If you're asking "What sort of helmet?" the best answer is "How much of your head do you want to protect?" If you don't like your head, don't wear one at all and chances are you'll have a whole new and interesting head to keep you entertained sooner or later.
As Astaren pointed out a helmet's useless if you've ripped the skin off your hands and can't remove the helmet, or taken a foot off and can't walk over to pick it up again. Jacket, jeans (you can get jeans with kevlar in them from bike shops), boots with ankle support, and gloves all make sense.
There's folks who'll decide you're uncool for wearing protective gear, but you'll look a lot cooler than them when they're all stitched back together, missing a few bits, and eating their steak through a straw.
