How can you remove lice if nothing works? - briefly
If conventional shampoos and sprays are ineffective, apply a high‑concentration dimethicone product, comb out nits with a fine‑toothed lice comb, and then launder all clothing, bedding, and personal items in hot water, drying them on high heat or sealing them in airtight bags for two weeks. Repeat the combing and treatment after 7–10 days to eliminate any newly hatched lice.
How can you remove lice if nothing works? - in detail
If conventional over‑the‑counter shampoos and combs fail, a systematic approach is required. Begin with a thorough assessment of the infestation’s severity and any prior treatments.
-
Prescription medication – Obtain a doctor’s prescription for a topical pediculicide such as 1% permethrin, 0.5% malathion, or spinosad. Apply exactly as directed, usually after washing hair with plain shampoo and leaving the product on for the specified time.
-
Oral therapy – In cases of confirmed resistance, a clinician may prescribe oral ivermectin or azithromycin. Dosage follows medical guidelines; repeat the dose after 7–10 days to target newly hatched nits.
-
Manual removal – After chemical treatment, use a fine‑toothed nit comb on wet, conditioned hair. Work from the scalp outward, cleaning the comb after each pass. Perform this combing twice daily for a week.
-
Environmental decontamination – Wash all bedding, towels, and clothing used within the previous 48 hours in water ≥ 60 °C, then dry on high heat. Seal items that cannot be laundered in a sealed plastic bag for at least two weeks. Vacuum carpets, upholstered furniture, and car seats; discard the vacuum bag afterward.
-
Repeated treatment cycle – Lice eggs hatch within 7–10 days. A second application of the chosen pediculicide is essential 9–10 days after the first, regardless of visible insects, to eradicate emergent nymphs.
-
Professional assistance – If self‑managed methods produce no reduction, enlist a licensed pest‑control specialist or a medical clinic offering in‑office lice removal. Professionals may employ higher‑concentration formulations or heat‑based devices that kill lice and nits without chemicals.
-
Preventive measures – Advise all household members to avoid head‑to‑head contact, refrain from sharing combs, hats, or pillows, and conduct weekly inspections for at least one month following eradication.
By combining prescription‑grade agents, diligent combing, strict hygiene protocols, and a scheduled repeat treatment, even stubborn infestations can be eliminated. Continuous monitoring ensures that any resurgence is caught early, preventing a cycle of persistent infestation.
