Drying of the skin. A ringworm infection can cause the skin to become extremely dry. As the facial areas – as well as the shoulders and neck – are often affected, a sudden, unexplained drying of the skin in these areas could indicate ringworm. In some – but not all – ringworm infections, there is actually a loss of facial hair. This obviously occurs in males and can be quite traumatizing. If this begins to happen, you should consult your physician to treat a possible ringworm infection.
