Why do most girls look the same these days?

what i mean is, most teenage girls all have straight flat long boring hair and they all have the same hairstyles with flat hair and bangs, what happened to veriaty in the world? if i had long hair and was a girl, i'ddo crrazy exciting things with my hair... miltiple plats, curls, bows hairclip it up nicelyy, maybe have a nice quiff, oh there ae endless possabilities of things to do with long hair and everyone insists on just leaving it straight and flat real flat, like straightening it fifty times a day and down in no interesting hairstyles, boooring! victorians had better hairstyles. and also curly hair seems to have completely fazed out, even black people straighten their hair! what's with that, in my opinion curly hair is way better than straight hair in the first place so there should be some straight haired ppl and some curly haired not allllllllll straight hair
