What should be done if lice are on the head at home? - briefly
Apply a medicated shampoo or lotion approved for lice, then comb the hair with a fine‑toothed nit comb while wet, repeating the process every 2–3 days for two weeks. Wash all bedding, clothing, and personal items in hot water or seal them in a plastic bag for 48 hours to eliminate any remaining insects.
What should be done if lice are on the head at home? - in detail
Head lice infestations require immediate, systematic action to eliminate parasites and prevent re‑infestation. The following steps outline a comprehensive approach.
-
Confirm the presence of lice
• Examine the scalp and hair under bright light.
• Use a fine‑toothed lice comb, moving from the scalp outward.
• Look for live insects, nymphs, or eggs (nits) attached to hair shafts within 1 cm of the scalp. -
Apply an approved pediculicide
• Choose a product containing 1 % permethrin, 0.5 % pyrethrin, or dimethicone, following label instructions precisely.
• Apply to dry hair, saturating the scalp and strands.
• Leave the treatment on for the specified duration, then rinse thoroughly.
• Repeat the application after 7–10 days to target newly hatched lice. -
Remove nits mechanically
• After chemical treatment, comb the hair with a fine lice comb while the hair is still damp.
• Divide hair into sections, pulling the comb from scalp to tip to dislodge eggs.
• Clean the comb after each pass with hot, soapy water. -
Treat personal items and environment
• Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 60 °C) and dry on high heat.
• Seal non‑washable items in a sealed plastic bag for two weeks.
• Vacuum carpets, upholstery, and car seats; discard vacuum bags immediately.
• Avoid fumigation or insecticide sprays in the home, as they are ineffective against lice. -
Monitor and prevent recurrence
• Conduct weekly scalp inspections for at least four weeks.
• Instruct all household members to avoid sharing combs, hats, hair accessories, or pillows.
• Encourage regular use of a fine comb to detect any resurgence early.
By following these measures, the infestation can be eradicated efficiently, minimizing discomfort and reducing the risk of spread.
