Treatment for lice on the head includes medication and other treatments, and patients should follow their doctor’s instructions. Lice are parasites that usually move between the scalp and hair. Lice feed primarily on human blood, and their bites produce red spots, pimples, itching, and an ant-like sensation when they crawl. Lice can lay their eggs on the proximal part of the hair, and the eggs can hatch to produce adult lice again, recurring some of the symptoms of scalp itching. Lice are mainly transmitted through close contact. Sharing combs, pillows or hugging each other can lead to lice transmission. Lice on the head can be treated with medication as prescribed by the doctor, including 0.3% pyrethrin and permethrin. Pyrethroids have a relatively strong killing effect on most head lice, and a better result can be achieved by wearing a shower cap for a few hours after topical application. Permethrin has similar insecticidal effects to pyrethroids and is used in a similar way, but is generally not recommended for children under 6 months of age. Avoid direct person-to-person contact transmission during treatment. The comb, headband and hat used by the patient should be sterilized in a timely manner, and attention should be paid to personal hygiene and household environmental hygiene on a daily basis. If you feel unwell, you should go to the hospital in time to avoid delaying your condition.
