Since the dawn of humanity, hair - it's length, color, & configuration has been a surprisingly important and divisive issue. I can remember when the phrase "Blondes have more fun." was not just an advertising ploy, but the motto of a generation! "HAIR" was not just on your head, it was on Broadway! But hair was always something to fight over, to idolize, or to belittle others about.
I truly believe, one of the great achievements of the millennial generation, & of alt-culture in particular is that you have rendered all argument about human hair completely meaningless!. The endless variety of hair colors, and the frequency of how these colors change - The plethora of hair styles, be they long, short, or none at all, have brought unprecedented freedom to all human beings. Now, if we could just apply the same principles to human skin & its color, we will really have something!
