After removing lice, the scalp itches – what should be done? - briefly
Treat the irritation with a gentle anti‑itch shampoo or cream—such as tea‑tree oil, aloe vera, or a low‑strength hydrocortisone formulation—and keep the scalp clean and moisturized. Avoid scratching and wash bedding in hot water to prevent re‑infestation.
After removing lice, the scalp itches – what should be done? - in detail
The scalp often continues to feel itchy after a lice treatment because the skin has been exposed to insects, their eggs, and the chemicals used to kill them. Irritation may stem from microscopic debris left behind, a mild allergic reaction to the pediculicide, or secondary inflammation caused by scratching.
First‑line measures focus on cleansing and soothing the skin. Rinse the hair thoroughly with lukewarm water and a gentle, fragrance‑free shampoo to remove residual product and dead insects. Follow with a mild conditioner if the scalp feels dry. Pat the hair dry with a clean towel; avoid vigorous rubbing, which can aggravate irritation.
To alleviate itching, apply one of the following options:
- Topical corticosteroid lotion (1 % hydrocortisone) applied twice daily for no more than a week.
- Calamine or menthol‑based lotion for a cooling effect, used as needed.
- Oral antihistamine (e.g., cetirizine 10 mg) if the reaction appears allergic; follow dosing instructions on the label.
- Cool compress (a clean, damp cloth chilled in the refrigerator) applied for five minutes, several times a day.
If the scalp remains inflamed, consider a short course of a non‑prescription antifungal or antibacterial wash to prevent secondary infection. Use products containing chlorhexidine or tea tree oil only if the child has no known sensitivities.
Environmental control prevents re‑infestation and reduces lingering irritants:
- Wash all bedding, clothing, and towels in hot water (≥ 60 °C) and dry on high heat.
- Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags immediately.
- Seal non‑washable items (e.g., stuffed animals) in a sealed plastic bag for two weeks to starve any remaining lice or nits.
Monitor the situation for 24–48 hours. If itching persists beyond a week, intensifies, or is accompanied by redness, swelling, pus, or fever, seek medical evaluation. A healthcare professional may prescribe stronger corticosteroids, prescription antihistamines, or investigate alternative diagnoses such as dermatitis or fungal infection.
