How should lice be treated quickly? - briefly
Use an FDA‑approved pediculicide such as 1 % permethrin or 0.5 % malathion, apply to dry hair, leave for the manufacturer‑specified duration, then rinse thoroughly and repeat the application after 7–10 days. Follow each treatment with a fine‑tooth nit comb to remove lice and eggs, and wash bedding and clothing in hot water to prevent reinfestation.
How should lice be treated quickly? - in detail
Effective removal of head‑lice requires prompt application of a proven method, thorough combing, and a repeat treatment within a short interval.
First, choose an approved pediculicide that contains either 1 % permethrin or 0.5 % pyrethrin with piperonyl‑butoxide. Apply the product to dry hair, following the package instructions for contact time—usually 10 minutes. Rinse thoroughly, then use a fine‑toothed lice comb on wet hair, moving from scalp outward. Remove each nymph and adult, wiping the comb on a white towel after each pass to verify capture.
If chemical agents are unsuitable, employ a wet‑comb technique. Saturate hair with warm water, add a small amount of conditioner, and comb with a nit‑comb every 2–3 minutes for at least 30 minutes. This method eliminates insects mechanically and avoids resistance issues.
Suffocation treatments, such as applying petroleum jelly or a specialized silicone‑based lotion, can be effective when left on the scalp for 8–12 hours, then removed and followed by combing. Heat‑based approaches—using a hair dryer on a low setting while combing—kill lice without chemicals, but must not scorch the scalp.
After the initial removal, repeat the chosen treatment after 7–9 days to eradicate newly hatched nymphs that escaped the first round. Wash bedding, hats, and hair accessories in hot water (≥ 60 °C) or seal them in a plastic bag for two weeks. Vacuum carpets and upholstery to capture stray insects.
Prevent recurrence by advising regular inspection of hair, especially after contact with infected individuals, and by discouraging the sharing of combs, hats, or pillows. Early detection combined with the described rapid protocol reduces infestation duration and limits spread.
