hi, as you have already mentioned you are having seborrheic dermatitis
. Its a kind of dermatitis where in you get small red itchy elevated lesions along with sticky overlying scales. The lesions that you are having on your face are of seborrheic dermatitis only. What you need to understand is that it is completely curable and yes the hair fall
is reversible. Kindly continue with the treatment of antifungal shampoos and topical steroids
and once it is controlled still continue with antifungal shampoos to keep dandruff
at bay. Hope that answers your question.
