Ringworm can give you a very dry skin in the infected area. You may find that in the initial stage of having the infection, rashes occur but without any dryness of the skin. However, as the condition starts to progress, your skin begins to lose its natural moisture.
The dryness is due to the fungus that feeds on the keratin of your skin in order to grow and multiply. This removes the protective layers of the skin and creates rashes and dryness. Though ringworm is usually acquired in moist environments, once infected, it is recommended to moisturize around the affected area to ease dryness and other symptoms.
