Recently I've noticed that I get a lot of short, coarse, crinkly hairs right around my part and crown of the head. They are not just wavy, but tightly crimped, almost like pubic hair. They also come out very easily, so they are not like my normal hair at all, which is straight and fine. I am assuming this is some sort of breakage, but I have no idea what is causing it. I'd like to know so I can stop whatever I am doing!
