What Causes Head Lice?

5. Sharing Equipment
While direct transmission is by far the most common method, there is also a small chance that somebody can become infected indirectly. This means coming into contact with items that have some lice living on them. It is important to bear in mind that lice can live for up to two days when not on a human head.
This means sharing things like hats and scarves could be harboring the lice. Sharing combs can also lead to transmission, while sharing towels and even headphones can spread the mites. Lice can also end up on the pillow of an infected person, and they might crawl onto the head of a person that uses the pillow afterwards.
