Head lice are very tiny and you won't know the moment they climb on to your head. No itching or scratching for days, even weeks. All the while they are laying 6-8 eggs every day. After a week these start to hatch and 7 days later these new born lice can start adding their own eggs and you probably still haven't felt a thing. By the time you get the first itch they will have laid a lot of eggs and plenty will have hatched so the first time you look you find an awful lot of little visitors.

Head lice do not hop, jump or fly. They migrate through direct contact with an infested person and their belongings.

By contact with an already infested person. Contact is common during play, at school, and at home (slumber parties, sports activities, on a playground). Headlice are highly adapted to live on the hair and scalp of humans. However, although the human scalp can provide them with feed for life, headlice are vulnerable to inbreeding. So, because outbreeding is a requirement for survival, this appears to be the reason for the strong urge to disperse onto other heads. See similar questions...
