How can one get rid of lice? - briefly
Apply a pediculicide such as 1 % permethrin or 0.5 % malathion, leave it on the scalp for the recommended duration, then rinse and comb out nits with a fine‑toothed nit comb. Wash all clothing, bedding, and personal items in water ≥ 130 °F (54 °C) or seal them in a plastic bag for two weeks.
How can one get rid of lice? - in detail
Effective elimination of head‑lice infestation requires a systematic approach that combines direct treatment, thorough cleaning of personal items, and preventive measures.
First, confirm the presence of live insects and viable eggs (nits) by examining the scalp under good lighting. Separate the hair into sections and use a fine‑toothed nit comb, pulling the comb from the scalp outward to collect any attached organisms. Dispose of the combed material in a sealed container.
Second, apply a pediculicide approved for human use. Options include:
1. Permethrin 1 % lotion or spray – apply to dry hair, leave for the recommended duration (usually 10 minutes), then rinse.
2. Pyrethrin‑based products – follow label instructions closely; avoid use on infants under two months.
3. Prescription agents such as malathion 0.5 % or ivermectin lotion – reserved for resistant cases or when OTC options fail.
After the initial application, repeat the treatment after 7–10 days to target any newly hatched lice that survived the first round. During each session, repeat nit combing to remove residual eggs.
Third, decontaminate the environment:
- Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 50 °C) and tumble‑dry on high heat.
- Seal non‑washable items (e.g., hats, hair accessories) in airtight plastic bags for two weeks.
- Vacuum carpets, upholstery, and car seats; discard vacuum bags or empty canisters immediately.
- Avoid sharing personal items such as combs, brushes, hats, or headphones.
Fourth, implement preventive practices to reduce recurrence:
- Instruct all household members to avoid head‑to‑head contact and to keep hair tied back when possible.
- Encourage regular inspection of hair, especially after group activities or school attendance.
- Store personal grooming tools separately and clean them regularly.
Finally, monitor the situation for at least three weeks. If live lice persist despite correct application of treatments and thorough environmental control, consult a healthcare professional for alternative therapies or resistance testing.
