I've tried MANY dry shampoos and this one is my favourite. It leaves no residue, as long as you work it in with your fingers and brush. The pressure from the can is high so it reaches all around your hairs and to the root easily; only a few short bursts are needed. It can negate shininess in your hair (depending on how much you use and if you spray on top or under your hair), so it works well as a texturiizer as well. If you used too much, it can flake off on your shirt, so be careful. The cons are the price, especially since one can doesn't last long, and the smell--It's not particularly bad, it's just strong and lingers all day. Also, make sure you shake well between sprays, or else you're left with product in the can at the end that won't come out ( you can feel liquid inside when you shake it, but nothing comes out).
