Maybe there is a good answer...
but anyway let's say there was an ape-man with very short head hair.... then after a long time basically every single human had long hair (and long beards for the men). For all humans to have it then there must have been selection pressures to have hair that grows to a few feet in length...
Here are some humans that lived in a primitive way:
So why would there be selection pressures for the hair to consistently grow long if most humans are just going to cut it - like in the photo where it is cut very short.... in this picture their beards have been shaved off....
The fact that basically every single human can grow long hair and beards suggests that there must be a very important reason for it.
I get the impression that it is for self-expression - there is a huge amount of variety of hair styles and beards, etc.... though I'm not sure if that is a strong enough selection pressure to affect our ancestors in a way that affected basically all humans....
For me this is an example of guided evolution....
