For millions of people worldwide, the battle with Body-Focused Repetitive Behaviors (BFRBs) is a daily reality—painful, persistent, and profoundly misunderstood. These behaviors, which include chronic hair pulling, skin picking, and nail biting, are far more than bad habits. They are complex mental health conditions that often go unrecognized and untreated, leaving sufferers trapped in cycles of shame, secrecy, and physical harm.

But recent research is challenging long-held assumptions about BFRBs. With advances in neuroscience, psychiatry, and personalized medicine, we are beginning to uncover the biological and psychological roots of these behaviors—and, crucially, how to treat them more effectively.

What Are Body-Focused Repetitive Behaviors?

BFRBs are a class of mental health disorders characterized by repetitive self-grooming behaviors that damage the body. The most common include:

• Trichotillomania: recurrent pulling out of one’s hair, often from the scalp, eyebrows, or eyelashes
• Dermatillomania (Excoriation Disorder): compulsive skin picking that leads to sores, scarring, or infections
• Onychophagia: chronic nail biting that can damage the nails, skin, and cuticles

Less common but related behaviors include cheek biting, tongue chewing, and lip picking.

What sets BFRBs apart from everyday grooming or occasional nervous habits is the level of distress and impairment they cause. People with BFRBs often try to stop but cannot, and the behaviors can interfere with relationships, careers, and emotional well-being.

A Silent Epidemic

Despite affecting millions, BFRBs are rarely discussed publicly and frequently misunderstood—even by medical professionals. Estimates suggest:

• 20–30% of people engage in nail biting to some degree, especially during childhood
• 2–5% of people live with trichotillomania or dermatillomania
• Many individuals experience more than one type of BFRB simultaneously

For decades, research into these conditions remained scarce, underfunded, and fragmented. As a result, many individuals have been misdiagnosed or dismissed, told that their behaviors are attention-seeking, unhygienic, or simply a lack of willpower.

In reality, BFRBs are now understood to be neurobiological conditions—linked to brain circuitry, emotional regulation, and potentially even genetics. This understanding is transforming how we approach treatment.

The Turning Point: The BFRB Precision Medicine Initiative

One of the most important recent efforts to understand BFRBs on a deeper level is the BFRB Precision Medicine Initiative—a multi-site, crowdfunded research project launched in 2017 and directed by Dr. Tara Peris at UCLA. With over $2.8 million raised largely through grassroots donations, the study represents the largest and most comprehensive investigation of BFRBs to date.

This initiative has involved:

• 300 participants, including those with BFRBs and healthy controls
• Clinical interviews to document the onset, severity, and emotional context of behaviors
• Genetic testing to search for biological markers
• fMRI brain scans to identify differences in brain structure and function
• Cognitive testing to assess traits like impulse control, attention, and reward sensitivity

The goal of the study is not just to understand what BFRBs are, but to break them down into meaningful subtypes. For instance, some individuals pick their skin in response to stress or anxiety; others pull their hair when bored or distracted. These differences suggest that BFRBs are not a single disorder, but a spectrum of related conditions that may require different treatment strategies.

By identifying distinct neural patterns and behavioral profiles, researchers hope to pave the way for personalized treatment—an approach that is sorely needed, given how often current methods fall short.

What Does the Brain Tell Us?

Emerging evidence from neuroimaging studies has begun to shed light on how BFRBs affect the brain. For example:

• People with low-awareness BFRBs—those who engage in behaviors automatically or unconsciously—show differences in brain areas associated with sensory processing and habit formation.
• Those with high-awareness or emotionally driven behaviors—such as pulling in response to perfectionism or stress—tend to have structural differences in regions related to emotional regulation, visual memory, and self-control.

This aligns with the lived experience of many individuals, who describe their behaviors as a way to relieve internal tension or to create a sense of relief, control, or satisfaction. However, the short-term relief is often followed by guilt, embarrassment, or physical pain—further deepening the emotional toll.

---

The Role of Anxiety and Comorbid Conditions

BFRBs rarely occur in isolation. They frequently co-occur with other mental health conditions, particularly anxiety disorders:

• Up to 20% of people with a BFRB also meet criteria for generalized anxiety disorder
• Around 13% are diagnosed with obsessive-compulsive disorder (OCD)
• Many report symptoms of depression, ADHD, or autism spectrum disorder

However, while anxiety is common among people with BFRBs, its severity doesn’t always correlate with the severity of the repetitive behavior itself. This suggests that BFRBs may not simply be symptoms of anxiety but distinct disorders with overlapping features.

---

Are We Any Closer to Effective Treatment?

Despite growing scientific interest, treatment options for BFRBs remain limited—and success rates modest:

• Habit Reversal Training (HRT), a specialized form of Cognitive Behavioral Therapy (CBT), is the most evidence-based treatment. It teaches individuals to become more aware of their behavior and to substitute healthier actions.
• Medications, particularly selective serotonin reuptake inhibitors (SSRIs), have had mixed results. Some individuals benefit, while others see no change.
• N-Acetylcysteine (NAC), an over-the-counter antioxidant, has shown promise in some small trials, particularly for hair pulling, by modulating glutamate in the brain.

However, long-term effectiveness remains low, with relapse rates high. One reason is that many therapists are not trained in treating BFRBs and may misapply standard anxiety or OCD protocols that don’t address the unique features of these behaviors.

This is why the Precision Medicine Initiative—and its potential to match individuals to the most appropriate interventions—represents such a breakthrough.

Reframing the Narrative

Perhaps the most important shift underway is a cultural and psychological reframe: understanding BFRBs not as a personal failing but as a legitimate medical condition. This shift allows people to seek help without shame and creates pressure for institutions to invest in more research, better treatments, and greater public education.

We now know that BFRBs are:

• Highly prevalent
• Neurobiologically based
• Often hidden due to shame
• Frequently misunderstood—even by professionals

But we also know that with the right support, people can gain control over these behaviors, reduce their impact, and reclaim their lives.

---

Where We Go From Here

As researchers begin to publish results from large-scale studies, and as awareness continues to grow through advocacy organizations and public voices, the outlook for people with BFRBs is finally beginning to brighten.

There is still a long way to go—but we now have a scientific foundation for hope.

If you or someone you love struggles with BFRBs, know this: you are not alone, and help is out there.
