I have tried a couple of other dry shampoos, smaller bottles and cheaper bottles. Not worth it.
This one is phenomenal. The Schwarzkopf one smells like flyspray and leaves an immediate white cast where it is sprayed, and barely works. This one smells lovely, you have to really spray it for a while/incorrectly to make your hair white, and it leaves it feeling soft and clean. It makes the hair have a nice 'cool' feeling which is great. It is totally worth it just for the smell and feeling, but it definitely reduces the amount of oil in my hair and extends my hair's life for at least a day before I need to wash it again.
I use this product even when my hair is freshly washed just for the pleasant smell!. It's great when I don't have time to cleanse my hair, it makes it feel nice and clean and takes away the greasy appearance. Also cute pink packaging, you need to try this.
