There is a difference between dandruff and dry scalp (Brad Mondo has a video about this) I guess depending on which one you have Pureology might work or not. Regardless different things work for different people!Same. Purology hydrate works so well for my very dry hair and sensitive scalp. It's the best shampoo I have tried. I hate the minty smell and the menthol feeling though.
I tried it and it didn't work for me. These type of shampoo work well for my husband too as he's eczema prone on his scalp, but for me they are usually not hydrating enough.
