Hi, may I answer your health queries right now ? Please type your query here...I'm not sure what I have. Although not really present at dermatologist visit, she said I have sebhoreic dermatitis. But I don't have dandruff. As most skin conditions of course its itchy, I do have oily scalp, if I leave it long enough without shampooing or with even some shampoos I get what I think look like pimples. In severe cases after long periods or some shampoos, when I scratch I get in my finger nails yelloish red clumps from the pimples which I feel on scalp. Can you tell what I have. And will it go away or is it permanent. How can I treat, or cure it? Thank you.
