Why does one have an itchy flaky skin in the scalp?
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: HIWell come to HCMLooking to the history given here this could be seborrheic dermatitis, most of the time  skin condition of the scalp being treated with combination of three agents, like steroid, antibiotic, antifungal, and the best option would be combination of " Neomycin, Beclomethasone, Minconazole, try this combination, hope this information helps, take care and have a nice day.
