I suffer from hair-pulling disorder

I dont pull my hair, I love scratching at the hair on my head, as it feels pleasurable-is this head m*********ion!?!
I cant/dont wear hair product as I cant stand not being able to run my hands fingers through my head, give my scalp a good massage/scratch. And no I dont have dandruff, dry scalp, problem hair or anything like that. Mind you I dont pull out my hair a la Mona Lisa, and I dont feel like doing that, although hair pulling is quite pleasurable too. I like it that I am a potential candidate for a diagnosis out of the DSM IV. Yay!
