Hello. Thanks for writing to us at Chat Doctor Dan Chat Doctor.  While seborrhea dermatitis is associated with itching and yellow greasy adherent scales, psoriasis is characterized by well-defined patches, with thick scaling, commonly involving the hair line. In psoriasis there may plaques elsewhere on the body. The diagnosis is clinical, therefore a visit to a dermatologist would be useful in that regard. You may use an OTC antifungal shampoo e.g. 2% ketoconazole, alternate days, lather it well and leave it for 5 minutes to act before rinsing it off. If this doesn't seem to help you may seek an appointment with a dermatologist for a confirmatory diagnosis. Your dermatologist might also put you on topical steroid lotion for a period of about 2 weeks, if he or she feels that there is too much scaling and a shampoo alone might not be sufficient.Thereafter, once the scaling is effectively controlled with topical steroid lotion, a shampoo would be effective for maintaining the improvement.
