Hey Sparky,
I work with some people with Trichotillomania. Things that have been recommended for them were to journal when they were doing the hairpulling; look at times of day, triggers, etc.; Once they are awarof when they are doing it, find other things to occupy their hands when they are most likely to pull - like needle work, drawing, coloring... Some of the OCD medications have targeted trichtillomania -Anafranil is the one that has been most sucessful with the people I know. Hope things get easier for our sister.
