I will try to help you.  :D
So, you know that objects with the same charge REPEL each other. On the other hand, objects with opposite charges (positive and negative) ATTRACT each other. Since you are putting a balloon on your head, and your hair tries to ''touch'' it by standing up, what can you say about the charges of the objects? 
Sorry if I can't tell you directly. Pooja195 has warned me not to give direct answers, even though I gave a bit of explanation for a problem. I want to make sure you understand this.  :D
