Scalp puller of 13 years, I'm 23 now. I've only ever went 4 days without pulling before, but I've limited how much I pull day to day. Anywhere from 2-20 a day. May not seem like a lot, but I've managed to keep from having a bald spot this way. Hair is very thin where I pull though and at a number of different lengths. Some days I break down, cry, and throw my hair up in a tight bun so it hides my spot and keeps me from pulling. Seems to be the only way to stop the urge for awhile. It's like a burn or an itch. I get anxious, short breathed and/or restless legs if I try to stop. I've not given up, just accepted that this is who I am. I am not weak for it. I may never be pull free (even though that's the goal) and that's ok.
I have so much more to add, and If you'd like to hear the rest of is, let me know! We can get through it together!
