Do Lice Prefer Clean Hair or Dirty Hair?

Head lice do not indicate that a person has dirty hair or poor hygiene. They can affect people with clean or unwashed hair. The main factor in getting head lice is exposure to lice, most often through direct hair-to-hair contact, rather than how often someone shampoos.

How head lice spread

Head lice crawl; they do not jump or fly. They most commonly move between people when hair comes into direct contact. Sharing personal items such as hats, combs, or brushes is a less common route, but avoiding shared hair-contact items is a sensible precaution.

What cleanliness can and cannot do

Washing hair more frequently is not a dependable way to prevent or treat head lice. Ordinary shampoo is not the same as a product labelled for head-lice treatment. Likewise, a person should not be blamed or embarrassed if lice are found. Head lice are a common issue and are not a judgement about personal cleanliness.

What to do if you are concerned

1. Inspect the hair and scalp in good lighting, working in small sections.
2. Check close to the scalp, particularly behind the ears and around the nape.
3. Look for live crawling lice and attached nits; itching alone does not confirm an infestation.
4. If lice are confirmed and treatment is appropriate, read and follow the current Drug Facts label for the exact product.

Do not use household chemicals or home-remedy mixtures on the scalp. Do not increase treatment frequency or combine lice medicines unless a qualified healthcare professional tells you to.
