There are three steps: Build, Enhance, and Recharge. In Phase 1, you add the Bond Builder to the color or lifting formula. It’ll repair broken bonds and create new ones while protecting the hair. In Phase 2, apply the Bond Enhancer, a deeply nourishing, restorative treatment that’ll strengthen the newly-created bonds, sealing strands to ensure long-lasting conditioning. Finally, Phase 3, the Bond Recharger, is the perfect home maintenance product that prolongs the effect of your Bond Fusion treatment.
