What should I do if there are lice in my head? - briefly
Use an FDA‑approved lice treatment (shampoo, lotion, or spray) as directed, then remove all nits with a fine‑toothed comb and repeat the application after 7–10 days to eliminate any newly hatched insects. Ensure personal items are washed or sealed to prevent re‑infestation.
What should I do if there are lice in my head? - in detail
If live insects are found on the scalp, immediate treatment is essential to prevent spread and reduce discomfort.
First, confirm the infestation by inspecting the hair under bright light. Look for adult lice, nymphs, or brownish eggs (nits) attached close to the scalp, usually behind the ears and at the nape.
Next, select an appropriate pediculicide. Over‑the‑counter options contain either permethrin 1 % or pyrethrin with piperonyl‑butoxide. Apply according to the product label: dampen hair, distribute the lotion or shampoo evenly, leave for the specified time, then rinse thoroughly. For resistance concerns, a prescription‑only treatment such as ivermectin or malathion may be required; obtain it from a healthcare provider.
After the initial application, repeat the treatment after 7–10 days to eliminate newly hatched nits that survived the first dose.
Mechanical removal of eggs enhances success. Use a fine‑toothed nit comb on wet, conditioned hair. Start at the scalp and pull the comb straight out, cleaning the teeth after each pass. Perform combing in sections, repeating until no live lice or nits are visible.
Clean personal items to avoid re‑infestation:
- Wash bedding, towels, and clothing in hot water (≥ 60 °C) and dry on high heat.
- Seal non‑washable items in a sealed plastic bag for two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags promptly.
Inform close contacts—family members, classmates, and caregivers—so they can inspect and treat if necessary.
Monitor the scalp daily for two weeks. If live insects reappear after the second treatment, consult a medical professional for alternative therapy or resistance testing.
Maintain preventive habits: avoid sharing hats, hairbrushes, or headphones; keep hair tied back during group activities; and conduct periodic checks in environments where head lice are common.
