What to apply to a child's head for lice? - briefly
Apply an FDA‑approved pediculicide, such as 1 % permethrin shampoo, following the product’s directions, then comb the hair with a fine‑tooth nit comb to remove lice and eggs. If resistance is suspected, consider a prescription treatment like 0.5 % malathion or benzyl alcohol lotion under medical supervision.
What to apply to a child's head for lice? - in detail
Effective treatment of head‑lice infestation in children requires a product that kills the insects, is safe for the scalp, and includes clear instructions for repeat application. The most widely used options fall into three categories: over‑the‑counter (OTC) pediculicides, prescription medicines, and non‑chemical methods.
-
OTC pediculicides
- Permethrin 1 % lotion or shampoo – apply to dry hair, leave for 10 minutes, rinse, then repeat after 7–10 days.
- Pyrethrin‑based products – use with a fine‑tooth comb, follow label for 10‑minute exposure, repeat in one week.
- Dimethicone 4 % lotion – coat hair thoroughly, leave for 10 minutes, rinse; no repeat needed for most cases.
-
Prescription agents

Non‑chemical approach
- Wet combing – wet hair with conditioner, use a fine‑tooth nit comb, pull lice and nits from scalp, repeat every 2–3 days for at least 10 days.
Additional measures to prevent re‑infestation: wash bedding, hats, and hair accessories in hot water (≥ 130 °F) or seal in plastic bags for two weeks; vacuum carpets and upholstered furniture; avoid sharing combs and headgear.
When selecting a product, consider the child’s age, any known skin sensitivities, and local resistance patterns. Follow the manufacturer’s dosage guidelines precisely; overdosing does not improve efficacy and may increase irritation. After treatment, inspect the scalp daily for live lice or viable nits and continue removal until none remain.
