Overview
Trichotillomania (TTM) is a condition marked by repetitive hair-pulling that leads to visible hair loss, distress, and impaired daily functioning. Often misunderstood and underdiagnosed, TTM can affect emotional well-being and lead to social and physical difficulties. This treatment manual presents a structured approach using habit reversal training (HRT) and acceptance and commitment therapy (ACT). HRT helps clients recognize and interrupt pulling with alternative behaviors, while ACT addresses urges, stress, and inflexible thinking. The program builds skills in self-monitoring and values-based action to reduce pulling and improve life quality. Spanning ten sessions, it includes psychoeducation, trigger management, acceptance of urges, and relapse prevention. Research shows it reduces pulling severity and leads to meaningful clinical improvement in individual and group settings. Designed for therapists with behavioral training, this evidence-based guide offers a practical and flexible framework for effectively treating TTM.

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 manual 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.
