Clairol recommends waiting seven to 10 days to color hair after having it permed. Since all chemical processes damage hair, someone wanting to color hair should also determine whether her hair is strong enough to withstand the color service.
Do not color hair if it is extremely dry or tends to break. Never apply color before getting a perm, as the chemicals often strip or pull color from the hair shaft, resulting in dull, faded hair. Always plan to color hair after getting a perm in order to revive the color and correct any color changes that occur as a result of the perm.
