisturbed. *Use warm water. Hot water tends to release whatever effect the perm has on the hair. *Don't use brushes, only wide-tooth combs. *If you want to comb permed hair, the time to do it is when you have conditioner in your hair. *Permed hair is fragile and prone to breakage. Don't use rubber bands to tie the hair back.
