Losing one’s hair. A ringworm infection tends to cause extreme hair-loss in any area where it occurs. Any portion of the skin that has a growth of hair is vulnerable to this. This includes not only obvious places like the scalp or the beard but also the eyebrows and pubis. Hair tends to fall out as the skin grows thick and dry.

Scales on the soles of one’s feet. When the feet are infected with ringworm, the infection usually manifests as patterns of scales, or at least the skin takes on the appearance of scales. The most common site of such an infection is the sole, though it can also occur on the side of the foot, or in between the digits. Such an infection could also occur upon one’s hand. If the infection occurs upon the hand, it might be limited to one hand. If the ringworm infection occurs upon the feet, it will commonly affect both feet.
