yes that is one thing, but often times the problem is the social stereotype to having "no hair" and what it is meant ot mean in society.
for example kane from c ommand and conquer is bad (not unatrive, just seen as bad), his social reason for being bald is he is an evil dictactor trying to take over the world.
if he had hair he'd be a normal guy, same with willis its like if your bald its meant to mean something different to normal people, that is why when he is bald he is doing something, when he is in wig he is normal guy, if your bald and your in the media (high ranking tv show, movie) there better be a damn good reason for you being bald (villian, anti hero, middle aged hitman - willis statham,general weakness ala george constanza,your a monk, a senior citizen etc.)
it's like how in lost they had about 30+ male characters, they all had hair becuase they were young adults (19-40), only bald man was middle aged locke at 47 and was protrayed as the "wierd" one socially.
so rather than being conventionally unatractive, its more a social stereotype and not fitting in with what the media expects you to have, hair.
overall the media avoids pre-mature male pattern baldness almost indefentely, ocasioanally reseved for certain men (like all 4 or 5) but they are all 47+ and have somethign "off" about them and that's it. :shakehead:
its clear by society that we are unwelcome, unless we are 47, look great with "it", and are dressed a certain way, carry guns, know kung fu, and have blown something up recently.
