This was a godsend on my recent trip to Asia. I wasn't going to be near a shower for a day and a half so took the purse size of this on the plane with me and it refreshed my hair brilliantly.
You spray it on to your roots, and brush it through. Science happens (don't ask me what!) and the oil and 'wear' in your hair lifts and can be brushed out, leaving cleaner, less greasy locks behind.
The scent is quite strong, and powdery but doesn't linger badly as it doesn't actually cling to the hair - just give it a general residual freshness.
This product really just degreased my hair and gave it a little volume. A must have for future travelling/camping/sports etc ventures!
i used a friend of mines once, as my hair goes super oily after 12 hours of being washed. and we were going out for the day. super easy to use, no problem. was the first every dry shampoo iv used and found its amazing ^_^
