Thanks for the query.
From your description, there's a possibility of it being a fungal infection
Try to apply any anti fungal cream without steroids
, about 5 to 6 times a day over the oval areas. Continue for about 10 days. There should be some improvement. If there is no change, you can consult a dermatologist
. They will also suggest a suitable remedy for your dandruff
.Dandruff also is commonly caused by a type of fungus and you will benefit by the use of a special medicated shampoo like selsun.
Hope you are reassured.
