I did the same thing. I have periods where I stop and then pick it up again. At the moment, I have stopped (but am strongly skin picking). I hated myself for it and criticized myself over constantly. Then it would get worse. I still hate myself for having the occasional habit of putting my fingers to my hair, even once in a blue moon pulling out a hair. Somehow I have convinced myself that I had a logical reason for doing this, and even sometimes couldn't understand (and still can't for many OCD traits) why others (normal people) don't feel the same urge to get rid of the coarse hairs, or grey hairs, or hairs that are in a place where I feel a pulling feeling. Right now, I am successful in avoiding the trich. I think it is bc I am focusing on something else. Maybe it's the skin picking, or focusing on work. I find that if I can find a productive obsession (bc I am either obsessed or not interested at all), it takes my need to find satisfaction in air pulling away bc I am getting satisfaction somewhere else. Try finding something you can focus on that gives you the same satisfaction of pulling (therefore relieving anxiety) and that may also be productive. Sometimes, also, it is about convincing yourself to obsess in the opposite direction. For example, I am convinced that by squeezing pimples that I will finally get rid of them all and have a clean slate to create the perfect completion. I am going to try to change my thikning about this. Convince myself that there is another way to perfection - like a rigid skincare routine. It is hard, but it is something I am going to try. Maybe you can replace your pulling with a haircare routine that in some way (through trial and error - you need to find what works for you) satisfies the release of anxiety.
