Head lice are spreading in schools, mainly among children aged 3 to 11, due to close contact, not hygiene.

Head lice infestations are rising as children return to school, particularly among those aged 3 to 11, according to health experts and search trends. Lice, which are not a sign of poor hygiene or disease, spread through close contact and can cause itching and sleep disruption. Nits, or lice eggs, resemble dandruff but are harder to remove. Treatment options include over-the-counter or prescription medications and professional services using FDA-cleared heat and airflow devices. Experts stress prompt action to prevent spread, discourage stigma, and oppose exclusion from school. Regular hair checks and avoiding shared personal items are recommended.
