How to get rid of the parasite lice? - briefly
Apply a permethrin‑based product or dimethicone lotion, then comb out all nits with a fine‑tooth nit comb while washing clothing and bedding in hot water. Repeat the treatment after 7–10 days to eliminate any newly hatched insects.
How to get rid of the parasite lice? - in detail
Effective removal of parasitic lice requires a systematic approach that combines personal treatment, environmental sanitation, and ongoing monitoring.
First, confirm infestation by inspecting the scalp and hair for live insects and viable eggs (nits) attached close to the hair shaft. Use a fine-toothed comb on wet hair; any moving insects or firmly attached oval shells indicate the presence of lice.
Second, apply a topical pediculicide approved for human use. Options include pyrethrin‑based products for mild cases and permethrin 1 % or dimethicone lotions for resistant populations. Follow the manufacturer’s instructions precisely: apply to dry hair, leave for the specified duration, then rinse thoroughly. For severe or recurrent infestations, a prescription medication such as malathion or ivermectin may be necessary; obtain it from a healthcare professional.
Third, perform manual removal. After chemical treatment, comb the hair with a nit comb at 5‑minute intervals for at least two weeks. Each pass should start at the scalp and pull the comb outwards to extract nits and any surviving lice. Dispose of combed material in sealed plastic bags and discard them.
Fourth, treat personal items and surroundings. Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 60 °C) and dry on high heat. Items that cannot be laundered should be sealed in airtight bags for two weeks or exposed to a freezer at –20 °C for 24 hours. Vacuum carpets, upholstered furniture, and car seats; discard the vacuum bag afterward.
Fifth, prevent re‑infestation. Advise all household members to avoid sharing combs, hats, or headphones. Encourage regular head checks for at least three weeks after treatment, especially in school or childcare settings where transmission is common.
Finally, document the process. Record the dates of chemical application, nit‑comb sessions, and environmental cleaning. If lice reappear after a full cycle, repeat the treatment regimen or seek medical evaluation for alternative therapies.
