I am not entirely convinced. First it is extremely difficult to apply and when I tried using it the first time. When I applied it, the product was just clumping together, falling off everywhere and creating a mess in the bath, and it was also difficult to wash off. The 2nd time I tried it, I mixed the product in a jar with water and mixed thoroughly first. It worked better because I could apply it, it lathered a bit, it felt I was able to clean my scalp better, rinse it off and there was no mess either. Did my hair feel any cleaner? No not really even though I truly suffer from scalp build up, dandruff and this product did not really make any difference.
