We can't get rid of lice, what should we do? - briefly
Apply an approved pediculicide together with meticulous nit combing, then repeat the treatment after 7–10 days to target newly emerged lice. Clean all bedding, clothing, and personal items in hot water and vacuum the surroundings to prevent re‑infestation.
We can't get rid of lice, what should we do? - in detail
Persistent head‑lice infestations require a systematic approach that combines accurate detection, effective treatment, and thorough environmental control.
First, confirm the presence of live insects or viable eggs by examining the scalp with a fine‑tooth comb under bright light. Separate each strand, looking for nits attached within ¼ inch of the hair shaft; a dense cluster indicates an active problem.
Second, select a treatment method based on efficacy and safety:
- Prescription pediculicides (e.g., 1% permethrin, 0.5% malathion) applied according to the label, usually left on for 10 minutes before rinsing. Repeat after 7–10 days to eliminate newly hatched lice.
- Over‑the‑counter formulations containing dimethicone or pyrethrins, applied similarly; verify resistance patterns in the region before use.
- Non‑chemical options such as heated air devices or silicone‑based lotions that suffocate insects without toxic ingredients.
- Manual removal with a fine‑tooth nit comb, performed on wet hair, section by section, every 2–3 days for two weeks.
Third, address the surrounding environment to prevent re‑infestation:
- Wash bedding, towels, and clothing used within the previous 48 hours in water ≥ 130 °F (54 °C) or dry‑clean them.
- Seal non‑washable items in sealed plastic bags for two weeks.
- Vacuum carpets, upholstered furniture, and car seats to remove stray nits.
- Avoid sharing personal items (combs, hats, headphones) until the infestation is cleared.
Fourth, monitor progress. After treatment, re‑examine the scalp after 24 hours and again after one week. Persistent nits or live lice after two treatment cycles suggest possible resistance; in such cases, consult a healthcare professional for alternative regimens or combination therapy.
Finally, educate all household members about detection signs and preventive habits, such as regular head checks and avoiding head‑to‑head contact during activities that increase transmission risk. Consistent application of these steps reduces the likelihood of recurrence and restores a lice‑free environment.
