I've gotten to be a huge fan of dry shampoo, and am presently using the powder (as opposed to aerosol) form of the Oscar Blondi product available from Sephora. Really fantastic when I'm on the road, and particularly great for sprucing up after a red-eye or TATL. My only peeve (and it's a small one) about the Oscar Blondi product is its scent: lemon-y, sort of like lemon verbena (which is the same as lemon Pledge). I'd prefer something a bit more neutral, more generically soap-like.

Any other experience out there?
