Restore and strengthen processed, damaged curls and coils with the Redken Acidic Bonding Curls Duo. This set contains a silicone-free Shampoo 300ml and Conditioner 300ml formulated with Curl Bond Technology to rebuild bonds from the inside out. Key actives — Citric Acid, Glycine and Urea — penetrate the hair cortex to rebalance hair to its healthiest pH (pH 4.5-5.5), seal the cuticle and improve curl elasticity. Avocado and coconut oils provide lightweight hydration and lasting softness without crunch or stiffness. The conditioner delivers intense conditioning for up to 96 hours based on consumer test results, while the shampoo gently cleanses and enhances natural curl movement. How to use: Apply the shampoo to wet hair, massage into a lather and rinse. Follow with the conditioner, applying from mid-lengths to ends and rinse. For best results use as part of the complete Acidic Bonding Curls regimen, including the Leave-In Treatment. In case of contact with eyes, rinse immediately.
