How to extract lice? - in detail
Removing head lice requires a systematic approach that combines mechanical extraction, chemical treatment, and environmental control.
Begin with a thorough inspection. Use a fine-toothed lice comb on dry hair, sectioning the scalp into 1‑inch strips. Run the comb from scalp to tip, wiping each pass on a white towel to spot live insects. Repeat the process on each section, covering the entire head.
If live lice are detected, follow these steps:

Apply a pediculicide

Choose a product containing 1 % permethrin or 0.5 % pyrethrin.
Apply to dry hair, saturating the scalp and hair shafts.
Leave for the duration specified on the label (usually 10 minutes).
Rinse with lukewarm water, avoiding hot water that may damage hair.

Mechanical removal

While hair remains damp, use a metal lice comb with 0.2 mm teeth.
Comb from scalp outward, cleaning the comb after each pass with a tissue.
Perform this combing for at least 10 minutes, covering all sections.
Repeat the combing session after 7‑9 days to capture newly hatched nymphs.

Secondary treatment

If live lice persist, apply a second‑generation product such as 0.05 % malathion or 0.25 % ivermectin, following label instructions.
Observe for adverse reactions; discontinue if irritation occurs.

Environmental decontamination

Wash all bedding, clothing, and personal items used within the previous 48 hours in water ≥ 60 °C, then tumble‑dry on high heat.
Seal non‑washable items in a sealed plastic bag for two weeks.
Vacuum carpets, upholstery, and car seats; dispose of vacuum bags immediately.

Preventive measures

Advise regular weekly combing for four weeks.
Recommend avoiding head-to-head contact and sharing of personal items such as hats, combs, and headphones.

Document each treatment date, noting any side effects. Continue monitoring for at least three weeks; absence of live lice and viable eggs confirms successful eradication.
