back of my scalp I have itchy flaky skin
Patient: On the back of my scalp I have itchy flaky skin. It spread to the back of my neck about 3/4 of an inch down and maybe 1 and 1/2 inches across. This spot on my neck is itchy and flaky, as well as red around the edges. I m using head and shoulders shampoo and it has improved some but it s not clearing up well. Do you think this is dandruff, psoriasis, ringworm or something else. Doctor: HI  WELCOME TO HEALTHCAREMAGIC   Ring worm infection cause loss of hair in the site of infection. it usually round and the edges are red .  Dandruff can  spread  down. It has scales.  Psoriasis is usually located on elbows and knees. But it can happen on scalp.  It is tough to diagnose without physically looking at the rash.  Regards, Dr. Jagdish
