It matters if the hair style fits her head, or compliments her face.
Hair that is long can be a nuisance. Plugs the drains and stuff. Costs a lot of money for all the hair products and that kind of thing.
Bangs are kind of cute I guess, but it can look teeny bopper. Pony tail is for a young girl. If they make their hair do things unnatural it can start to bug me. If they are obsessed with combing it and flipping it a lot that is also irritating.
I guess I prefer short hair that works for active outdoor things.
