Acidic Bonding Concentrate Leave In Conditioner is Step 4 of Redken's most concentrated system ever. This leave in conditioner helps repair strength and recondition hair while reinforcing weakened bonds even in the most processed hair.
A little goes a long way! This product is lightweight but creamy in consistency and will coat your hair with less product than your average treatment. We recommend you start with a dime size amount and increase from there based on your hair type.
