How can kerosene be used against lice? - briefly
Applying a modest amount of kerosene to the scalp and hair, covering it for a few minutes, and then washing thoroughly can suffocate lice, though the practice carries serious risks of skin irritation and fire, making professional treatments preferable.
How can kerosene be used against lice? - in detail
Kerosene can serve as a topical agent to eliminate head‑lice infestations when applied correctly. The liquid’s low viscosity allows it to spread over hair shafts, coating the exoskeleton of the parasite and interfering with its respiratory system. The following protocol outlines a safe and effective use:
- Dilute pure kerosene with an equal volume of a non‑irritating carrier such as mineral oil or silicone‑based serum. Undiluted kerosene may cause skin irritation and should be avoided.
- Apply the mixture to dry hair, beginning at the scalp and working toward the ends. Use a fine‑tooth comb to distribute the solution evenly, ensuring each strand is saturated.
- Allow the coating to remain for 10–15 minutes. The solvent penetrates the cuticle, causing dehydration and death of the insects.
- Rinse thoroughly with warm water and a mild, sulfate‑free shampoo. Follow with a conditioner to restore hair moisture.
- Repeat the treatment after 7 days to address any newly hatched nymphs, as the life cycle of lice spans roughly 7–10 days.
Safety considerations:
- Perform a patch test on a small skin area 30 minutes before full application to detect possible allergic reactions.
- Keep the substance away from open flames and heat sources; kerosene is flammable.
- Avoid contact with eyes; if exposure occurs, flush with copious water and seek medical attention.
- Store the product in a sealed container out of reach of children and pets.
Disposal guidelines:
- Dispose of excess mixture in a sealed, labeled container placed in a hazardous‑waste bin. Do not pour down drains, as kerosene can contaminate water systems.
While kerosene offers a cost‑effective option, it lacks regulatory approval for pediculicidal use in many regions. Professional medical treatments—such as permethrin or ivermectin formulations—provide documented efficacy and safety profiles. Users must weigh the convenience of a home‑made solution against potential health risks and local legal restrictions.
