When I used this shampoo it had been along time since tried a clarify shampoo, so I did have a lot of build up of products on my hair. I did not like the smell of this product it had a very chemical smell or like cheap shampoo in a motel. I felt like it did remove the build up on my hair. My hair felt light and soft but a little on the dry side. I would only use this product weekly at the most .
