How to relieve itch after lice? - in detail
Lice bites trigger an inflammatory response that produces itching. Reducing that sensation requires a combination of topical relief, systemic medication, and environmental control.
First, cleanse the scalp with a mild, fragrance‑free shampoo. Rinse thoroughly and pat dry; moisture can worsen irritation. Apply a soothing agent such as 1 % hydrocortisone cream, calamine lotion, or a diluted solution of aloe vera. Limit application to the affected areas and avoid excessive rubbing, which can damage the skin barrier.
If the itch persists, consider an oral antihistamine (e.g., diphenhydramine 25 mg or cetirizine 10 mg). These agents block histamine release and diminish the sensory component of the reaction. Follow the dosing instructions on the package or those provided by a healthcare professional.
Additional measures that support relief:
- Cool compresses: place a clean, damp cloth in the refrigerator for 10 minutes, then apply to the scalp for several minutes.
- Oatmeal baths: dissolve colloidal oatmeal in lukewarm water and soak the head for 15 minutes; the beta‑glucans soothe inflammation.
- Moisturizing oils: a thin layer of coconut or jojoba oil can reduce dryness and prevent cracking.
- Avoid scratching: use a soft brush or fine-toothed comb to remove any remaining lice or nits, reducing mechanical irritation.
Maintain a clean environment to prevent re‑exposure. Wash bedding, hats, and hair accessories in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets and upholstery to eliminate fallen nits. Vacuumed items should be discarded or sealed in a plastic bag for at least 48 hours.
Monitor the scalp for signs of secondary infection, such as increased redness, swelling, pus, or fever. If any of these appear, seek medical evaluation promptly. Persistent or severe itching that does not respond to over‑the‑counter treatments also warrants professional assessment, as prescription‑strength corticosteroids or other targeted therapies may be necessary.
