Signs and Symptoms
The most common locations for scalp ringworm include:
  • Scalp
  • Eyebrow (rare)
  • Eyelashes (very rare)
Scalp ringworm appears as one or more round to oval areas covered with gray sheets of skin (scale) and is often accompanied by hair loss. The patches may be red and inflamed, and small pus-filled bumps (pustules) may appear. Also, tiny black dots may appear on the surface of the scalp, consisting of broken hairs.

Certain areas (lymph nodes) at the back of the scalp, behind the ears, or along the sides of the neck may be swollen.

One complication of scalp ringworm is a kerion, which is a large, oozing, pus-filled lump. If not treated aggressively, a kerion can lead to scarring and permanent hair loss.

Scalp ringworm is usually itchy.
