Head lice are small, wingless insects that feed on human blood. They are spread through head-to-head contact, or by sharing hats, brushes, or combs. Head lice can cause itching, irritation, and sores on the scalp. In severe cases, they can also lead to hair loss.
Fortunately, there are a number of effective ways to combat head lice. One common method is to use over-the-counter lice shampoos. These shampoos contain insecticides that kill lice and their eggs. Another option is to use a lice comb. A lice comb is a fine-toothed comb that can be used to remove lice and their eggs from the hair.
