I don't. And I know for sure my dad wouldn't of let me date someone with long hair when I was in high school. (not assuming you are in high school just saying when my dad had control of my dating life I was in high school)
There is a reason there is a song called "Get a haircut and a good job".....
It depends on the person, im 18 and my friends and i all love the long hair. my boyfriends hair is at his shoulders with the flippies on the end, sooo cute!! when i met him thats the first thing i liked about him, then i saw how sweet and caring he is, and now we've been together for a year :)
It depends on the look your going for. as long as you don't let it get too long or cut it too short I'm sure girls would love it both ways. do what you like. hairs something u can use to express yourself:) ask close girl friends and see their opinion on it or the type of girl you wana try to impress.
It all depends on the girl. Each girl has there own opinion and sense of style. Don't change yourself to impress any girl, because if you do that, then their probably not the right person to date or be friends with. Hope my answer helped! :)
