well ,since there is no itching,then probably its a seborrheic dermatitis
.This condition in certain cases is associated with dandruff
.And it is seen in and around the eyebrows .But then if it was so then you should have responded to steroids
which you have already used.
In such circumstances where diagnosis is not very clear,I would first go with a KOH testing to rule out fungal infection
.This can be done at any pathology lab.If it comes positive then treat with any good anti fungal medicine.If it comes negative, then also I would firstly try and see the response with a oral anti fungal medicine (for 2wks) and the decide to give topical steroids.
Since all these medicines are not OTC preparations ,it is advisable to consult a dermatologist
who can see the lesions and decide best.
