Redken's Acidic Bonding Concentrate Leave-in Treatment transforms hair, leaving it looking smoother and silkier. This deeply conditioning formula seals the cuticle and moisturises, minimising visible damage and promoting stronger, more resilient hair. Powered by Citric Acid and our Bonding Care Complex, this lightweight leave-in smooths the cuticle to reduce colour fade while boosting shine. Plus, it protects your hair from heat up to 230 degrees and tames flyaways for a polished, healthy look.
