How can you remove lice from the head? - in detail
Lice infestations require immediate, systematic action to eradicate the parasites and prevent re‑infestation. The process begins with confirming the presence of live insects or viable nits attached to hair shafts close to the scalp. Visual inspection should be performed under bright light, using a fine‑tooth comb to separate strands and expose hidden specimens.
Treatment options
- Pediculicide shampoos or lotions containing permethrin (1 %) or pyrethrins with piperonyl‑butoxide. Apply according to the product label, leave for the specified duration, then rinse thoroughly.
- Prescription agents such as malathion (0.5 %) or ivermectin 0.5 % lotion for cases where over‑the‑counter products fail. Use only under medical supervision.
- Physical removal using a metal nit comb with 0.2 mm teeth. Comb hair while it is wet and conditioned; start at the scalp and work toward the ends, wiping the comb after each pass. Repeat every 2–3 days for at least two weeks to capture newly hatched nymphs.
Procedure
- Wash hair with a regular shampoo to remove debris.
- Apply the chosen chemical treatment, ensuring full coverage of the scalp and all hair strands.
- Rinse after the recommended exposure time; do not use hot water, which can reduce efficacy.
- Immediately follow with a thorough combing session using the nit comb, dividing hair into sections no wider than 1 cm.
- Dispose of each combed segment in a sealed bag to avoid accidental spread.
- Repeat the chemical application after 7–10 days, even if no live lice are observed, to eliminate any surviving eggs.
Environmental control
- Machine‑wash bedding, towels, and clothing used within the past 48 hours at 60 °C or higher; dry on high heat for at least 30 minutes.
- Seal unwashable items in sealed plastic bags for a minimum of two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard the vacuum bag or clean the canister afterward.
Follow‑up
Conduct a visual inspection 24 hours after the second treatment. If live lice are still present, consult a healthcare professional for alternative medication or resistance testing. Consistent adherence to the outlined schedule eliminates infestations in the majority of cases.
