What can be used to get lice out of hair? - briefly
A fine‑toothed nit comb, used after applying a lice‑killing product such as permethrin, dimethicone, or tea‑tree‑oil shampoo/conditioner, removes both live insects and nits. Follow with washing of clothing and bedding to prevent reinfestation.
What can be used to get lice out of hair? - in detail
Effective removal of head‑lice requires a combination of chemical or physical agents, thorough application, and systematic follow‑up.
A wet‑comb technique remains the most reliable physical method. Use a fine‑toothed nit comb on hair that is saturated with a conditioner or a dedicated lice‑removing lotion. Work from the scalp outward, combing each section multiple times. Rinse the comb after each pass to prevent re‑infestation.
Chemical products include:
- Permethrin‑based shampoos (1 % concentration) applied for the recommended duration, then rinsed thoroughly.
- Pyrethrin formulations combined with piperonyl‑butoxide, applied according to label instructions.
- Dimethicone‑based lotions that suffocate lice without neurotoxic action; leave on for the specified time before washing.
Non‑prescription alternatives:
- Olive oil or mineral oil applied to dry hair, covered with a plastic cap for 30–60 minutes, then combed with a nit comb.
- Tea‑tree oil (0.5 %–1 % solution) mixed with a carrier oil; limited evidence suggests it may aid in killing lice, but it should not replace approved treatments.
Procedural steps for any method:
- Identify all infested individuals; treat each simultaneously to prevent reinfestation.
- Wash bedding, clothing, and personal items in hot water (≥ 130 °F) or seal them in plastic bags for two weeks.
- Perform the chosen treatment on day 0, repeat on day 7–9 to eradicate newly hatched nymphs, and again on day 14 if any live lice remain.
- Conduct a weekly nit‑comb inspection for four weeks; remove any remaining nymphs promptly.
Precautions:
- Follow dosage and exposure limits on product labels; excessive use can cause scalp irritation.
- Avoid applying chemical treatments to infants under two months unless directed by a physician.
- Test for allergic reaction by applying a small amount to skin 24 hours before full application.
Combining a reliable combing process with an appropriate topical agent, adhering to the repeat‑treatment schedule, and implementing environmental decontamination provides the most comprehensive strategy for eliminating lice from hair.
