Be careful if you have dry/sensitive hair/scalp....this shampoo made my hair feel "squeaky" which was very unpleasant. I applied the matching conditioner which did nothing to help. My hair was frizzy and dry and my scalp was very itchy. For reference, I have fine, long, unprocessed hair that I let air dry. I definitely expected more from a brand developed by a dermatologist.
