I can't go a week without dry shampoo! I have tried most brands. This one is not that different when compared to other brands, they all get the job done. However I do keep on repurchasing this specific brand as it the price is great and Tresseme is a trusted brand. The other thing about it is that the residue left behind is much less than with the other dry shampoos on the market. I am very satisfied with this product!
