If you are an EMDR Institute trained clinician I suggest that you join the discussion list accessible through http://www.emdr.com
If you have been trained by that organization, or in the university setting or by another approved trainer, you are eligible to attend the EMDRIA Conferences and receive audio tape copies of the presentations. There have been a number of presentations on the use of EMDR with trichotillomania. Look for presentations by Carol York and by Marcia Whisman. There is also a case description in the new book called Small Wonders by Joan Lovett published by The Free Press/Simon & Schuster.
