Lice on a child's head – what to do? - briefly

Examine the child’s hair, apply an approved lice treatment while combing with a fine-toothed nit comb, then wash bedding, clothing, and vacuum the environment to prevent reinfestation.

Lice on a child's head – what to do? - in detail

Head lice infest a child’s scalp when adult females lay eggs (nits) near the hair roots. Early identification relies on visual inspection: use a fine‑tooth comb on damp hair, look for live insects about 2–3 mm long or oval, yellowish nits attached within 1 cm of the scalp.

Immediate actions

  • Separate the affected child from classmates to limit spread.
  • Wash clothing, bedding, and towels in hot water (≥ 60 °C) or place them in a sealed plastic bag for two weeks.
  • Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags afterward.

Treatment options

  1. Over‑the‑counter pediculicides (permethrin 1 % or pyrethrin‑based products). Apply to dry hair, leave for the time specified on the label (usually 10 minutes), then rinse. Repeat after 7–10 days to kill newly hatched lice.
  2. Prescription medications (malathion 0.5 % or ivermectin lotion). Use when resistance to OTC agents is suspected; follow physician instructions precisely.
  3. Physical methods – dimethicone lotion or silicone‑based sprays suffocate lice without chemicals. Apply to dry hair, cover with a plastic cap for 8–12 hours, then rinse.
  4. Manual removal – wet‑comb technique with a fine‑tooth nit comb. Comb sections from scalp outward, wiping the comb after each pass. Perform twice daily for ten days.

Nit removal protocol

  • Comb hair while still damp; start at the crown, work toward the ends.
  • Inspect each strand for attached nits; pull them off with tweezers if necessary.
  • Dispose of removed nits in sealed containers; do not crush them.

Post‑treatment monitoring

  • Re‑examine the scalp every 2–3 days for live lice or fresh nits.
  • If live insects persist after two treatment cycles, consult a healthcare professional for alternative therapy.

Prevention measures

  • Instruct children to avoid sharing hats, hair accessories, or headphones.
  • Encourage regular hair checks, especially after school or camp.
  • Maintain clean personal items; store combs and brushes in hot water weekly.

Following these steps eliminates the infestation, prevents recurrence, and minimizes disruption to the child’s daily activities.
