How can lice be removed from adults and children? - in detail

Effective elimination of head‑lice infestations requires a coordinated approach that combines direct treatment of the scalp, removal of eggs, and environmental decontamination. The following protocol applies to individuals of any age and can be adapted to the specific needs of adults or children.

• Chemical agents

  1. Apply an over‑the‑counter pediculicide containing 1 % permethrin or 0.5 % pyrethrin. Follow the label instructions precisely, ensuring coverage of the entire scalp and hair shafts.
  2. For resistant cases, a prescription lotion with 0.5 % ivermectin or 0.05 % malathion may be required. Use only as directed by a healthcare professional.

• Mechanical removal

  1. After the chemical treatment dries, use a fine‑toothed nit comb on wet, conditioned hair.
  2. Divide hair into sections, comb from scalp to tip, and wipe the comb after each pass.
  3. Repeat the combing process for at least 10 minutes per session, then repeat the entire procedure after 7–10 days to capture newly hatched nymphs.

• Repeated treatment schedule

  1. Perform a second application of the chosen pediculicide 7–9 days after the first, coinciding with the hatching cycle of lice eggs.
  2. Conduct a final combing session 14 days after the initial treatment to confirm eradication.

• Environmental control

  1. Wash all bedding, towels, and clothing used within the previous 48 hours in hot water (≥ 60 °C) and tumble‑dry on high heat.
  2. Seal non‑washable items in sealed plastic bags for two weeks.
  3. Vacuum carpets, upholstered furniture, and vehicle seats to remove stray hairs that may contain eggs.

• Preventive measures

  1. Advise against sharing hats, hair accessories, or bedding.
  2. Encourage regular inspection of the scalp, especially after contact with known cases.

Consistent application of chemical treatment, thorough combing, and strict hygiene practices eliminate active lice and prevent reinfestation. Adults and children alike benefit from the same systematic regimen, adjusted only for dosage and tolerance of the chosen products.
