What to do if the head itches after lice? - in detail
Persistent scalp irritation after a lice infestation signals remaining eggs, residual chemicals, or secondary infection. Immediate measures focus on cleansing, soothing, and preventing further discomfort.
First, remove any remaining nits and adult insects. Apply a fine-toothed comb to damp hair, working from the scalp outward. Repeat the process every 12 hours for three days to catch newly hatched lice.
Second, wash the hair with a medicated shampoo containing permethrin or pyrethrin, following the manufacturer’s instructions precisely. Rinse thoroughly, then condition with a gentle, fragrance‑free product to restore moisture.
Third, alleviate itching through topical agents. Apply a 1 % hydrocortisone cream or a calamine lotion to the affected areas no more than three times daily. For severe inflammation, a short course of oral antihistamines may be prescribed.
Fourth, disinfect personal items. Soak combs, brushes, and hair accessories in hot water (minimum 60 °C) for at least 10 minutes. Machine‑wash bedding, towels, and clothing on the hottest cycle compatible with the fabric, then dry on high heat.
Fifth, monitor for signs of infection: redness spreading beyond the scalp, pus, fever, or swelling. If any of these symptoms appear, seek medical evaluation promptly.
A concise protocol:
- Comb hair with a nit comb every 12 hours for three days.
- Use a permethrin‑based shampoo, rinse, and follow with a mild conditioner.
- Apply 1 % hydrocortisone or calamine lotion, max three applications per day.
- Treat secondary inflammation with oral antihistamines if needed.
- Clean all personal items in hot water or high‑heat dryer settings.
- Observe scalp for infection indicators; consult a healthcare professional when present.
Adhering to this regimen reduces itching, eliminates residual parasites, and minimizes the risk of secondary complications.
