Some cultures consider being bald an honor. Trump and other baldness deniers are just complete weirdos in my book (disclosure ... I'm quite lacking in the "top fur" department ... but hide none of my shining head end!).
Given that it is conditioned by testosterone I have a hypothesis that male-pattern baldness was originally a secondary sex characteristic of adult male australopithecines. A significant element of human evolution has been Neoteny, the retention of more juvenile features into adulthood, and this disrupted the normal timing of the development of the baldness.
