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?"
How old are you? I mean seriously. And most likely because that is strange.
Not necessarily. He might just dislike her. But if he's playfully mean, or is sometimes nice- then maybe.
he likes you...
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.
It means you need to tell your parents.
It depends on how he acts if its like he laughs at you or plays tricks on you he might. but if he is physically hurting you its a NO! Trust me there's a guy at my school and i really like him and he is playfully mean to me and all my friends say he likes me.
No, it's actually not bad at all! It may mean that the boy likes you a lot! If he keeps playfully teasing you, it would be a good idea to tag along...if you like that boy of course!
it means they are too shy to admit that they like you
Most likely. because he is actually trying to get ur attention.
It means that that guy really loves you and it's also really bad so don't let a guy do it to you.:)
