The Redken Acidic Bonding Concentrate Liquid Hair Mask offers bond repair and ultra-repair for dry and over-processed hair. With up to 72 hours* of hair-softening hydration, the mask results in visibly stronger and shinier hair. Developed with 16% citric acid, the five-minute mask provides intense moisture to the lengths, working to plump the fibres and protect against split ends and breakage. A conditioning complex supports the formula by detangling and promoting more manageability, alongside leaving the hair feeling silky-soft post-use. Suitable for all hair types, including colour treated. *Based on consumer test results when using acidic bonding concentrate shampoo and 5-min liquid mask
