Whoops. I almost forgot, one other trick if all else fails, just move the hair into a good position with your x,y,z trans and when it's prefectly adjusted on the head, just select the hair and do Figure: Lock Figure. That way, when you pose the model, or apply a pose, the hair won't fall off the head. Just remember to unlock it if you need to do anything else with it, like move it or something.
