Talk to Dermatologist on Psoriasis

ASA. I have a problem regarding disease name Psoriasis which is from last 2 years on my head. I have checked by a doctor who started medication which was useful but for the time being. When i stopped medication,it started again. And now it is very severe specially on front side of my head. Please recommend me a good doctor or any remedy.

P.S Doctor told there is no 100% solution for this, But one of my friend had this disease on his hand, he is good now since last year.

Thanks & Regards: Mobeen Ahmad
