Query: Dissapointed with result

My hair stylist recommends not shampooing my hair every day to keep my red hair red longer after a dye job. However, since my hair is quite fine it looks greasy if I don't shampoo. I have tried baby powder in the past but it ends up looking white and going everywhere. I bought this product in the hopes that it would prevent greasy roots and allow me to shampoo every other day. I was dissapointed because it didn't have the effect I wanted. My hair still looked greasy and dull and the only difference was that it was bright red at the roots from the spray.
