Detoxed and tangled
I found this definitely removes build up. I use a lot of dry shampoo and hairspray on my fine, extremely oily hair and this shampoo really gets it squeaky clean, but I need to wash and rinse twice. The only problem I had is that it left my hair very tangled and knotty, which I never experience with such oily hair! Have had to use way more conditioner than I normally would!
