What they need to do is make it so that the flared collar can be folded down if desired, and either make it fold down for hair that will clip, or alternately, give the player a command to use that switches between flared and folded as needed. It would also work for metal armor in that you could reason that for longer hair you install a different shoulder/neck piece that lays more flatly than the many flared neck/shoulder protectors. This would resolve a lot of hair/gear clipping issues.
