Wondering about the Social norms regarding hair length

when did we as a human kind, decided that a person growing a long hair is not a personal choice but, expected.

Does women’s long hair have any purpous on the earth.

men and women bodies are diffent in biological sense, breasts give milk, vigina holds baby and body structure evolved for its motherly needs. but long hair makes no fucking sense. is it there so babies can pull and rip the scalp off, i dont think so.

when did women kind decided to make long hair there identy, and when did man kind decided it doesn’t suit them.

A pair of sissors can cut any hair, if grooming tools existed for men. it sure was available for women. why they didnt cut there hair.

when did men kind as a whole declared, a women having a long hair is sexy.

If long hair was gender nutural, when it becaome not.
