Tinea capitis: Ringworm of the scalp (tinea capitis) is a fungal infection of the scalp/hair shafts. The signs and symptoms of ringworm of the scalp may vary, but it usually appears as itchy, scaly, bald patches on the head. This is a highly contagious infection, most common in toddlers and school-age children. See your Dr for oral medication and shampoo that can treat this problem over 4 weeks. Griseofulvin.
