I have fine, limp asian hair that gets greasy overnight. I have tried about 4 different dry shampoos and while most do an OK job, this one is definitely the best. However in saying that, my hair can get so greasy I still have to use quite a lot of this before I feel like I can venture out without a shampoo.
I have black hair and no matter how careful I am I still manage to give myself grey patches so the next time I repurchase I will try the brunette version.
I finally got around to trying this out and I must say i'm really pleased with the result. I have VERY thick hair and it gets greasy very quickly. i did have to use quite a bit in my hair but i do have heaps of hair so that's to be expected. it made my hair feel lovely and fresh and stayed that way till I next washed my hair. i also found it gave me some volume at my roots so that was a pleasant bonus :)
