Honestly though in the small 3rd person it doesn't make a whole lot of difference. Now if the game had a lot of close-up cut scenes like DAO, the hide helmet feature would be a must. With this game, maybe not as important but ... why not. If you go to all that work to give your girl wavy red locks you might as well see them right?
I'm going to be a mean ol' jerk again and say that "hide helm" is really not important, especially when there are loads of other, way, way, way, way, way more important things that need work.
I'd put this idea on the "add in a patch sometime after the game gets released" pile.
