The symptom checker wouldn t respond after I put in the symptoms, so hopefully, you can help. I have had an extremely itchy scalp, redness/hot feeling, and some loss of hair on the top areas of my scalp. After two biopsies, the dermatologist couldn t come up with a diagnosis, just prescribed the usual treatments for patchy baldness. These help with the hair loss, but not the itching, which is sudden and intermittent. Any ideas?
