What are the causes of rashes on the scalp?

Fact Checked

It is a known fact that skin rashes commonly occur and do not always indicate a severe health problem. Essentially, skin rashes emerge due to exposure to an environmental irritant that causes the skin to swell and show symptoms of itchiness, flaking and small-sized bumps.

The affected area is red in color on the outer areas and lighter towards the center which provides its distinctive ring formation. Antifungal treatment is required since the fungus can spread to other parts of the scalp and even the body.
