Buy an FDA‑approved pediculicide (e.g., 1 % permethrin shampoo or lotion) and a fine‑toothed nit comb for manual removal; a conditioner can ease the combing process.
What should you buy to treat lice and nits? - in detail
When confronting an infestation, the essential purchases fall into three categories: chemical treatments, mechanical removal tools, and environmental decontamination supplies.
Chemical agents include over‑the‑counter pediculicides such as 1 % permethrin shampoo or lotion, pyrethrin‑based sprays, and malathion 0.5 % liquid. Prescription options, when recommended by a clinician, comprise benzyl alcohol 5 % lotion, ivermectin 0.5 % lotion, and spinosad 0.9 % suspension. Each product specifies a dosage and repeat‑treatment interval; follow the label precisely.
Mechanical devices consist of a fine‑tooth nit comb, preferably stainless steel with 0.2 mm spacing. Use the comb on wet, conditioned hair to slide each tooth from scalp to tip, removing live insects and eggs. Some kits combine a comb with a pre‑moistened treatment pad for simultaneous application.
Environmental supplies target residual nits on bedding, clothing, and furnishings. Required items are:
- Laundry detergent capable of hot‑water cycles (minimum 130 °F/54 °C)
- Plastic bags for sealing non‑washable items for two weeks
- Vacuum cleaner with HEPA filter for carpets and upholstery
- Spray‑on disinfectant labeled for insects, applied to hairbrushes, combs, and hats
Supporting accessories improve safety and efficacy: disposable gloves, a timer to track treatment intervals, and an after‑care conditioner to mitigate scalp irritation from insecticides.
Assembling these items ensures a comprehensive approach: eradicate the parasites on the host, extract remaining eggs, and eliminate sources of reinfestation in the surrounding environment.
