Question: how long do i have to wait to wash my hair after perm?
Answer: You should wait about 48 hours until you wash your hair after a perm. If you shower before then, the curls may come out uneven. Do I add conditioner in the shower or after? You add it in the shower but just make sure all the shampoo is rinsed out before you do so, otherwise you won't get the benefits of conditioning.
