Hi im 21 years old male and suffering from scaly and flaky scalp my dermatologist said it was scalp psoriasis but psoriasis medication such as aprezo 30 mg did not seem to work the only medication which was effective was iycotic 200 mg which is used to treat fungal infection for the past 3 months severity has increased in flaking the scales are yellow and hair loss and thinning os pronouncing what should I do is it misdiagnosis of seborrheic dermatitis with scalp psoriasis.
