What can be applied to lice bites on the scalp? - in detail
Lice bites on the scalp cause itching, redness, and occasional swelling. Effective topical agents reduce inflammation, alleviate discomfort, and prevent secondary infection.
Topical corticosteroids such as hydrocortisone 1 % cream or ointment calm inflammation and limit itching. Apply a thin layer to the affected area three times daily for up to seven days, avoiding excessive use to prevent skin thinning.
Antihistamine creams, for example diphenhydramine 1 % gel, block histamine release and provide rapid itch relief. Use as directed, typically two to three times per day.
Moisturizing and soothing preparations support skin barrier function. Options include:
- Aloe‑vera gel – cooling effect, promotes healing.
- Calamine lotion – dries oozing lesions, reduces irritation.
- Zinc‑oxide paste – creates protective barrier, limits moisture.
Oral antihistamines, such as cetirizine 10 mg once daily, complement topical treatment by reducing systemic allergic response, especially when itching interferes with sleep.
Natural remedies may assist, provided they are applied cautiously:
- Diluted tea tree oil (0.5 % concentration) – antimicrobial, anti‑inflammatory; test on a small skin area first.
- Chamomile compress – brewed, cooled, and applied for 10 minutes, soothing pruritus.
Hygiene measures prevent recurrence:
- Wash hair with a mild anti‑lice shampoo, following the product’s instructions for contact time.
- Launder bedding, hats, and hair accessories in hot water (≥ 60 °C) or seal in plastic bags for two weeks.
- Vacuum carpets and upholstered furniture to remove fallen nits and larvae.
If lesions show signs of infection—pus, increased warmth, or spreading redness—consult a healthcare professional for possible antibiotic therapy. Continuous scratching can damage the scalp, leading to secondary infection; keeping nails short and using a soft brush to remove crusts helps maintain skin integrity.
