This is by far the best dry shampoo I've ever used. It soaks up oil VERY well, and definitely increases the volume. My favorite part about this product is that your hair still feels normal after you use it, there isn't a ton of product residue leftover as with most dry shampoos. Great product, I would definitely recommend it if you can afford it. I got 5+ uses out of my sample size, so it goes a long way!
