I've never had this problem, but one of my close friends did. It's a condition known as trichotillomania. This is the pulling out of hair. When one eats it, it is an additional condition known as trichophagia. You can find a link to the trichotillomania learning center here. My friend also decided to make a YouTube video, explaining the condition and showing others that they are not alone. It can be found here. Good luck with everything! Feel free to shoot me a message if you need some support, or need someone to help you with research.
