I have thick long hair and a very flaky, itchy scalp. This is the first dry application scalp treatment I have used and yes it did improve my flaky symptoms but it never fixed the problem. I wash my hair maybe twice, max three times a week, and the flakes/itchiness would always come back. I enjoyed the dry application more than I thought I would - definitely made washing my hair easier - only downside is the amount of product you go through is a lot more than normal wet application shampoo. Overall smell was mild and essential oil scented but not amazing. Didn't work for me and expensive for how much I got out of it.
