a little advice is to redirect those picking urges. i have trichotillomania and i told my therapist and one good way she recommended was to have something else to pick at. i have a jacket with those little beads of fabric on it, and everytime i get the urge i redirect it to that jacket and pick the beads of fabric off instead of my hair. ofc everyone is different, and this might not work for you but i hope it does, or that u can find some other way to help 💖💖
