I LOVE this stuff I mean it has finally set me free from having to shower EVERY morning.  Let me stress that I have tried so many other dry shampoos and it did not help or made my hair feel gross.  I bought this the first time to give a try when I was traveling for almost 24hrs my hair would get so oily and a little bit of this was all I needed.  I have dark hair and the powder is white so yes if you use a lot you can see it a little bit, however if you take a few min to work it in you cant see it anymore!  It is a little pricey but for me it is well worth it, I NEVERRRR thought I would be able to go a day or 2 without washing my hair and looking disgusting and was so jealous of all my friends who were able to do that but now I can! Saves me so much time in the morning not having to blow dry and style every day.  It's a really light weight powder and almost has a bit of grit in the powder which makes my hair feel clean and freshened while giving it lift.  In my opinion this is what makes it better then any other because it does more then soak up oil.
