Dandruff or head lice?

So I went to summer camp for a week. When I was driving home I got a call that a girl in my cabin had head lice. I have always had dandruff and when my mom looked at my head there were tiny white specs. The only thing is they were bigger than my normal dandruff specs. They were very easy to pick or comb out. I was with that girl every second of the week. Is it head lice or normal dandruff?
