What does headlice do to the scalp?

Head lice are small, wingless insects that live on the human scalp and feed on blood. They can cause itching, irritation, and sores on the scalp. In some cases, head lice can also lead to bacterial infections.

Head lice are spread through head-to-head contact with an infected person. They can also be spread through sharing hats, combs, or brushes with an infected person.

Head lice are most common in children, but they can also occur in adults. Anyone who comes into close contact with an infected person is at risk of getting head lice.

Head lice can be treated with over-the-counter or prescription medications. Treatment typically involves applying a medicated shampoo or lotion to the scalp. Head lice can also be removed manually with a fine-toothed comb.

It is important to treat head lice as soon as possible to prevent them from spreading. If you think you or your child may have head lice, see your doctor or pharmacist.
