Do lice like dirty hair? Lice are tiny, wingless insects that live on the scalp and feed on human blood. They are spread through direct contact with an infested person or their belongings. Lice are not picky eaters and will infest any hair type, regardless of its cleanliness.
While lice prefer dirty hair, they can also live in clean hair. In fact, lice are more likely to infest clean hair because it is easier for them to move around. Lice are attracted to the oils that are produced by the scalp, so they are more likely to infest people with oily hair. However, lice can also infest people with dry hair, especially if they are not able to find a suitable host with oily hair.
