never said global scale... in fact, all of the men from turban wearing cultures actually never cut their hair (hence the turban). When I talk about the middle ages, I'm talking about Europe (do you ever see knights and kings and shit in India or Africa ? ), which then applies to America, because its been colonized by Europeans. And if you dont believe that long hair has been stigmatized, then just look at how negatively long hair is perceived in a job interview and in the business world in general.
