And yet, the original elezen-only "new" hairstyle (the long, parted hair with the single braid in the back) is by far the most common hairstyle I see, yet when it was elezen-only, elezen barely wore it. People pick favorites. If they released all of the hairstyles to everyone, you bet you would see 3 or 4 way way more than the others, because people would pick their favorites instead of choosing the best out of the hand dealt to them.
Personally it's just hair so I think it should be open to everyone. Though I wouldn't be opposed to hairstyle with actual substance like a geisha updo for au ra ladies or a samurai top knot for au ra men, or a French twist for elezen ladies or a pompadour for highlander men. Something with actual like cultural references to the races or actual meaning instead of just "Oh yeah apparently only elezen women can cram 40 pins into a generic (as opposed to iconic), flat, bob hairstyle." Like if they are going to give everyone something unique, make it worthwhile, instead of just slapping a restriction on something that was plain/simple to begin with.
