What Is Scalp Ringworm?
Scalp ringworm, known in the medical world as tinea capitis, is a fungal infection of the scalp caused by different species of dermatophytes (fungus that causes disease).
Most cases of scalp ringworm occur in children between the ages of 3 and 7 years. It presents as many scaly flat areas and patches of broken hairs and bald spots on the scalp. In more severe cases, you may notice red bumps and pus-filled blisters as well as systemic symptoms like fever and malaise.
How Is It Diagnosed?
Ringworm is most commonly diagnosed by the doctor examining the skin. If the diagnosis is in question, a Wood’s lamp shining on the scalp hair will show a blue-green fluorescence with certain ringworm types. Collecting a scraping of the scalp skin to grow fungus in a culture will identify the specific fungus causing the ringworm.

How Is Tinea Capitis Treated?
Tinea capitis must be treated with antifungal medicines taken by mouth, because the organisms invade the hair follicle and cannot be reached by topical therapies.
Treatment usually takes 4-8 weeks due to slow growth of the fungus it takes a long time to get rid of it.
Antifungal shampoos may be used with medicines taken by mouth to decrease scale and contagiousness. Secondary bacterial infection can accompany ringworm which is treated with antibiotics by mouth.
How Is Tinea Capitis Prevented?
To prevent ringworm, don’t share clothing, sports gear, hair brushes, towels, or sheets. If you think your child has been exposed to ringworm, wash their clothes in hot water with special antifungal soap. Be sure to wash your child’s scalp regularly with shampoo, especially after haircuts.
