Hi Katix3 - It's great that you found this forum. And that you have been able to explain your hair-pulling behaviour. And you've done some research already to inform yourself about it. You can tell us here on the forum - this is a pretty good forum with lots of people who will listen. My advice for you is this - it's important for you to realize that you can stop the hair-pulling, you can control what your hands are doing. Your hands don't do the hair-pulling on their own. You can enhance your awareness of what your hands are doing, and then change what they are doing. Decide to have your hands do something else. Here's a link that I found for you about trichotillomania - http://trich.org/dnld/ExpertGuidelines_000.pdf and it has some ideas such as a fidget item, and CBT (cognitive-behavioural therapy).
Hope there's something there that is useful for you.
