Once infested with head lice, it usually takes a week for itching to develop. Itching is usually the only symptom, but scratch marks may occur, especially on the back of the neck. It is easier to discover and confirm head lice infestation if you actively look for them – so be vigilant if head lice are in your environment. In such cases, the entire family should be carefully checked for two weeks. Infected individuals should be treated simultaneously to minimize the risk of recurrence.
People who have had lice in the past will immediately experience itching. However, many people experience no symptoms, which increase the risk of spreading.
