Don’t forget the terrible dynamics at play between having a full head of hair (hair density in terms of grown follicles per unit area to be technical about it)

Don’t forget the terrible dynamics at play between having a full head of hair (hair density in terms of grown follicles per unit area to be technical about it) as an obvious signal of youth/health while there’s also the common perception that bald men are better lovers, which is backed up by research and makes obvious sense since the hair loss is (outside of more specific circumstances) caused by testosterone slowly killing the hair follicles on the scalp and higher testosterone levels being well associated with mate selection not just in people but across primates in general!
