It might be he just enjoys playing with your hair, but it might also be his way of showing you that he likes you. Ask him something like "do you like playing with my hair?" to find out. If you ask that, make sure you tell him you enjoy when he does it or you don't (depending on whether you actually do), because otherwise the question might sound like a "is it really so much fun that you can't stop it?"
That he wants you to notice him probably because he likes you.
How old are you? I mean seriously. And most likely because that is strange.
Well, I think that if a guy touches the hair on your head, then he wants to feel you up, but he knows not to or that he really likes you and your hair.
Not necessarily. He might just dislike her. But if he's playfully mean, or is sometimes nice- then maybe.
he likes you...
She likes him.
playfully poke him back.. he is flirting with her
Well, there are many answers. If you are a girl and the guy pushed your head playfully he likes you as a friend. It could be the same for a boy but girl or boy it could be plain bullying. So if you know the guy a lot and your a girl maybe he's trying to embarrass you so maybe the guy bullies you or they like you.
It usually means that he wants to have sex with you.
He wants to have a sexual intercourse with you
It means you need to tell your parents.
Either it was an accident or he really likes you.
Either it was itchy or he got a BONERRR!!
