I have PCOS and I"m taking aldactone, spinolactone The same thing, just two different names used and I take 100 mg./dayu. My hair loss comes and goes. I have months that are normal and months that are high shed. I notice I always have stuff in my scalp and I'm not sure what it is. You can't see it unlses you scratch the scalp and then all this white powdery stuff comes up out of my hair. Just wondering what that could be and how to help keep it out of control. it makes me fearful that maybe its sebum or something that's clogging my hair follicles and causing the hair loss. I feel like I can't use any gel or leaves in or anything.

Also, brushing, dry brushing, I hear some do it and I would like to for the good benefits of the sebum cleansing and oil movement, but my hair is fairly coarse and breaks easily, so what do you all think of dry brushing as a frequent treatment for hair and how do you do it without breaking.
