Seborrheic Dermatitis Treatment?

i have Seborrheic Dermatitis over a year, there is a patch top of my head its small one but weird point is, i have no signs of early mpb, i’ve a matured hairline, not losing hair, i’m today 23 years old.

i heard about Seborrheic Dermatitis has no proven effective treatment is it true? its all about hormones?

There are good reviews of this problem at Google Health and Wikipedia.

Best to get educated and then visit a dermatologist to make what you read there personal.
