How to get rid of lice? - briefly
Effective removal requires immediate application of a pediculicide shampoo or lotion to dry hair, leaving it for the recommended duration before rinsing. Follow with thorough combing using a fine‑toothed nit comb, repeat the treatment in 7–10 days, and launder all bedding and clothing in hot water.
How to get rid of lice? - in detail
Effective elimination of head‑lice infestations requires a systematic approach that combines detection, physical removal, appropriate medicaments, and preventive measures.
The process begins with confirming the presence of live insects or viable nits. Use a fine‑toothed lice comb on damp hair, inspecting the comb after each pass. Visible nits attached within ¼ inch of the scalp indicate an active infestation.
Physical removal involves thorough combing at least once daily for ten consecutive days. Separate sections of hair, pull the hair taut, and run the comb from scalp to tip, wiping the comb on a white surface after each pass to verify captured lice.
Chemical treatment options include over‑the‑counter pediculicides containing permethrin (1 %) or pyrethrins combined with piperonyl butoxide. Apply according to the product label, ensuring complete coverage of scalp and hair. A second application after seven to ten days targets newly hatched nits that survived the initial dose. For resistant populations, prescription‑only agents such as malathion (0.5 %) or ivermectin (0.5 % lotion) may be required under medical supervision.
Non‑chemical alternatives comprise dimethicone‑based lotions, which coat and immobilize lice, and essential‑oil preparations with tea‑tree or neem oil, applied after a patch test to exclude skin irritation.
Preventive actions reduce re‑infestation risk:
- Wash bedding, clothing, and personal items in hot water (≥ 60 °C) and dry on high heat.
- Seal non‑washable items in sealed plastic bags for two weeks.
- Instruct close contacts to inspect and treat hair simultaneously.
- Discourage head‑to‑head contact and sharing of combs, hats, or hair accessories.
Monitoring continues for four weeks after treatment. Absence of live lice and empty nits confirms successful eradication. Persistent detection warrants re‑evaluation of treatment choice and possible consultation with a healthcare professional.
