Comment on What's the evolutionary advantage of very long hair on human heads?

That’s an interesting take, agreed. But it doesn’t explain why the length… You can still shave hair that doesn’t grow too long. And look dangerous to fuck with

Yes, that is not an evolutionary pressure. Long manes serve the same function in humans as a peacock’s tail or a baboon’s bright red ass.
