This client's hair loss is caused by trichotillomania, or "trich" for short.
Trich is hair loss caused by compulsive hair-pulling and twisting, often with increased severity during times of emotional stress.
Although very common, it's something that's routinely mis-diagnosed by the medical profession as, for example, alopecia since patients don't always admit to "pulling".
There's much debate as to its root cause with some arguing that it's an Obsessive Compulsive Disorder (OCD) and others pointing to genetic factors.
However, we prefer to work on a client's head rather than in it because we believe that, whilst counselling has its uses, nothing increases self-esteem more than a full head of hair; allowing the client to be in a stronger emotional position to deal with the root cause of the problem.
