Rub-Out Dry Cleanser is a dry shampoo spray with a powdery scent that’s overwhelming. The spray deposits a sheer layer of powder on the hair and scalp to absorb dirt, oil and product build-up. You are instructed to gently rub and brush the hair after spraying to ensure even distribution. The cleanser leaves hair refreshed and free of powdery residue. While this product is not a substitute for regular shampooing, it gives the hair a lift in between washes.
