Can someone tell what is this posoriasis name?

Hello, Last year I got posoriasis. It started with small pimples on both knees and both eyebows. Then after few weeks dandruffs started appearing on head. It spread fast and after 5-6 weeks it was on all head (even on eyebrows). Later on a spreading dry skin appear and also was on all body (near nose, on neck, on head). And last symptom was small pitches of red dry skin appearing everywhere. Some of them become larger. So any ideas what is this posoriasis?
