Trichotillomania and Traction Alopecia
Trichotillomania and traction alopecia are chronic habitual disorders characterized by repetitive pulling of hair that results in alopecia. They are commonly observed in children and adolescents but may present in adults due to occupational or traditional behavioral patterns. Trichotillomania (hair‐pulling disorder) has been described more than a century ago, but we still have very limited data about its etiology and treatment. It is classified under the obsessive‐compulsive and related disorders along with hoarding disorder, skin‐picking disorder (excoriation) and body dysmorphic disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM‐5; American Psychiatric Association, May 2013). Traction alopecia is defined as loss of hair caused by repetitive or continuous and prolonged tension applied to the hair, usually on the scalp periphery and associated with mechanical traction of hair due to occupational behavioral patterns such as ballerinas or traditional behavioral patterns of hairstyles that cause tension. We aim to overview the clinical and diagnostic features of trichotillomania and traction alopecia and review the therapeutic options of these disorders in this chapter.
