I love Shu products, and I really wanted to like this! I had been using a dry shampoo prior to this purchase but thought this looked like a great alternative. I think it might have worked if my hair were shorter, but for me, this didn't add a lot of volume. The application was awkward for me as well. I could never really tell how much I was applying. I ended up pushing the button a LOT of times and didn't feel like there was a noticeable difference in volume. On the plus side, it didn't leave my hair sticky or stiff like dry shampoo can do. I'm going to keep working with this product; maybe if I work it more with my fingers after application that will make a difference!
