How to remove semen from hair?

So the other day I kidnapped a man called Zac Efron; I took him to my house and d him. He seemed to be enjoying it and then he released his white fluids onto his own face and hair. Not realizing he did this I shot him four times through the chest so that I could post his head on my wall, but now he has semen dried on his musical high-school face. I can't put his head on my wall like that, all my friends will laugh at me! So how would I remove this semen from his hair? It has been in it for about thirty minutes now if that matters.
