I used to pull out my eyelashes too, since I was a little girl, for as long as I can remember actually... then it escalated and I started pulling out my hair. Once I had no hairline or a new hairline depending on perspective.
Also used to pick my lips incessantly, and only stopped around age 15 when I started kissing boys and being worried about how broken they were... I still bite and pick the bottom lip when I'm stressed though, its broken right now actually.
These days I mentally slap myself when I start pulling at my hair, and only allow myself to indulge in light eyebrow tweezing and pretend its due to vanity....
