Some good home remedies for relaxing a perm include thorough and repeated shampooing and conditioning, various oil treatments and using waving lotion. Home remedies do not completely straighten permed hair, but they can help to loosen the curls.
Treat permed hair by applying canola oil to dirty hair for one hour, then rinsing and gently shampooing. After rinsing, condition for 2-3 minutes. Repeat the process over the course of a week until you achieve the desired effect. Alternatively, shampoo the hair and apply a moisturizing conditioner. While the conditioner is on, comb the hair straight for 5-10 minutes. Rinse the hair, and apply an oil treatment.
