Best friend being bullied??

Do try to make your friend as comfortable at school as possible. If that means helping her get her hair styled, or simply going way out of your way to be by her side so when the bullies call her names, you will be there to stick up for her. Reassure her that the bullies don't have a clue of what they're saying, and that your friend truly is beautiful.

If she's personally not bothered about it, then don't make it a big deal, like everybody else. Her friends making a big deal about it may well make her feel uncomfortable, whereas she may be able to handle everybody else's mindless drivel. Talk to her, don't assume. She needn't bow down to the narrow minded opinions of others, if she likes her hair, then she likes her hair!
If she is genuinely upset with peoples comments then, comfort her, but don't forcibly suggest your idea. It sounds like a lovely thing to do for her, but it can also be perceived as you agreeing with the people who are bullying her that her appearance is odd. That's not a nice thing to hear from a friend.

I think if she's not bothered by it (or not showing that she's bothered by it) then maybe the best way to help is to just offer the odd compliment here and there. Even if she think's she's not bothered it's gonna cut her down in some way so a nice compliment from a friend might help that Also is there a way you can get her away from these people? That way you stop the situation entirely. Like maybe at break and lunch you two (and your friend circle if it's appropriate) could sit outside instead or take a different route to class. Not ideal, but a start I guess

I think you should have your mom cut her hair and make sure you stand up for her when you hear things like that and make sure she knows you are there for here whenever she needs you.

The thing to do here is not to change her haircut or try to improve her style so people will stop bullying her.... She has the right to be herself and be respected even though some people won't agree with the way she dresses or something like that. Bullying is usually not about the bullied person, but the bully itself. When the bullies feel powerful and popular by bullying someone else, they will keep doing it until they find out that they don't have as much influence or power as they had when they first started the bullying. If your friend can defend herself, the bullies will stop, cause they won't feel the power anymore. But the thing is... She can't defend herself right now and that's exactly what makes bullying posible. As her friend, you are one of her most powerful weapons against this.. If you and your friend can find enough support from other students (and ok, I know this is not easy either) that would certainly help you to fight against this... If the bullies don't get the attention they want by bullying someone, they will stop. But the attention they want is not the attention of the victim, so ignoring won't solve the problem either. But if you can make the other students take an anti-bullying attitude, the bullies won't get what they want and will stop. In case you can't find enough people to support you and your friend, talking to directors or teachers in your school can also help... Try to choose someone in your school that doesn't seem to be too impulsive and that usually listen to the students and really care about them... I bet that if you find someone like that inside your school, you can figure out how to deal with this issue in the best way you can. Hope that helps! :)
