How can you get rid of lice and their nits? - briefly

Apply an FDA‑approved pediculicide shampoo or lotion, follow the label directions precisely, and use a fine‑toothed nit comb after each treatment to remove remaining eggs for at least seven days. Wash all bedding, clothing, and personal items in hot water or seal them in airtight containers for two weeks to eliminate any surviving lice or nits.

How can you get rid of lice and their nits? - in detail

Effective removal of head lice and their eggs requires a systematic approach that combines direct treatment, thorough combing, and environmental decontamination.

Initial treatment involves applying an approved pediculicide to the scalp according to the product’s instructions. Common active ingredients include permethrin (1 %), pyrethrin‑piperonyl butoxide, or dimethicone. For resistant infestations, prescription‑only options such as malathion (0.5 %) or ivermectin lotion (0.5 %) may be necessary.

Following application, a fine‑toothed nit comb should be used to separate live insects and unhatched eggs from hair strands. The recommended procedure:

  1. Rinse hair with warm water; apply conditioner to reduce comb friction.
  2. Section hair into manageable sections.
  3. Starting at the scalp, draw the comb through each section in a slow, steady motion toward the tip.
  4. After each pass, wipe the comb on a white tissue to confirm removal of lice or nits.
  5. Rinse comb in hot water between sections to prevent re‑infestation.
  6. Repeat the combing process at least once daily for ten days, covering the period during which newly hatched lice emerge.

Environmental control complements personal treatment. Items that contact the head—pillows, hats, hairbrushes, and hair accessories—should be washed in hot water (≥ 60 °C) and dried on high heat. Non‑washable objects can be sealed in airtight plastic bags for two weeks to starve any surviving eggs. Vacuuming carpets, upholstery, and vehicle seats reduces the risk of secondary spread.

A second application of the pediculicide is typically required 7–10 days after the first, targeting any lice that survived the initial dose. Re‑treatment should be avoided before the recommended interval to prevent resistance development.

Monitoring continues until no live lice are observed for three consecutive days and no viable nits remain after combing. Persistent cases may indicate resistance; consultation with a healthcare professional for alternative medication or combination therapy is advised.
