ABSTRACT
Trichotillomania is caused by the habitual, compulsive or intentional pulling and plucking of hair. Although it can be found in persons who are mentally or emotionally ill, many patients are healthy. However, with careful questioning, a history of significant stress or turmoil at school, home or work can often be obtained. Frequently, patients are school-aged children, and often both child and parents deny the possibility of pulling or plucking as a cause of hair loss. Therefore, a biopsy specimen can be crucial for establishing the diagnosis with certainty.
