Amika Perk Up Dry Shampoo was formulated without talc, aluminum or any harmful ingredient that can be risky for the health. It aims to give your hair ideal volume, but we did not felt such a huge effect of this on our hair’s volume. The scent didn’t quite sit well with us as well. However, we like that it absolutely leaves no white residue and makes the hair oil-free even without washing it for up to 3 days.
