Wash your hair with a gentle moisturizing shampoo made for chemically treated hair on day three. These shampoos will have natural, soothing ingredients for those stressed tresses after a perm. Use gentle massaging motions on the hair and rinse thoroughly. Only use warm water when washing your perm, never hot.
If one only seeks to maintain a particular hairstyle, the recommended time between perming treatments is six to eight weeks. Even for hairstyle maintenance, it is generally advised that the hair should be cared for with deep moisturizing treatments for several weeks before the perm treatment. Immediately before each perm treatment, it is advisable to take a hair strand test to see if the hair is ready for another perm.
