I got a can of Not Your Mother's Clean Freak Dry Shampoo courtesy of Influenster in my VioletVoxBox for testing purposes this is my opinion: 

I LOVE IT! ♥ So I went a couple of days without washing my hair, my roots were quite oily so I decided it was the perfect time to try out my new NYM Clean Freak Refreshing dry shampoo. It comes in a can kinda like spray deodorant, you just spray it generously on your roots, it sprays on white kinda like a powder, then you just brush it through your hair and Wa-la, amazingly dry and oil free hair! I was impressed with how well this worked and it had a pleasant smell. This is an awesome product and I can't wait to try more from this company! The only thing I didn't like was that it left my roots looking a bit grayish in color, I felt as if though it changed the color of my hair a bit, but the more I run my hands through it that is going away. Give it a try!!!
