what look are you going for? if you want a drier look, that still has some good hold to it use American Crew Fiber. If you want more of the gel look, where it is just firm hold, won't move the whole day, then use American Crew Structure- its like a mix between a gel and a wax, strong hold, but adds thickness instead of just pulling all your hairs together and making you look balder. you can get them at any salon.
just out of curiousity, and not to hijack your thread, but has anyone tried using the American Crew thickening lotion? does it work well?
