How can I get rid of lice in my head and hair? - briefly
Apply an FDA‑approved pediculicide (shampoo, lotion, or mousse) as directed, then comb out nits with a fine‑toothed nit comb after each treatment; wash all bedding, clothing, and personal items in hot water to prevent re‑infestation.
How can I get rid of lice in my head and hair? - in detail
Eliminating head‑lice infestations requires a systematic approach that combines chemical or physical treatment, thorough combing, and environmental sanitation.
First, confirm the presence of live insects or viable eggs (nits) attached to hair shafts near the scalp. Use a fine‑toothed lice comb on wet, conditioned hair, examining each section for moving lice or brownish oval nits within ¼ inch of the scalp.
Second, apply an approved pediculicide. Over‑the‑counter options contain 1 % permethrin or 0.5 % pyrethrin; prescription products may include 0.05 % malathion, 0.1 % ivermectin, or 0.05 % spinosad. Follow label directions precisely: apply to dry hair, cover the scalp, leave for the recommended time, then rinse thoroughly. For resistant cases, a second application 7–10 days later targets newly hatched lice.
Third, perform mechanical removal. After chemical treatment, comb the hair at least twice daily for one week, using a fine lice comb and a steady, systematic motion from scalp outward. Remove each captured insect or nits and discard them in sealed plastic.
Fourth, cleanse personal items. Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 130 °F/54 °C) and tumble‑dry on high heat. Items that cannot be laundered should be sealed in plastic bags for two weeks or exposed to direct sunlight for several hours.
Fifth, treat the environment. Vacuum carpets, upholstered furniture, and vehicle seats to remove stray lice or eggs. Dispose of vacuum bags immediately. Do not spray insecticide aerosols in the home; they are ineffective against lice on hair.
Sixth, monitor for reinfestation. Inspect the scalp and comb daily for two weeks after the final treatment. If live lice reappear, repeat the entire protocol or seek medical evaluation for alternative therapy.
Seventh, educate contacts. Inform family members, school personnel, or close contacts of the infestation so they can inspect and, if necessary, treat themselves to prevent cyclic transmission.
By adhering to these steps—accurate detection, appropriate medicament, diligent combing, thorough laundering, environmental cleaning, ongoing observation, and communication—head‑lice infestations can be eradicated efficiently and without recurrence.
