Today I found a very short, very hard, white hair toward the front of my head. I have felt similar hairs before, but being in the back of my head I could never see them. It was not painful to touch it, but it was annoying so I pulled it our with some tweezers. Now it hurts just a little bit. Kind of like something poked the top of my head.
After I pulled it out, it was about a 1/4 of an inch long. It looks like it is made out of a fingernail, and it is hard like fingernail material. I noticed many other people have these, but no one seems to know what they are. It is not attached to any other hair. It has its own follicle. Any ideas?
