We suggest that you wash the hair at least once or twice every 2 weeks with warm or cold water. Please wash the hair immediately after swimming, spa, exercise, and etc. When dirt and sweat accumulate, hair tangles. Too much leave-in conditioners and other hair care products will create a build up on the hair and will cause it to tangle faster. If the hair feels dry or heavy with build up, wash it with good shampoo & conditioner.It would be advisable NOT TO TINT, COLOR, PERM OR DO ANY EXTRA CHEMICAL PROCESSES because it has already been treated. Please be extra careful with blonde and other light colored hair.
