Head lice is very contagious – especially when the person who has lice has had it for a long period of time resulting in a severe infestation. Lice have been around for thousands of years and they have managed to last by moving from head to head. If you put a child with lice near another child, chances are fairly good that at least one bug from the infested child will move on to the other child's head. If a severe infestation is present, the hair will be crowded with nits, so lice will try to move on to another head. When another available, presumably less crowded, head of hair shows up and is within reach, live bugs will happily travel to the new head. Why not? A non-infested head means less competition for a feeding spot for the newly arrived lice.
