Some people have hair that grows really fast, but some people have hair that is very slow. In this game, the kids' hair grows extremely fast and it's up to you to keep it cut before the time runs out and all the kids leave. Be careful when shaving their hair too because if you put the shaver to their head after you've shaved them, their head will bleed and they will scream. If you do that, you will lose points, so make sure you pay attention. All you have to do to cut their hair is to click on their heads. Good luck!
