I've tried some different things to stop but what worked for me was really a mind set. I pulled for about ten years. I never went to a dr. for it but I plucked my eyelashes, eyebrows, and other areas bald. I felt a strong urge to do it, sometimes I almost didn't even realize it, and felt stress releif when I did it. I didn't eat the hairs but I liked to "hunt" for fat roots and it became a bit of an obsession. Sometimes I'd touch the roots to my lips but I didn't eat them. Anyway, I am thoroughly convinced I had Trich, and here's what I did to stop:
I tried physical distractions like chewing gum or putting socks on my hands at night, but I personally think trich is a mental deal. See, I read about it online. People kept saying "I CAN'T stop". I thought about that, and let me ask you a question. Does your hand literally force itself to pull? As in, if you wanted to stop it, you'd have to physically grab it with your other hand or something? Heck no, not for me anyway. Even if it felt like my hand kinda found it's way up there by itself, I knew part of me decided to do it and could stop it. I didn't like the implication that I literally could not control my hand, because I didn't think that was true. Secondly, I saw a woman that was worried about her hair not growing back. I guess I always assumed that if I stopped, it would grow back. But basically, the sooner you stop, the better, the LONGER you stop, the better, because I saw something about how the follicle can repair itself some. So basically, if I was going to stop, which I wanted to do, I would have the best results if I stopped soon and didn't go back. But if I didn't stop for several more years, even after the hard work to stop, my hair may never look normal and that would bother me. So wanting to optimise my recovery was another big factor, and why I haven't gone back. I don't want to start again and do just enough more damage to cause permanent damage. I don't know how much my hairs can take and I don't want to risk it! The last factor that helped me stop was the social one. It's embarassing if people see, and one way or another, I'd have to tell my future boyfriend or husband or whatever. What would he think? I reasoned that I'd much rather tell someone that I USED to struggle with trich but overcame it then to still have it.
So that's it, I was almost offended by the idea that I was incapable of stopping my own hand from pulling, I wanted to give my hairs the best chance of recovery, I feared any more damage could be enough to cause permant damage, and I wanted to put this whole thing behind me as something I conquered instead of struggled with. It worked

I pulled off and on for 10 years, but after I've stopped, my eyelashes look normal, my eyebrows look normal, and I have long thick hair on my head. I love to twist my hair in my fingers but I don't want to pull them. Twisting is a new habbit that isn't distructive but is still soothing to me

Oh, and I told my crush, and he took it well and seems to have even forgotten about it

I'm free of the embarassment and I pray to God this maybe helps some of you get there too!!
P.s. And the urges get smaller and smaller as time passes. After the first day or so it starts to get easier I promise, just value each day and count up to your first week of being pull-free, first month, etc. If you relapse, just try again, but at least try to make it a longer stretch next time.
