Although there can be many causes of flaky rashes one of the most common causes is seborrheic dermatitis.  This rash is thought to be caused by an overgrowth of yeast on the skin.  It is most commonly found on the scalp, ears, and nose and in the beard area for men –is slightly yellow and may itch.  Treatment options include cream or shampoos.  If the area is very red and inflamed, we may prescribe a mild steroid cream for short periods of time.  Over the counter, we recommend Selsun Blue or Nizoral shampoo to use daily for maintenance treatment.
