How about wearing a good wide sweatband around your head under your helmet? That might help keep the sweaty head thing in check. If your hair is short (like mine)- you have less to fuss over to get it looking normal again. I never get any "helmet hair" that can't be fixed with a hand or washcloth quickly run through it. About just running a damp washcloth over it and then a brush and/or dry washcloth?
