I've lurked for a little while and heard a few mentions of White Sands Hair Spray.
I found this video of it used on Youtube:

Check out in the start of the video how it causes a small amount of hair to stick straight up; seems pretty good.
It's probably pretty expensive, think it'd be worth the extra cost?
