In such a case, clearly, "bald" is not negative.Baldness is usually implemented by television and film writers as a sign of premature aging, poor morality, or just general weakness. But occasionally, baldness instead indicates just how awesome a character is, usually representing leadership or over-the-top manliness. Bald Black Leader Guy is a popular subtrope since, for some reason, black men in leadership positions are almost always bald in fiction.
Yes, I agree. I am in a male quartet, and one of them invited us to his house. I told my wife, 'Nick has invited us over to practise.' As she doesn't know who I mean by Nick, I say, 'Tall. Wears colourful trousers. Bald.'Even in reference to humans, it doesn't have to be negative. It can be simply factual. How else are you supposed to describe someone who's lacking hair? Hairless sounds even worse that bald, if you ask me. I guess you could say "the guy with the shaved head," but only if his head does in fact appear to have been shaved.
