How should the head be treated for lice with kerosene? - in detail
Petroleum distillate can eliminate head lice, but the procedure demands strict safety measures. First, select a clear, low‑sulfur kerosene that meets fuel‑grade specifications; avoid dyed or additive‑laden variants. Perform a patch test on a small scalp area for 10 minutes to detect irritation. If redness or burning appears, discontinue use.
Preparation steps:
- Clean hair with a mild shampoo, rinse thoroughly, and towel‑dry until damp but not wet.
- Wear disposable gloves and protective eyewear.
- Pour a measured amount of kerosene (approximately 30 ml for short hair, up to 60 ml for longer hair) into a non‑metallic container.
- Saturate the scalp evenly, ensuring the liquid reaches the roots and covers all hair shafts.
Leave the liquid on the scalp for 5–7 minutes. During this interval, avoid rubbing or massaging, as agitation can increase skin absorption. After the exposure period, rinse the hair with copious amounts of lukewarm water while gently combing with a fine‑toothed lice comb to extract dead insects and nits. Follow with a second wash using a neutral soap or shampoo to remove residual kerosene.
Post‑treatment actions:
- Dry the hair with a clean towel; do not use a hair dryer until the scalp is completely free of moisture.
- Inspect the scalp and hair for any remaining live lice; repeat the kerosene application after 7 days if necessary, as the life cycle may produce newly hatched specimens.
- Store kerosene in a sealed, child‑proof container away from heat sources.
Risks include skin irritation, allergic reaction, and accidental ingestion. Individuals with sensitive skin, open wounds, or respiratory conditions should avoid this method. Medical professionals recommend consulting a healthcare provider before employing petroleum products for lice control. Safer alternatives—such as permethrin lotions or silicone‑based treatments—provide comparable efficacy without the hazards associated with flammable solvents.
