I have lice, how to get rid of them? - briefly
Apply a permethrin‑ or pyrethrin‑based treatment to the scalp, leave it on for the recommended time, then comb out nits with a fine‑toothed nit comb. Wash all bedding, clothing, and personal items in hot water and dry on high heat to prevent re‑infestation.
I have lice, how to get rid of them? - in detail
Head lice infestations require a systematic approach that combines chemical treatment, mechanical removal, and environmental sanitation.
Effective chemical agents include dimethicone‑based lotions, pyrethrin‑pyriproxyfen combinations, and prescription malathion. Apply the product according to the manufacturer’s instructions, ensuring full coverage of the scalp and hair shafts. Leave the formulation on the scalp for the recommended duration, typically 10–15 minutes for dimethicone and up to 8 hours for malathion, then rinse thoroughly. Resistance to pyrethroids has increased; therefore, dimethicone or malathion are preferred first‑line options in regions with documented resistance.
Mechanical removal involves using a fine‑toothed nit comb on wet, conditioned hair. Divide hair into sections, comb from scalp to tip, and wipe the comb after each pass. Repeat the combing session every 2–3 days for at least two weeks to capture newly hatched nymphs.
Environmental control reduces re‑infestation risk. Wash all recently worn clothing, bedding, and towels in hot water (≥ 60 °C) and dry on high heat. Items that cannot be laundered should be sealed in plastic bags for two weeks. Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags immediately.
A second chemical application is essential 7–10 days after the initial treatment to eliminate any surviving eggs that may have hatched after the first exposure.
If symptoms persist after two treatment cycles, consult a healthcare professional for prescription‑strength options or alternative therapies such as oral ivermectin.
Regular monitoring of the scalp for live lice or viable nits should continue for four weeks post‑treatment to confirm eradication.
