how long before i can get another perm
Generally about 3 to 5 months. After 3 months re-perm your roots so they match the rest of your hair. You can prep your hair. To prepare your hair for a perm, you'll want to use a protein conditioning treatment as well as a regular moisturizing conditioner after you shampoo. But don't deep condition your hair for at least 24 hours before the perm, otherwise the perm may not take.
