Acidic Bonding Conditioner is Step 3 of Redken's most concentrated system ever. This conditioner provides an all in one solution to address all types of hair damage, even the most processed hair. A little goes a long way! This product is thick in consistency and will coat your hair with less product than your average conditioner. We recommend you start with a dime size amount and increase from there based on your hair type. Made with Citric Acid and Redken's Bonding Care Complex, this conditioner helps reinforce weakened bonds, provides strength repair, intense conditioning and color fade protection.
