Dove Brunette dry shampoo

Let me tell you, I love Dove products and have used the unscented dry shampoo from Dove before. Last time when I was in the store I decided to try the brunette dry shampoo. I used it a handful of times. And I swear I like I did nothing to my hair, there has been no effect what so ever, my hair looked exactly the same. At least with the unscented I had some gray colouring but here there is no effect at all. I will not be buying this again
