I used to pull my hair out when I was younger. I don't know exactly what made me stop, but I have not purposely pulled it out in a long time now. I pulled out so much hair in my early teens that the top of my head was almost bald. Seems I have given up pulling for the equally disturbing habit of picking. I pick scabs, pimples.. nothing has a chance to heal with me. That actually felt good to get out. Wow.
