Redken Acidic Bonding Concentrate Leave-In Treatment Lotion is a lightweight, pH-balanced leave-in treatment designed to strengthen and protect fragile, damaged hair. Enriched with the Acidic Bonding Complex, it rebuilds broken bonds, smooths the hair cuticle, and enhances elasticity—all without weighing hair down.

Ideal for chemically treated, brittle, or weakened hair, this leave-in lotion provides heat protection and improves manageability while reducing breakage. It leaves hair feeling stronger, smoother, and visibly healthier.

Apply to damp hair before styling. Do not rinse out. Style as usual for enhanced bond repair and protection.
