yes...and scalp Psoriasis is so hard to treat (im a girl and have long hair....its tough to get ther creams they want u to put on 3 times a day in those hard to get at areas). i paid $75 a treatment for laser treatments at a dermatoligist that didnt take my insurance. I did about 15 treatments (they said it would only take 7-10) and i only saw minimal improvement.
