How long have you been on minoxidil when you noticed this? I had been on Rogaine Minoxidil for only a week when I noticed similar hairs. But I'm not getting my hopes up too high; however, I am rooting on these little guys. Also, I've not noticed any shedding from the Minoxidil (twice a day for two weeks now) and my hair already feels thicker. Maybe I'm not thinning and just had a bad haircut (yeah, right).
