Trichotillomania specifically involves which behavior?

Trichotillomania, classified under obsessive-compulsive and related disorders in the DSM-5, is characterized specifically by recurrent hair pulling that results in noticeable hair loss. This behavior often serves as a means for individuals to cope with stress or anxiety, reflecting an irresistible urge to pull out hair. The act of pulling hair can lead to significant distress or impairment in social, occupational, or other important areas of functioning. The focus on hair pulling is central to understanding trichotillomania, setting it apart from other disorders such as skin picking or social withdrawal, which are indicative of different psychological conditions.
