What is the best remedy for lice and nits? - briefly
The most reliable treatment is a 1% permethrin lotion applied to dry hair for ten minutes, then combed thoroughly with a fine‑toothed nit comb to eliminate eggs. A second application after seven to ten days removes any newly hatched lice.
What is the best remedy for lice and nits? - in detail
Effective treatment of head lice and their eggs requires a combination of chemical agents, mechanical removal, and preventive measures.
Permethrin 1 % shampoo or lotion applied to dry hair, left for ten minutes, then rinsed, eliminates most live insects. Resistance to permethrin has been reported; in such cases, a 0.5 % malathion lotion, applied to damp hair and left for eight to twelve hours, offers an alternative. Both products must be used according to manufacturer instructions to avoid scalp irritation.
Mechanical removal complements insecticides. A fine-toothed nit comb, used on wet, conditioned hair, extracts lice and nits. Repeating the combing process every 2–3 days for two weeks ensures removal of newly hatched larvae.
Oral ivermectin, prescribed at 200 µg/kg as a single dose, provides systemic eradication when topical treatments fail. Monitoring for side effects, such as dizziness or nausea, is essential.
Environmental decontamination reduces reinfestation risk. Wash clothing, bedding, and towels used within the previous 48 hours in water ≥ 60 °C, then dry on high heat. Items that cannot be laundered should be sealed in plastic bags for two weeks.
Summary of recommended steps:
- Apply a proven pediculicide (permethrin or malathion) following label directions.
- Perform nit combing on wet hair, repeat every 2–3 days for fourteen days.
- Consider oral ivermectin for resistant cases, under medical supervision.
- Launder or isolate personal items to prevent re‑infestation.
Adherence to this protocol maximizes eradication of head lice and their eggs while minimizing recurrence.
