My head itches from lice, what to do? - in detail
Scalp irritation caused by lice requires prompt identification and treatment. Confirmation involves visual inspection for live insects and nits attached to hair shafts close to the scalp. A fine‑tooth nit comb, used on wet, conditioned hair, reveals the presence of parasites.
Effective treatment options include:
- Over‑the‑counter pediculicides containing permethrin (1 %) or pyrethrin with piperonyl‑butoxide; apply according to package instructions, leave on for the recommended duration, then rinse.
- Prescription agents such as malathion (0.5 %) or ivermectin lotion for resistant cases; follow medical guidance for dosage and repeat application after 7–10 days.
- Manual removal using a nit comb after chemical treatment to eliminate remaining eggs; repeat combing every 2–3 days for two weeks.
Environmental control reduces reinfestation risk:
- Wash bedding, clothing, and towels in hot water (≥ 60 °C) and tumble‑dry on high heat.
- Seal non‑washable items in a sealed plastic bag for at least 48 hours.
- Vacuum carpets, upholstery, and car seats to capture stray lice.
Preventive measures minimize future outbreaks:
- Prohibit sharing of hats, hairbrushes, headphones, or pillowcases.
- Conduct weekly scalp checks in school‑age children, especially after contact with known cases.
- Educate caregivers about early signs and proper treatment protocols.
Following these steps eliminates the infestation, alleviates itching, and prevents recurrence.
