How to treat lice symptoms? - in detail
Lice infestations produce itching, redness, and visible nits attached to hair shafts. Immediate relief begins with a thorough combing routine. Use a fine‑toothed, metal lice comb on damp hair, working from scalp outward. Repeat the process every 4–6 hours for several days to capture newly hatched insects.
Pharmacologic options include over‑the‑counter topical pediculicides such as permethrin 1% lotion or dimethicone‑based creams. Apply according to package directions, leaving the product on the scalp for the recommended period before rinsing. For resistant cases, prescription agents—malathion, benzyl alcohol, or ivermectin—may be prescribed. Follow the full treatment cycle, typically a second application 7–10 days after the first, to eradicate hatching nits.
Supportive measures reduce secondary irritation. Apply a soothing, fragrance‑free moisturizer or calamine lotion to calm inflamed skin. Avoid scratching to prevent bacterial infection. Wash all bedding, clothing, and personal items in hot water (≥ 60 °C) and dry on high heat. Items that cannot be laundered should be sealed in a plastic bag for two weeks, depriving lice of a host.
Environmental control extends to hair accessories, brushes, and combs. Soak these in hot water for at least 10 minutes, then dry thoroughly. Vacuum carpets and upholstered furniture to remove fallen nits. Regularly inspect all household members; treat any additional carriers promptly to halt re‑infestation.
Monitoring after treatment is essential. Examine the scalp 24 hours after the second application. Absence of live lice and nits indicates successful eradication. Persistent itching without visible insects may signal a secondary skin condition; consult a healthcare professional if symptoms continue beyond two weeks.
