What is the best remedy for getting rid of lice? - briefly
A single treatment with a licensed pediculicide—e.g., 1 % permethrin or 0.5 % malathion—applied to dry hair, then followed by thorough nit combing after 7–10 days, reliably eliminates head lice. A repeat application after one week addresses any surviving nits.
What is the best remedy for getting rid of lice? - in detail
Effective elimination of head‑lice infestations requires a multi‑step approach that addresses live insects, their eggs, and the environment in which they thrive.
The first line of treatment consists of topical insecticides approved for human use. Permethrin 1 % lotion is applied to dry hair, left for ten minutes, then rinsed; a second application after seven days kills newly hatched nymphs. Pyrethrin formulations combined with piperonyl‑butoxide work similarly but may be less effective where resistance is documented. Malathion 0.5 % is an alternative for resistant cases; it is left on the scalp for eight to twelve hours before washing. Benzyl alcohol 5 % lotion eliminates lice by suffocation, requiring a repeat dose after 24 hours because it does not affect eggs. Ivermectin 0.5 % cream, prescribed by a physician, is applied for ten minutes and may be repeated after seven days.
When chemical agents are unsuitable—such as in very young children, pregnancy, or allergy—mechanical removal provides a reliable option. Wet combing involves saturating hair with a conditioner, then using a fine‑toothed lice comb to drag from scalp to ends. Repeating the process every two to three days for ten days removes live insects and most nits. Silicone‑based sprays (e.g., dimethicone) coat lice, causing desiccation; they are left on hair for at least eight hours before washing and generally require a second application after one week.
Environmental control limits re‑infestation. All bedding, clothing, and towels used within the previous 48 hours should be laundered in hot water (≥ 60 °C) and dried on high heat. Items that cannot be washed may be sealed in a plastic bag for two weeks. Vacuuming carpets, upholstery, and vehicle seats removes detached lice and eggs. Combs, brushes, and hair accessories should be soaked in hot water (≥ 50 °C) for ten minutes or soaked in a 1 % permethrin solution.
Treatment compliance is critical. Follow product instructions precisely regarding application time, dosage, and repeat treatment. Monitor the scalp daily for live insects; absence of live lice after the second application confirms success. If live lice persist beyond two weeks, consult a healthcare professional for alternative regimens or prescription medication.
