Humans have to cut their hair because it is an amazing indicator that you are not currently struggling with problems most intimately related to natural selection (base level survival). No matter the culture, people style their hair. It can be any style. It will vary by culture. But all cultures have very advanced styling methods for hair. If you don't style your hair -- you are seen as someone that can't take care of him or herself (i.e., "homeless" "starving"). So there was high sexual selection for people that styled (and hence "cut") there hair in some way.Why do humans have hair that needs to be cut?
