Hair-Related Dysmorphic Disorder in a Patient with Bipolar Disorder

Introduction: Hair-related Body Dysmorphic Disorder (BDD) is a psychiatric condition characterized by an obsessive concern with perceived hair defects. It often leads to compulsive behaviors such as excessive mirror checking and avoidance of social interactions, significantly impacting self-esteem and quality of life. While Hair-related BDD frequently coexists with depression and anxiety, its association with bipolar disorder remains underexplored. This study presents a case highlighting this unique comorbidity. Case Report: A 66-year-old female patient initially presented in 2011 with telogen effluvium and experienced recurrent episodes of hair loss until 2021. Although her hair appeared normal during physical examinations, she developed heightened emotional distress and social withdrawal, particularly during depressive episodes. In 2023, she was diagnosed with bipolar disorder following an intense depressive phase, and in 2024, hair-related BDD was identified. Treatment with psychiatric medications, including an antidepressant for BDD, resulted in significant improvement in her symptoms.
