I'd like to see a variety of hair styles as well. Though I've already mentioned this once its not going to matter once you find a helmet. Which is why I'm in favor of a invisible/hide helmet option for the game. As found in the first Mass Effect game.
I was bummed out while playing DKS that I either had to choose between completing an armor set or seeing my character's hair. Not much point in giving character customization if its going to get covered.
