Hello!
I have had this problem for about twenty years now. I never had a doctor look at it because I am self conscious about it. My symptoms are reoccuring itchy, red, greasy areas on my scalp, eyebrows, eyelashes (lids), and pubic area. I notice the hair in those regions are very brittle and I feel a painful sensation from the roots. The hair easily comes out and attached to the end of the hair is an oblong off-white waxy/sticky substance. On my scalp, the symptoms occur in the same areas and are usually round in shape. What is this?
