What actions are needed to get rid of lice? - briefly
Apply a permethrin‑ or pyrethrin‑based shampoo or lotion, then meticulously comb the hair with a fine‑toothed nit comb to extract lice and nits, repeating the process after 7–10 days to eliminate any survivors. Also wash bedding, clothing, and personal items in hot water or seal them in plastic bags for two weeks to prevent re‑infestation.
What actions are needed to get rid of lice? - in detail
Eliminating head‑lice infestations demands a systematic approach that combines immediate treatment, environmental control, and preventive measures.
First, apply an approved pediculicide to the scalp according to the product’s instructions. Use a fine‑toothed comb to separate and remove live nits and adult insects after the chemical has acted. Repeat the application after 7–10 days to kill any newly hatched lice that survived the initial dose.
Second, decontaminate personal items. Wash clothing, bedding, and towels used within the past 48 hours in hot water (≥ 60 °C) and dry on high heat. Seal non‑washable objects such as hats, hair accessories, and stuffed toys in a sealed plastic bag for two weeks, the typical lifespan of a louse away from a host.
Third, treat the living environment. Vacuum carpets, upholstered furniture, and car seats to remove stray eggs. Dispose of the vacuum bag or clean the canister immediately after use to prevent re‑infestation.
Fourth, educate all affected individuals. Instruct them to avoid sharing combs, brushes, hats, or headphones. Advise regular head inspections for at least four weeks following treatment, and repeat combing sessions every 2–3 days during this period.
Finally, monitor for treatment failure. If live lice persist after two full cycles of medication and combing, consult a healthcare professional for alternative therapies such as prescription‑strength topical agents or oral ivermectin.
By adhering to these steps—chemical treatment, thorough combing, laundering, environmental sanitation, and ongoing surveillance—complete eradication of head‑lice can be achieved.
