Effective on their own, but even more powerful when used together, the three hair heroes in this kit go as follows. First, there's the No.3 Hair Perfector, a once-a-week pre-wash treatment that seeks out broken bonds in the hair (which are caused by chemical, thermal and mechanical damage) and repairs them, restoring compromised hair to former glory in the process. Then, there's the No.4 Bond Maintenance Shampoo. A daily cleansing and repairing shampoo, this silky fluid gently cleanses away dirt, oil and product build up while hydrating and strengthening hairs as well as repairing shattered hair bonds. Next, there's the No.5 Bond Maintenance Conditioner, which repairs hair bonds and gently restores hydration levels without adding excess weight. They say 'three is a magic number' and we can see why: this transformative trio works frizz-free, repairing magic on weary manes.
