How to remove lice from an adult? - briefly
Use an FDA‑approved pediculicide (shampoo, lotion, or spray) applied to dry hair, leave it on for the recommended time, then rinse and comb the hair with a fine‑tooth nit comb to remove live insects and eggs; repeat the process after 7–10 days to catch any newly hatched lice. Clean personal items (combs, bedding, clothing) by washing in hot water or sealing in plastic bags for two weeks to prevent re‑infestation.
How to remove lice from an adult? - in detail
Lice infestations in adults require a systematic approach to eradicate the insects and prevent re‑infestation. The process begins with accurate identification, proceeds through treatment selection and application, and ends with environmental decontamination and follow‑up checks.
First, confirm the presence of live lice or viable nits attached to hair shafts close to the scalp. Use a fine‑toothed louse comb on wet, conditioned hair, inspecting each combed section for adult insects and viable eggs. Remove any visible specimens and record the infestation level.
Next, choose an appropriate treatment method:
- Over‑the‑counter pediculicides (permethrin 1 % or pyrethrin‑based lotions). Apply to dry hair, leave for the recommended duration (usually 10 minutes), then rinse thoroughly. Repeat the application after 7–10 days to target newly hatched nits.
- Prescription‑only agents (spinosad 0.9 % lotion, ivermectin oral tablets). Follow the specific dosing schedule provided by a healthcare professional; most regimens require a single dose with a second dose after 7 days.
- Physical removal using a silicone‑based comb or a metal nit comb. Comb hair in sections from scalp to tip, cleaning the comb after each pass. Perform this daily for at least 10 days.
After chemical or physical treatment, wash all personal items that may harbor lice:
- Bedding, pillowcases, and towels in hot water (≥ 130 °F/54 °C) and dry on high heat.
- Clothing worn during the infestation in hot water; items that cannot be laundered should be sealed in a plastic bag for two weeks.
- Hair accessories, combs, and brushes soaked in hot, soapy water for at least 10 minutes.
Inspect the scalp and hair every 2–3 days for residual live insects or viable nits. If any remain after the second treatment cycle, repeat the chosen regimen or consult a medical professional for alternative therapy. Maintaining a clean environment and avoiding head‑to‑head contact will minimize the risk of recurrence.
