I hate the messy spray dry shampoos.  I've tried about 6 different ones, high end and drugstore, and all of them have left a disturbing grayish cast in my dark blond hair.  But this dry shampoo is a sprinkle in powder that works incredibly well. I use the tiniest amount of this powder and it soaks up oil really well but it does take a few minutes to work.  At first the scent is strong but it soon disappears so if you're fragrance sensitive, you'll definitely be able to use Pronto.  It makes my hair look and feel much cleaner and it doesn't give me that flat matte finish like so many dry shampoos.  The small size is deceiving because it takes very little powder to do the job and I'll bet there's not much actual powder in the sprays and that all the room in the can is taken up by nasty propellant.  So this product is not expensive to use at all.  I've had the 1 ounce size for several months, even though I use it a couple of times a week.  It also comes in a larger size, which is more economical.  I know that Ulta carries Pronto and if you buy it there, you can return it if you don't like it.  However, I'm willing to bet that you'll like it as much as I do.  I definitely prefer the sprinkle in powder form over the sprays.  Today, for example, I used Pronto and after 20 minutes there was no residue left.  I just worked it in like regular shampoo and POOF!, 20 minutes later it had disappeared.  I had some nice volume and my hair still had shine.  I really like everything about this product and will keep it stocked from now on.  It's by far the best dry shampoo I've tried and I see no need to keep looking.  If you want cleaner looking hair without having to shampoo, I suggest you try this product.  I definitely recommend it.
