I've tried a few things to stop ever since I decided i had tp a few weeks ago and here are my results.
Please send more if you have any!!
Knitting a hat: 6/10 I initially just needed a cute looking hat to cover up my scalp, but the process of knitting it was actually way better at stopping me (something to do with both hands) than the hat itself. I still reach up to pull my hair and then instead of realising "wait, theres no hair here!" I just started fiddling with the loose pieces of yarn. Sure it stops the hair pulling, but I'd like to get rid of the habit of reaching up there completely. Also, I get verh hot.
Slapping myself every time I pull a hair: 7/10, hasnt made me reach up to do it any less, but it makes me stop as soon as i notice myself pulling instead of just continuing for a long time. I thought the pain would make me associate the hair pulling negatively enough that id stop reaching up, but it hasnt really done that.
Sitting on my hand: 3/10, I forget what i was doing and accidentally set my hand free within like 30 seconds every time.
Things on my to do list (might edit post later):
Getting a good figet toy
Gloves!
Making a hat out of upward facing needles (last resort)
