How does laser hair removal work?

Hey, I have a bunch of question about laser hair removal, namely: how does laser hair removal actually work? Like is it burning off each individual hair or does it seal up the follicle or something? Also what do they use to do the removal? Will I have to do anything special to prepare for the procedure?
