I have a "habit" of pulling in my eyebrows and lashes since I was a child.. I don't know f it's part of OCD. But my son... He compulsively strokes at his eyelashes when watching tv, doing homework, watching tv, at school. He's only been doing it for a couple months so I don't know what the trigger was for him...
He gets mad whether I gently prompt him to stop or flat out tell him to stop! If his fingernails are dirty Im concerned he will get an infection..
