Women having long hair is an artifact of sexism.
My wife insists our daughter should have long hair, but she hated getting it combed out as combing is painful. I told my wife we should shave her head. My wife disagrees.
Women with long hair are easier for men to control as a man can just grab a handful and drag a woman around. Long hair takes many times longer to maintain each day than short hair does.
I think there are attractive hairstyles that are shorter, and should be used.
