Coconut, Argan, Shea and other oils are wonderful treatments for your hair as they restore and seal in moisture. Constant use of oils prior to treatment can permeate the hair and prevent Hairprint from working optimally.
Please stop applying oils to your hair at least 3-4 days before applying Hairprint (ideally a week). Please cleanse your hair with a clarifying shampoo before you wash with the Pretreatment. See our Hair Residue FAQ for shampoos that will work.
