Hi, I have plaque psiorsis on my face, arms, back, scalp and behind the ears. Scalp itches so bad and my hair is falling out and breaking, causes scalp to be super sore?

Dermatologist. Scalp involvement by psoriasis can be very troublesome and difficult to treat. Your psoriasis is severe enough to warrant evaluation and treatment by a dermatologist. New treatment modalities for severe cases are available.
