A new study reveals that trichotillomania, a condition causing compulsive hair-pulling, is strongly linked to boredom and tiredness rather than just emotional distress, according to research published in Comprehensive Psychiatry. The findings challenge previous assumptions about the disorder’s triggers, highlighting the need for broader understanding of its underlying mechanisms.
Trichotillomania, a body-focused repetitive behavior that affects 1-2% of the population, has long been associated with emotional regulation. However, a recent study from Heidelberg University Hospital suggests that factors like boredom and fatigue may play a more significant role than previously thought. The research, which tracked 61 adults with the condition over 10 days, found that strong urges to pull hair were more predictive of episodes than negative emotions like anxiety or sadness.
The Study’s Key Findings
The study, led by researchers at Heidelberg University Hospital, used ecological momentary assessment to capture real-time data from participants. Instead of relying on evening journal entries, participants received seven prompts daily to report their emotional state, urge strength, and hair-pulling activity. This method revealed that boredom and tiredness were significant predictors of hair-pulling episodes, while negative emotions were less consistently linked to the behavior.
States of low energy may contribute to vulnerability for urges,
the researchers wrote, emphasizing that repetitive behaviors like hair-pulling could serve as a way to regulate internal stimulation. The study also noted that previous research had focused heavily on the behavior itself, neglecting the underlying urges that drive it. This gap in understanding led the team to prioritize capturing the “urge” in their analysis.
Personal Impact and Social Stigma
Ruben Chorlton-Owen, a 24-year-old with trichotillomania, described the emotional toll of the condition in a BBC interview. I remember looking in the mirror thinking 'what have I done?' I began avoiding photos and sometimes wore a cap to hide thinning patches,
he said. His experience reflects the broader stigma surrounding the disorder, which often leads individuals to hide their symptoms. shouldn’t be ashamed
Chorlton-Owen added, urging others to seek help without embarrassment.
Treatment and Broader Implications
Harvard Health’s overview of trichotillomania underscores the condition’s impact on daily life, from job performance to social interactions. The article notes that while some cases are mild, others can be debilitating, with individuals avoiding opportunities or relationships to conceal their symptoms. Because of the embarrassment, some people won't socialize or take promotions at work because they don't want to be in front of people,
said Nancy Keuthen, director of the Trichotillomania and Excoriation Disorder Program at Harvard-affiliated Massachusetts General Hospital.

Treatment options include cognitive behavioral therapy (CBT) and, in some cases, medication. Keuthen stressed the importance of seeking professional help, particularly when the behavior disrupts daily life. If it's happening repeatedly and you can't control it—if it's taking a bite out of your life, physically or emotionally—it's worthwhile to get it evaluated,
she said. The Harvard article also noted that trichotillomania is often linked to other conditions like anxiety, depression, and OCD, further complicating its management.
Limitations and Future Research
The Heidelberg study had several limitations, including its small sample size (61 adults) and the fact that participants were predominantly female. The researchers acknowledged that the 10-day monitoring period might have missed rapid changes in emotions or urges, as assessments were spaced up to four hours apart. Additionally, the study’s focus on a motivated sample may not fully represent the broader population of individuals with trichotillomania.

Despite these constraints, the findings offer new insights into the condition’s triggers. By shifting the focus from emotional distress to states of under-arousal, the study challenges existing models of trichotillomania. The consistent predictive role of boredom and tiredness in particular suggests that models focusing exclusively on emotional dysregulation may be insufficient,
the researchers concluded. This could pave the way for more targeted interventions and a deeper understanding of the disorder’s mechanisms.
