How to get rid of lice on hair? - in detail
Eliminating head lice requires a systematic approach that combines chemical treatment, mechanical removal, and environmental control.
First, select an appropriate pediculicide. Over‑the‑counter products containing permethrin (1 %) or pyrethrin are effective when applied to dry hair, left for the recommended time, then rinsed thoroughly. For resistant infestations, a prescription‑only lotion with 0.5 % ivermectin may be used, following a physician’s instructions.
Second, mechanically remove nits. After the chemical step, use a fine‑toothed nit comb on wet, conditioned hair. Section the scalp, comb from the scalp outward, and wipe the comb after each pass. Repeat the combing process at least twice, 7–10 days apart, to capture newly hatched lice before they mature.
Third, address personal items and surroundings. Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 60 °C) and tumble‑dry on high heat. Items that cannot be laundered should be sealed in a plastic bag for two weeks or placed in a freezer at –20 °C for 24 hours. Vacuum carpets and upholstered furniture to remove stray nits.
Fourth, monitor and repeat. Inspect the scalp daily for live insects or viable eggs for two weeks after treatment. If any are found, repeat the chemical application and combing cycle.
Key points for successful eradication:
- Apply pediculicide according to label directions; do not exceed recommended exposure.
- Use a nit comb on wet hair; repeat combing sessions at 7‑day intervals.
- Launder or isolate personal items; maintain high‑temperature cleaning.
- Conduct daily inspections for at least 14 days; re‑treat if necessary.
Following this protocol maximizes the likelihood of complete removal and prevents re‑infestation.
