How to treat the head for lice at home? - briefly
Use a permethrin‑ or pyrethrin‑based shampoo or lotion, follow the label’s application time, then remove all nits with a fine‑toothed comb and repeat the process after 7–10 days to eliminate any newly hatched lice.
How to treat the head for lice at home? - in detail
Effective home management of head‑lice infestation requires a systematic approach that combines chemical or natural agents, mechanical removal, and environmental hygiene.
Begin with accurate identification. Adult lice are 2–4 mm long, brownish, and move quickly on the scalp. Nits appear as tiny, oval, white or yellowish shells attached firmly to hair shafts within 1 cm of the scalp.
Select a treatment method. Options include:
- Over‑the‑counter pediculicides (permethrin 1 % or pyrethrin‑based sprays). Apply to dry hair, follow label instructions for exposure time, then rinse thoroughly.
- Dimethicone‑based lotions that suffocate insects. Apply to saturated hair, leave for the recommended period (usually 10 minutes), then wash out.
- Oil treatments (olive, coconut, or tea‑tree oil). Saturate hair and scalp, cover with a plastic cap for 30–60 minutes, then comb and wash. Oils may be combined with a small amount of an insecticide for enhanced effect.
After chemical or oil application, perform meticulous combing. Use a fine‑toothed lice comb, working from the scalp outward in 1‑inch sections. Remove each louse and nits, wiping the comb on a tissue after each pass. Repeat combing at least twice daily for seven days, then again after 10 days to capture any newly hatched lice.
Environmental control prevents re‑infestation. Wash all bedding, clothing, and towels used within the previous 48 hours in hot water (≥ 130 °F) and dry on high heat. Items that cannot be laundered should be sealed in plastic bags for two weeks. Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags immediately.
Monitor progress. Inspect the scalp every 48 hours. Absence of live lice for two consecutive examinations confirms success. If live insects persist after two treatment cycles, consider a prescription medication or consult a healthcare professional.
Maintain preventive habits. Avoid sharing combs, hats, or pillows. Encourage regular head checks, especially in school‑aged children, to detect early signs of recurrence.
