I have random coarse hairs that stick straight up on my head 1-4 inches, and are almost impossible to tame. I rub a little of this on my fingers, coat them, and slick them down onto my hair. Most of them do actually stay down with this product, unlike any hairspray I have tried. It doesn't make my hair greasy, either.
This stuff smells really, really good. The downside is that it seems to make a complete mess of my hair when it gets longer. I have some thick hair and it just seems to... Get greasy, I guess. It's just unpleasant to use for me personally, but I think it'd be beneficial for someone with finer hair.
