I'd second this suggestion. There can be multiple issues causing problems. I have both ADD and bipolar disorder. A lot of things that I thought were depression and ADD were actually bipolar. A lot of things that I didn't realize were just plain weird behavior were actually symptoms. Looking to see if there are other causes for unusual behavior is probably a good idea.

The hair pulling sounds like an OCD-related condition (trichotillomania) exacerbated by the stimulants. Another thing to consider would be non-stimulant medications like Strattera (I'm not familiar with the one you named.)
