Ringworm (tinea capitis) is a contagious fungal infection occurring most commonly in children, according to the American Academy of Dermatology (AAD). Over-the-counter remedies, such as anti-fungal powders and creams containing clotrimazole or miconazole, may be effective for treating the infection, according to Medline Plus. However, some individuals may need oral medications to relieve stubborn cases of ringworm.
Appearance
Ringworm is not caused by a worm; rather, it gets its name from the rounded shape of the fungus, which may have the appearance of a worm. Red borders define the edges, while the inside of the skin may appear normal.
Effects
Ringworm causes itching, redness and scaling of the skin.
Location
Ringworm can appear anywhere on the skin, scalp or nails, according to Medline Plus. When the nails are affected, they may become discolored and thick, sometimes crumbling.
Hair Loss
Ringworm that appears on the scalp can cause hair loss.
Misconceptions
According to the AAD, severe dandruff can sometimes be confused with ringworm of the scalp. However, ringworm may also cause inflammation and boil-like cysts to develop, according to the AAD.
