Use 1 to 3 times a week.Why use a pre-shampoo treatment?As well as the high concentration of actives found in this type of formula, using a filler on wet hair before your shampoo allows the ingredients to penetrate deep-down. Wetting hair before using the treatment ensures that the cuticles open up, helping the actives penetrate the hair; leaving the treatment on for at least 10 minutes gives the ingredients time to work properly.The application time and frequency of use also depend on how much damage the hair has suffered.
