My friend's daughter started doing the same thing when she was a teenager. There is a name for it and you can go onto the internet to find out more about it. It is called Trichotillomania. About the same time, my friend's daughter was diagnosed with it there was an article in Good Housekeeping about it. Some kids actually will start pulling their hair out too. At the time, they wanted her to do some counseling and take some medicine. She didn't want to do either so much of the time she was without eyelashes and eyebrows. The girl is now 25 and yes, she did outgrow the compulsion to do it.
I would imagine there are new things they are doing to help those with this. I hope you find something on the internet that can help!
I found a parents page on one site - the link is here.
