Question

Why does your hair stick up when you conduct electricity?

Answer 1

Hair Doesnt Conduct electricity

Answer 2

Because you hair is all charged with the same electrical charge (can't remember if it's positive or negative) and each strand repels the other strands.  If the charge is strong enough, this repulsive force is strong enough to counteract gravity and repel strands from each other.
