Can Head Lice Spread Between Household Members?

Head lice can spread when live lice move from one person’s hair to another person’s hair, most often during direct head-to-head contact. They crawl; they do not jump or fly. Sharing a bed or sitting close together does not automatically mean everyone has lice, so checking people is more useful than assuming the whole household is affected.

Who Should Be Checked?

Check household members and other close contacts when a case is identified, especially anyone who has had repeated head-to-head contact. Use bright light and inspect sections of hair carefully, paying attention behind the ears and near the nape of the neck. Finding a live crawling louse is a useful sign of an active infestation. If you cannot tell whether a speck is a nit, dandruff, or debris, ask a pharmacist or healthcare professional for help.

What About Shared Items?

Transmission through objects is less common than direct hair-to-hair contact. Avoid sharing combs, brushes, hats, hair accessories, and similar personal items while managing an infestation. Focus on recently used items that touch the head and follow their normal care instructions; extreme whole-home cleaning or spraying household chemicals is not a substitute for checking hair.

Choosing a Treatment

If live head lice are found, choose an appropriate treatment and follow that product’s current Drug Facts label exactly. Products can differ in age limits, directions, warnings, and follow-up instructions. Do not treat every household member automatically, combine lice medicines, or repeat an application earlier than the label permits.
