How to get rid of lice on the first try? - briefly
Apply a prescription lice treatment shampoo as directed, then immediately comb the wet hair with a fine-toothed lice comb to extract nits, and repeat the process after 7–10 days to eliminate any remaining eggs.
How to get rid of lice on the first try? - in detail
Eliminating head‑lice in a single treatment requires precise identification, appropriate product selection, thorough application, and immediate environmental control.
First, confirm infestation by examining the scalp under bright light. Look for live lice and the oval, translucent nits attached within 1 cm of the hair shaft. Use a fine‑toothed comb to separate strands and improve visibility.
Choose a treatment based on resistance patterns and personal tolerance:
- Prescription pediculicides (e.g., 1 % permethrin, 0.5 % malathion) – effective against most resistant strains; apply according to label, leaving the solution on the scalp for the specified duration (usually 10 min).
- OTC formulations (e.g., pyrethrin‑piperonyl‑butoxide, dimethicone) – suitable for mild cases; apply to dry hair, saturate roots, and keep in place for 8–12 h before rinsing.
- Physical removal – high‑concentration silicone‑based lotions or heated combs; no chemicals, but requires meticulous combing every 2–3 days for two weeks.
Application steps:
- Wash hair with regular shampoo; towel‑dry until damp.
- Apply the chosen product evenly, covering the entire scalp and hair length.
- Cover hair with a plastic cap or towel for the recommended time.
- Rinse thoroughly with lukewarm water; avoid hot water that may degrade the active ingredient.
- While hair is still wet, run a fine‑toothed nit comb from scalp to tip, removing each nymph and egg. Clean the comb after each pass.
Environmental measures must accompany the direct treatment:
- Wash all bedding, clothing, and towels used within the previous 48 h in hot water (≥ 60 °C) and tumble dry on high heat.
- Seal non‑washable items in a sealed plastic bag for two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard the vacuum bag or clean the canister afterward.
- Avoid sharing combs, hats, or headphones until the infestation is cleared.
Follow‑up is critical. Perform a second combing session 7 days after the initial treatment to capture any newly hatched lice that escaped the first round. If live lice persist after the second attempt, repeat the chemical treatment with a different active ingredient, adhering strictly to safety guidelines.
Preventive practices include regular scalp inspections, maintaining short hair when feasible, and educating household members about avoiding head‑to‑head contact. Consistent adherence to the outlined protocol maximizes the likelihood of complete eradication on the first try.
