I do love this product. It works really well, rubs in and disappears, and makes my hair look fresh. I just wish it wasn't such a pain to apply. I like to use more than they suggest, so maybe that is my problem, but it is hard for me to get it "all over" my roots, especially in the back.
But I can tell it is going to last much longer than a can of aerosol dry shampoo, so that is a definite plus.
