Playing with the ends of my hair

Hi,
I was wondering if anyone else plays with the ends of their hair-Not in the twirling, pulling or combing through the hair way. I usually hold strands of hair between my index and middle finger while using my thumb to push against the tips of the hairs. I guess the feeling of the hairs hitting my thumb is quite soothing. It is the same feeling you get when you press against your eyelashes.

However, after a while the ends of my hairs get quite bent/curved by the constant pressure. I've done this for many many years on and off, but recently (past two-three years) it's been getting worse. I do it when i'm stressed, when i'm concentrating, and when i'm bored, so it's getting harder to stop. I have a very, very mild trichotillomania disorder (just eyelash pulling) and so i wonder if that may be the connection to this habit.
Overall, I'd like to know about your experiences and how you have controlled fidgeting with hair.
