Powder shampoo is something completely different from regular dry shampoo. Powder shampoo has the same purpose as regular shampoo - that is, to wash your hair. It just comes to you in powder form. Why should you give it a chance and how is it better than classic shampoos? The preparation of shampoo can be very quick and simple - just mix a little with water and apply to the hair. But it can also be a very sophisticated part of your hair ritual that you can tailor to the exact condition of your hair and skin. You can dilute powder shampoo with whatever your hair is craving at the moment.
