What are the causes of rashes on the scalp?

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. In some cases, it can also indicate an underlying skin condition. If this is the case, it is best to schedule an appointment with a doctor so that proper assessment can be carried out.

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.
