WHAT THE TEST MEASURES
About This Assessment
Do I Have Lice Quiz - Symptoms and Signs
Could an itchy scalp or unusual specks be related to head lice? This free, quick self-check reviews observable hair findings, symptom patterns, and recent exposure. Lice crawl rather than jump, and itching alone cannot confirm them. The scores are unvalidated reflective summaries—not diagnostic, clinical, or legal cutoffs. Check with a pharmacist, clinician, or lice specialist for confirmation, especially if you find a moving insect, symptoms persist after treatment, or the scalp has spreading redness, warmth, pus, swelling, fever, or significant pain.
