Gene Roddenberry had some great ideas and some not so hot.
I'd say one of his worst ideas was that a beautiful woman in TMP should be bald.
I thought that was brilliant. Persis was far more stunning without hair than she was with it. It wouldn't have been so with most women...
Just watched TMP the other day and thought the same thing. If she had had hair it would have made the character average. By being bald she was unique and different and stood out.
