My take is that nobody will care if you are bald, but with all their tech you can have as much or as little hair as you want. It's an aesthetic choice that's entirely yours, and no matter what you pick it's not going to really attract attention. I mean, who's going to care about your hair when you live next to a temporally displaced Klingon veterinarian and work with a guy who once got to be Q for a day? And even that is just kind of normal?
