This is quite disgusting, but worried me slightly. The other night I pulled a hair (or what I believe to be a hair) out of my anus. It must have been 9-10 inches long. This has happened only once before, a few months ago, and at the time I didnt think anything of it, but now it has repeated I am a bit worried. I have read about eating hair during your sleep and the hair was around the same length and colour as my girlfriends, but I have also read about worms that look like hairs? Any help would be appreciated.
