2010 TRI/PRINCETON CONFERENCE 207 CONCLUSIONS HBI can be used as a tool for assessment of hair damage. It offers a fast and reliable non destructive option against the normal destructive methods for assessment of hair damage. The advantage of this method over the other hair damage assessment techniques is that it can performed directly on human volunteers and is helpful in evaluating the effi cacy of the product in clinical trials.
