Also, there's this gem:
At a press conference about Star Trek: The Next Generation, a reporter asked Star Trek creator Gene Roddenberry about casting Patrick Stewart, commenting that "Surely by the 24th century, they would have found a cure for male pattern baldness." Gene Roddenberry had the perfect response.
"No, by the 24th century, no one will care."

I’m bald and although I’m blessed with a great skull shape, and being blonde haired also works to my advantage, I would lie if I said I wouldn’t be more attractive with hair.
The very premise of the show is that humans found a way to mostly move past the worst parts of their nature. Not just in Starfleet, but in general.
At least wrt. outside differences, I suppose it gets easier in a world full of "human with rubber forehead"-looking aliens.
Basically we had to hit our lowest point before we could get better.
