Headgear is used in some combat sports, including Olympic boxing. It makes the head a bigger target, which means the head gets hit more. Those strikes may be less severe, since they're cushioned. But taking more hits is bad.
There certainly are sports that ban head strikes. Certain forms of karate, for instance. Fight fans _like_ seeing heads get punched, and they like seeing knock outs. There's not currently a very big market that wants to see fighting without head strikes.
