Ok ive had dry scalp for a long time now, and I've always tend to mess and pick on my head all the time, sometimes until it bleeds, so now I noticed that I have a small bald spot on top of my head, I was touching it and it looks like there is some stubble on there so hopefully it will grow back, Im just worried, never happen to me before and i have thick hair. Im going to buy Nioxin today, and I'm going to start taking BIotin. Has this ever happen to anyone.
