Head lice are typically treated with over-the-counter or prescription lice shampoos, along with a fine-toothed comb to remove nits (lice eggs) from the hair. Some anti-lice shampoos can also be effective. To prevent head lice, it’s important to avoid head-to-head contact, refrain from sharing personal items like combs or hats, and regularly check for lice, especially after potential exposure. Always keep the scalp clean and practice good hair care which can help to reduce the risk of infestation.
