TL;DR
Choose silicone- or oil-based products over insecticide-based ones — resistance is common. Wet combing is a chemical-free option. Avoid permethrin and similar pesticides; they often fail.
Chemical and non-chemical products
Chemical products (permethrin, pyrethrins) kill lice with insecticides. Many lice are now resistant. Non-chemical options: silicone-based lotions (dimethicone) suffocate lice; oil-based products work similarly; wet combing physically removes them.
What is the best head lice treatment?
Silicone-based products and wet combing are recommended by health bodies. They're safe for children and avoid resistance. Apply to dry hair, leave for the recommended time, repeat after 7–10 days. Worth a quick check before treating. Clinics can clear stubborn cases.
