I developed red bloches several places on my head inside my hair line, mainly on sides and front area. Some even appeared to look like ringworm but Derm Doctor said it was not ringworm. Used cortizone cream to control for awhile with several dandruff shampoos that did nothing to help. Then started using Selsun Blue Medicated and the rash cleared up quickly. It has not returned so I continue to use only Selsun Blue. You might want to try it.
