[LOTR] Why don’t royalty ever wear helmets during battles? Aragorn, Boromir, Elrond, Legolas, etc. never use them. Even Theoden ditches his quickly. Is it a cultural thing?

It seems like it would keep them all a lot safer.

Many of the people that you named are leaders who, in addition to actually fighting, are also important for maintaining the morale of their men. They can do a better job of that if they can be clearly identified, which is easier without a helmet. As for Legolas, a helmet might interfere with his archery.
