i got a free sample of some elasta QP sheen spray and i'll tell you the verdict right now: LOVE IT!
i use this usually before going out and always when i do pin curls. it is not heavy nor oily and leaves a GREAT sheen. go get yours. i dont know what the regular price is because i haven't run out yet (a little goes a long way). you can probably get it for no more than $7.
