How to scratch the itch from lice? - in detail
Lice bites trigger an allergic reaction to the insect’s saliva, producing a persistent, often intense, sensation that leads to scratching. Relieving this discomfort requires a two‑fold approach: eliminating the parasites and soothing the skin.
First, eradicate the infestation. Apply a pediculicide approved for head lice according to the product label, typically a 10‑minute exposure followed by thorough combing with a fine‑tooth lice comb. Repeat the treatment after seven to ten days to capture any newly hatched nymphs. Wash all personal items—clothing, bedding, towels—in hot water (minimum 130 °F/54 °C) and dry on high heat for at least 20 minutes. Seal non‑washable items in sealed plastic bags for two weeks to starve any remaining lice.
Second, address the itch directly.
- Keep fingernails trimmed short to reduce skin damage.
- Apply a cold compress to the affected scalp for 5–10 minutes, several times daily, to numb the area and decrease inflammation.
- Use over‑the‑counter antihistamine tablets (e.g., cetirizine 10 mg) or topical antihistamine creams to counter the allergic response.
- Apply a low‑potency corticosteroid ointment (e.g., 1 % hydrocortisone) to inflamed spots no more than twice a day for up to one week.
- Moisturize with a fragrance‑free, hypoallergenic lotion to restore the skin barrier and lessen irritation.
- Avoid hair products containing alcohol, menthol, or strong fragrances, which can exacerbate itching.
If symptoms persist beyond a week, intensify, or show signs of secondary infection—such as increased redness, swelling, or pus—consult a healthcare professional for prescription‑strength therapy or antibiotics.
Combining thorough parasite removal with targeted anti‑itch measures restores comfort and prevents further skin trauma.
