I don't see why men debate about this. Patrick Stewart is the hottest old dude around. And Skinner from the X-files was incredibly sexy. Why do men cling to thinning hair and on occasion do horrible things like grow ponytails with the remaining dregs of their hair. Just shave it off! Much more attractive.
I love a good bad toupee! I followed a stranger around Tokyo for 15 minutes because I was so captivated by his atrocious wig. I got completely lost, but it was worth it.
