Interesting this needs to be more known. I bet a higher percentage of people have it than any number could guess. Even when I look it up not much is discussed about it. So thinning eyebrows and all day scalp itching is the major symptoms? I feel I deal with both. My dermatologist doesn’t seem to examine my hair very hard but I will call to be on the safe side. I am thinning more so it could be a reason why. Is there a cure for this?
