I love Tresemme, I think their products are of great quality when one compares the prices with other brands on the market. This dry shampoo is no exception. My hair gets oily really quickly, and if I don't wash it everyday I am left with terrible looking roots (eeek). Enter Tresemme Dry Shampoo... I spray it into my roots and leave for a minute before combing my hair thoroughly. I am given an instant boost of volume along with fresh (looking and smelling) hair until my next wash. I even spray it on when my hair is clean, just for that added volume and freshness it gives. I would not recommend to be used after more than one skipped shampoo.
