Overview
Trichotillomania (TTM) is a condition characterized by repetitive hair-pulling that causes visible hair loss, significant distress, and impairment in daily functioning. Often misunderstood and underdiagnosed, TTM can impact emotional well-being and lead to social and physical complications. This treatment manual offers a comprehensive approach to managing TTM by combining habit reversal training (HRT) and acceptance and commitment therapy (ACT). HRT teaches clients to recognize and interrupt pulling behaviors with alternative actions, while ACT addresses the emotional and cognitive factors driving the behavior, such as urges, stress, and psychological inflexibility. The program emphasizes skill-building, self-monitoring, and values-based action to reduce pulling and improve quality of life. Structured across ten sessions, it includes psychoeducation, trigger reduction strategies, acceptance of pulling-related experiences, and relapse prevention techniques. Research supports the efficacy of this approach, showing significant reductions in pulling severity and meaningful clinical responses in both individual and group formats.

Theoretical Background & Therapist Guidance
Trichotillomania (TTM), also known as hair-pulling disorder, is a chronic condition characterized by repetitive hair-pulling that leads to noticeable hair loss, functional impairment, and significant emotional distress (American Psychiatric Association, 2013). While historically under-recognized, recent research indicates a current prevalence rate of approximately 1.7% in the general population (Grant et al., 2020). TTM most commonly begins in late childhood or early adolescence, with an average onset between ages 10 and 13, and it often follows a chronic, waxing-and-waning course (Grant & Chamberlain, 2016; Stein et al., 1999). The disorder affects individuals physically, socially, and psychologically. Along with hair loss, common physical complications include scalp irritation, follicle damage, and, in extreme cases, trichobezoars, which can lead to gastrointestinal obstructions caused by hair requiring surgical intervention (Snorrason et al., 2021). Socially, individuals with TTM frequently report avoidance of public activities, interpersonal difficulties, and occupational impairment (Woods et al., 2006). Psychiatric comorbidities such as depression, anxiety, and substance use disorders are prevalent, affecting up to 80% of individuals with TTM (Houghton et al., 2016a).
This treatment integrates two empirically supported approaches: habit reversal training (HRT) and acceptance and commitment therapy (ACT). HRT focuses on disrupting automatic pulling behaviors by increasing awareness of triggers and implementing alternative, competing responses. ACT complements this by targeting the cognitive and emotional processes underlying focused pulling. Rather than attempting to suppress urges or uncomfortable emotions, ACT teaches clients to accept these internal experiences while committing to behaviors aligned with their personal values. This dual approach recognizes that TTM often involves both automatic and intentional pulling processes and provides targeted interventions for each (Grant et al., 2007; Flessner et al., 2008b). Research indicates that these approaches significantly reduce hair-pulling behaviors and severity, with most participants maintaining gains after treatment. Research also supports their adaptability, with group formats achieving high response rates and teletherapy yielding comparable outcomes to in-person sessions.
