What are the causes of scabs and sores on the scalp, and how can they be treated with over-the-counter shampoos and products?

Scabs and sores on the scalp can be itchy and uncomfortable. Scratching often makes the situation worse and increases the chances of infection. In many cases, scabs and sores on the scalp go away on their own or with over-the-counter (OTC) treatments. They usually do not indicate a serious illness. If you cannot identify the cause of the scabs and sores, or if they are spreading or appear to be infected, consult your doctor. Common causes include dandruff, lice, contact dermatitis, seborrheic dermatitis, psoriasis, seborrheic eczema, ringworm, head lice, lichen planopilaris, shingles, eosinophilic folliculitis, dermatitis herpetiformis, lupus, and skin cancer. Treatment varies depending on the cause. For dandruff, OTC medicated shampoos with ingredients like salicylic acid or tar can help. For lice, OTC medications specifically designed for lice treatment are effective. For ringworm, antifungal medications are needed. For conditions like psoriasis and eczema, medicated shampoos and topical ointments can provide relief. Always follow the instructions on the product packaging and consult your doctor if symptoms persist or worsen.
