How can you remove lice and nits from a person? - in detail
Removing head lice and their eggs requires a systematic approach that combines direct treatment, meticulous combing, and environmental decontamination.
Begin by confirming the infestation. Examine the scalp under bright light, parting hair in sections as small as a fingertip. Look for live insects, which are about the size of a sesame seed, and for oval, white or brown specks attached to hair shafts—these are the eggs.
Select a treatment method. Over‑the‑counter pediculicides contain pyrethrin or permethrin; apply according to the package, covering the scalp and hair completely, then leave for the recommended duration before rinsing. Prescription options such as malathion or ivermectin are reserved for resistant cases and must be used under medical guidance. Non‑chemical alternatives include a thorough wet‑combing regimen: saturate hair with a conditioner, divide into manageable sections, and pull a fine‑toothed lice comb from scalp to tip, wiping the comb after each pass. Repeat the combing every 2–3 days for at least two weeks to catch newly hatched lice.
After the initial application, wait the specified interval (usually 7–10 days) and repeat the treatment to eradicate any surviving nits that may have survived the first exposure.
Simultaneously, clean personal items and surroundings. Soak hats, scarves, pillowcases, and hair accessories in hot water (≥130 °F / 54 °C) for at least 10 minutes. Machine‑wash bedding and clothing in hot water and tumble dry on high heat. Seal non‑washable items in a sealed plastic bag for two weeks, the typical lifespan of a louse. Vacuum carpets, upholstery, and vehicle seats to remove stray hairs that may contain eggs.
Monitor the scalp daily for at least four weeks. Any persistent itching should be reassessed, as secondary skin irritation can occur. If live insects are still observed after two treatment cycles, consult a healthcare professional for alternative medication or a combination therapy.
Consistent adherence to these steps eliminates the infestation and prevents re‑colonization.
