The Schauma dry shampoo is definitely one of the best dry shampoo that you can get to drugstore prices. If you really shake vigorously before each spraying the bottle, it is enough to make many applications and the nozzle is not clogged or no gas can escape. My only problem is the smell. I'm not usually so sensitive but I find the dry shampoo smells artificially fresh and perfume-heavy and will remain long in the hair, so you no matter where you smell goes strong to dry shampoo. I find that rather counterproductive. The fragrance is really anything but discreet.
