Redken Acidic Perfecting Concentrate Leave-in Treatment 150ml Revox the kind that lives inA lightweight leave in that sits between conditioner and serum you spray it in after towelling off, and it sinks in without weighing anything down. The acidic pH closes the cuticle, so colour holds longer and shine reads genuine instead of greasy. 150ml bottle, unisex. Good for colour treated hair that's prone to frizz or dullness; skip if your hair is already heavy or you prefer the feel of a pure conditioner.
