I suffer with a dry, flaky scalp. I use this scrub once a week/fortnightly. I really feel like it cleans my scalp and removes all flakes.  You don’t need to use a lot, but I hold my head upside down and really work it into the scalp, massaging my head. I then leave it for a few minutes to work in, and rinse out.  Follow with usual conditioner.  Fantastic product, will definitely purchase again. Worth the money!
