Why is his hair standing up straight after going down the slide?

Back

The slide caused friction making each of his hairs have a like charge, which repel each other.

When you go down a slide, electrons move from you to the slide. This causes your hairs to have more positive charges. Objects that have the same charge repel each other. So, each of your hairs tries to repel its neighbor.
