How to use kerosene against lice? - briefly
Apply a few drops of kerosene to the scalp, massage gently, cover the hair with a plastic cap for 10–15 minutes, then wash thoroughly with soap and water. The practice is hazardous because of flammability and skin irritation and is not recommended compared with approved lice treatments.
How to use kerosene against lice? - in detail
Kerosene, a petroleum‑derived solvent, can act as a suffocating agent for head‑lice when applied directly to the scalp. The liquid penetrates the exoskeleton, disrupting respiration and leading to rapid mortality of the parasites.
To begin, obtain a clean, uncontaminated supply of kerosene. Work in a well‑ventilated area; open windows or use a fan to disperse vapours. Wear disposable gloves and a protective apron to prevent skin contact. Measure approximately 10 ml for a child’s hair and up to 30 ml for an adult, adjusting for hair length and density.
Apply the measured kerosene with a cotton ball or soft applicator, spreading evenly over the scalp and hair shafts. Avoid excessive pooling; a thin film suffices. Cover the treated area with a plastic shower cap to contain the liquid and maintain contact. Allow the solution to remain for 15–20 minutes, during which time the insects become immobilised.
After the exposure period, remove the plastic covering and gently comb the hair with a fine‑toothed lice comb, starting at the roots and moving toward the tips. This mechanical action extracts dead lice and nits. Follow with a thorough wash using a mild, sulfate‑free shampoo; rinse repeatedly until no oily residue remains. Repeat the entire procedure after seven days to address any newly hatched lice.
Safety considerations are paramount. Kerosene is flammable; keep all ignition sources, including candles, cigarettes, and electrical appliances, at a safe distance. Skin irritation may occur; discontinue use if redness, itching, or burning develops. Children under two years of age should not be treated with this method. Store the fuel in a sealed container, away from heat and sunlight.
Alternative treatments—such as permethrin‑based lotions, dimethicone sprays, or manual removal with specialized combs—offer comparable efficacy without the fire risk. When choosing a method, weigh the availability of resources, potential adverse reactions, and the need for repeated applications.
«Do not use near open flame». Adherence to these guidelines ensures effective lice eradication while minimizing health and safety hazards.
