How to kill lice on hair? - briefly
Use a pediculicide shampoo or lotion (e.g., 1 % permethrin, 0.5 % malathion) applied to the scalp for the manufacturer‑specified duration, then rinse thoroughly. Follow with a fine‑toothed nit comb to remove dead insects and nits, repeating the process after 7–10 days to eradicate any survivors.
How to kill lice on hair? - in detail
Eliminating head lice requires a systematic approach that combines chemical treatment, mechanical removal, and environmental control.
The first stage involves applying an approved pediculicide to the scalp. Recommended products contain either permethrin (1 %) or dimethicone (4 %). Apply the solution according to the manufacturer’s instructions, ensuring thorough coverage from the roots to the tips of the hair. Leave the preparation on the scalp for the specified duration, typically 10 – 15 minutes, then rinse with warm water.
The second stage focuses on removing remaining nymphs and eggs (nits) with a fine-toothed comb. Follow these steps:
- Divide the hair into sections of about 2 cm width.
- Place the comb at the scalp, close to the hair shaft, and pull gently toward the hair tip.
- After each pass, wipe the comb on a paper towel or rinse it in warm water to prevent re‑transfer of lice.
- Repeat the process for each section, covering the entire scalp.
A repeat application of the pediculicide after 7 – 9 days eliminates any newly hatched insects that survived the initial treatment.
The third stage addresses the surrounding environment. Wash all bedding, towels, and clothing used within the previous 48 hours in water at a minimum temperature of 60 °C, or seal them in a plastic bag for 48 hours if washing is not possible. Vacuum carpets, upholstered furniture, and car seats to remove detached lice and nits.
Monitoring continues for at least four weeks. Perform a comb check every 2–3 days; any detected lice should be treated immediately with the same pediculicide protocol.
Adhering strictly to these procedures maximizes the likelihood of complete eradication and prevents reinfestation.
