What should you do if your scalp itches after having lice? - in detail
If the scalp remains itchy after a lice treatment, follow these steps to relieve discomfort and prevent re‑infestation.
First, verify that all live insects and eggs have been removed. Use a fine‑tooth comb on damp hair, starting at the scalp and moving toward the ends. Examine the comb after each pass; any nits or crawlers should be discarded. Repeat the process daily for at least a week.
Second, apply a topical anti‑itch agent. Over‑the‑counter products containing hydrocortisone 1 % or calamine lotion can reduce inflammation. Apply according to the package instructions, usually two to three times daily, and wash the area gently with mild shampoo before each application.
Third, keep the scalp clean and dry. Wash hair with a regular or medicated shampoo at least once every 24 hours. After washing, towel‑dry thoroughly; moisture encourages itching and may foster residual lice survival.
Fourth, treat secondary irritation. If the skin appears irritated, use a fragrance‑free moisturizer or an emollient containing aloe vera. Avoid scratching, which can break the skin and introduce bacterial infection.
Fifth, eliminate potential sources of re‑contamination. Wash all clothing, bedding, and towels used during the infestation in hot water (minimum 130 °F/54 °C) and dry on high heat. Seal non‑washable items in a sealed plastic bag for two weeks.
Sixth, consider adjunctive remedies if itching persists. Oral antihistamines such as diphenhydramine can be taken according to label dosage to control severe itch. A short course of a mild oral corticosteroid may be prescribed by a healthcare professional for intense inflammation.
Seventh, monitor for signs of infection: redness spreading beyond the scalp, pus, fever, or severe pain. If any of these appear, seek medical evaluation promptly.
Finally, document the timeline of treatment and symptoms. Note when itching began, what products were used, and any changes in severity. This record assists healthcare providers in diagnosing persistent issues and adjusting therapy.
By systematically confirming eradication, treating inflammation, maintaining hygiene, and seeking professional care when necessary, the itching associated with a recent lice episode can be effectively managed.
