Do you find yourself unconsciously biting your nails during stressful meetings? Maybe you pick at your skin while concentrating, or pull at your hair when feeling anxious? If so, you're definitely not alone. These behaviors are called Body-Focused Repetitive Behaviors (BFRBs), and they're much more common than you might think.

Recent studies show that 97% of people do at least one BFRB behavior at some point in their lives. Even more surprising? About 24% of people have clinically significant BFRB disorders. Understanding the most common BFRBs is your first step toward recognizing, managing, and treating these behaviors.

This guide will walk you through the five most common BFRBs, what they look like, how they affect your daily life, and what treatments actually work. Whether you're dealing with these behaviors yourself or trying to help someone you care about, this information can help you take the first steps toward getting better.

Understanding common repetitive behaviors

What are BFRBs really?

Body-focused repetitive behaviors are essentially self-grooming activities that have gone too far. We all do things like bite our nails occasionally or pick at a scab. But BFRBs become a problem when they happen so often that they damage your body and make your life harder.

Think of it this way: everyone scratches an itch sometimes. But if you're scratching so much that you create open wounds, can't focus at work, or avoid social situations because of how your skin looks, then it's moved beyond normal behavior into BFRB territory.

The main difference between BFRBs and other repetitive behaviors (like those in OCD) is pretty simple. With BFRBs, you're not usually responding to scary thoughts or following complicated rituals. Instead, these behaviors often help you deal with emotions like stress, anxiety, or even boredom.

What makes BFRBs different?

Most BFRBs share some key features that help us understand them better:

Two types of behavior: Sometimes you might do these behaviors without even realizing it, like biting your nails while watching TV. Other times, you might do them very deliberately, paying close attention to every detail.

Emotional help: These behaviors usually serve a purpose. They might help you feel calmer when you're stressed, give you something to do when you're bored, or make you feel more in control when life feels overwhelming.

Real damage: All serious BFRBs cause visible damage to your body and make parts of your life more difficult. This could mean avoiding handshakes, having trouble at work, or dealing with medical problems.

Complete BFRB overview: Body Focused Repetitive Behaviors list

The five most common BFRBs affect millions of people worldwide. Each one has its own patterns and challenges, but they all share the core features we just discussed. Here's what you need to know about each one:

  1. Nail biting (Onychophagia): The most widespread BFRB
  2. Skin picking (Dermatillomania): Often starts with acne or minor skin issues
  3. Lip and cheek Biting: The "hidden" BFRB that others can't see
  4. Hair pulling (Trichotillomania): Can affect any hair on the body
  5. Nose picking (Rhinotillexomania): The most stigmatized but still serious BFRB

Let's dive deep into each one so you can understand what to look for and how to get help.

1. Nail Biting

How common is nail biting?

Nail biting is the champion of BFRBs: about 11.4% of people have it severely enough to be considered a disorder. If we count people who bite their nails sometimes, that number jumps to around 30% of everyone.

This behavior hits its peak during young adulthood (ages 18-29), and women tend to do it slightly more than men. Stressful environments often make nail biting worse, which explains why so many people notice it getting worse during exam periods, job changes, or family stress.

What nail biting looks like

Recognizing when nail biting has become a real problem means looking beyond just short nails:

What you can see: Your nails might be bitten down to the quick, with red, swollen skin around them. You might get infections often, have scars around your cuticles, or even permanent nail damage in severe cases.

How it happens: Many people develop specific patterns: maybe they focus on certain fingers, or they look for hangnails and rough spots to bite. Some people have elaborate routines, examining their nails carefully before biting.

Extra behaviors: Many nail biters also bite their cuticles and actually swallow the nail pieces they bite off. This combination can cause additional health problems and usually means the problem is more serious.

Why nail biting is a big deal

Chronic nail biting affects your life in ways that go far beyond appearance:

Health problems: Your bitten nails create open wounds that let bacteria in, causing frequent infections. The constant contact between your teeth and hard nail material can also damage your teeth and even change how they're aligned.

Social impact: Many people with nail biting problems hide their hands, avoid handshakes, or won't do activities that might draw attention to their fingers. In work situations, this can hurt your career and networking opportunities.

Emotional stress: Because nail damage is so visible, many people feel ashamed, embarrassed, and like they have no self-control. This creates a frustrating cycle where the stress about nail biting actually makes the nail biting worse.

How to treat nail biting

Good news: nail biting responds really well to treatment when you use the right approach:

Proven methods: Habit Reversal Training (HRT) is the gold standard treatment. It teaches you to notice when you're about to bite your nails and do something else instead. When done properly, it works for 60-80% of people.

Technology help: New tools like the Hands Off app use AI to watch for nail biting through your webcam. When the app sees your hands going toward your mouth, it immediately shows you a reminder on your screen. This real-time intervention helps catch the behavior before it becomes automatic.

Success rates: With the right treatment approach, most people can significantly reduce or completely stop nail biting. The key is finding the right combination of awareness training, alternative behaviors, and environmental changes that work for your specific situation.

2. Skin picking

The reality of skin picking

Skin picking disorder affects 8.2% of people at clinical levels, making it the second most common BFRB. This condition strongly favors women, who are much more likely to develop dermatillomania than men.

The behavior often starts during the teenage years, frequently when someone has acne or other skin conditions. But here's the tricky part: the picking usually continues long after the original skin problems are gone, becoming its own separate issue.

Many people with skin picking also deal with anxiety, depression, or other BFRBs at the same time. Having existing skin conditions like acne, eczema, or those little bumps on your arms (keratosis pilaris) can trigger the initial picking behavior.

What skin picking looks Like

Skin picking disorder shows up in several recognizable ways:

Where it happens: About 75% of people with this disorder focus mainly on their face, but arms, hands, and other easy-to-reach areas get targeted too. Where someone picks often depends on their skin condition, what they can reach, and privacy.

Tools used: While fingernails are most common, many people graduate to using tweezers, pins, needles, or other tools. Using tools usually means the disorder is more severe and increases the risk of infection and scarring.

Ritual behaviors: Skin picking often involves detailed routines: spending long periods looking in mirrors, needing specific lighting, and carefully examining skin for any imperfections. These rituals can eat up hours of each day.

The real impact of skin picking

Chronic skin picking creates problems that spread into every area of life:

Skin damage: Repeated picking leads to scarring, dark spots, and wounds that can take weeks or months to heal properly. The constant trauma prevents normal healing and can create permanent damage to your appearance.

Infection dangers: Open wounds from picking are perfect entry points for bacteria, leading to serious skin infections, abscesses, and in bad cases, infections that spread through your whole body and require hospital treatment.

Social problems: Many people develop complex strategies to hide their skin damage: heavy makeup, strategic clothing choices, and avoiding social situations entirely. This avoidance can severely hurt relationships, career opportunities, and overall quality of life.

Treating skin picking

Effective treatment for skin picking needs to address both the behavior and the skin damage:

Specialized therapy: Modified versions of HRT designed specifically for skin picking include awareness training, ways to control your environment, and developing alternative behaviors. Acceptance and Commitment Therapy (ACT) has also shown great results for this condition.

Medical support: Working with both mental health professionals and skin doctors ensures comprehensive care. Dermatological treatments might include proper wound care, infection prevention, and cosmetic treatments for scarring.

Digital tools: Apps specifically designed to track skin picking can help you identify patterns, triggers, and progress over time. Some include photo features to document healing progress, which can be very motivating.

3. Lip and cheek biting

Recognition challenges

Lip and cheek biting affects 7.9% of people at clinical levels, but it's often missed because the damage stays hidden inside your mouth. Unlike other BFRBs, the evidence of cheek biting is invisible to others, leading to delayed recognition and treatment.

Research suggests that cheek biting might actually be the most common BFRB when you include milder cases, since the behavior often starts as a normal response to stress and gradually gets worse over time.

This condition has strong connections with stress and anxiety levels, often getting worse during periods of increased life pressure or emotional difficulty.

What cheek biting looks like

Identifying lip and cheek biting requires understanding both the visible and hidden signs:

Inside your mouth: The main signs happen where others can't see them: chronic sores, white or gray patches along your cheek lining, and areas of thickened tissue. These damage patterns have a distinctive look that experienced healthcare providers can recognize.

Physical discomfort: People often report pain while eating, drinking hot beverages, or eating spicy or acidic foods. The chronic inflammation makes normal mouth activities uncomfortable.

Behavior patterns: Many people develop specific biting patterns, targeting particular areas of their cheek or lip. The behavior often gets worse during concentration, stress, or when you have nothing else to do.

Treatment and management

Managing lip and cheek biting requires several different approaches:

Dental help: Dental professionals may recommend lip bumpers, mouth guards, or other protective devices to prevent access to the affected areas. These physical barriers can interrupt the automatic nature of the behavior.

Behavior change: Standard HRT techniques can work for mouth-focused BFRBs, though the hidden nature of the behavior requires better awareness training. You learn to recognize early warning signs and use competing responses.

Stress management: Given the strong connection with anxiety and stress, complete treatment usually includes stress reduction techniques like mindfulness, relaxation training, and cognitive behavioral therapy.

4. Hair pulling

Understanding hair pulling

Trichotillomania affects 1-2% of the general population, with lifetime rates reaching as high as 3.5%. This disorder strongly favors women, with a 10:1 ratio in adults, though boys and girls are more equally affected among children.

The typical start time is during adolescence, often coinciding with puberty and hormonal changes. However, it can begin at any age, with some cases starting in early childhood or emerging during periods of significant life stress.

Cultural factors play a big role in developing and maintaining trichotillomania, particularly in societies that place high value on hair appearance and grooming.

Recognizing hair pulling

Identifying trichotillomania involves recognizing both the pulling behavior and what it causes:

Hair loss patterns: Unlike medical causes of hair loss, trichotillomania creates irregular, uneven patterns of hair loss that may shift over time. The scalp is most commonly targeted, but eyebrows, eyelashes, and body hair can also be affected.

Hiding behaviors: People often develop elaborate strategies to hide hair loss – specific hairstyles, makeup application, wearing hats, or using wigs. These concealment efforts can significantly impact daily routines and social activities.

Related behaviors: About 20% of people with trichotillomania also eat their pulled hair (trichophagia), which can lead to dangerous intestinal blockages requiring medical intervention.

Specialized treatment for hair pulling

Treatment for trichotillomania requires specialized approaches that address the unique challenges of hair-focused BFRBs:

Modified HRT: Adaptations of standard HRT include enhanced strategies to control your environment, such as modifying hair accessories, changing hairstyles, or creating physical barriers to pulling. The treatment also incorporates cosmetic considerations and self-esteem building.

Family support: For children and teenagers, family-based interventions help parents understand the disorder and provide appropriate support without enabling or shaming behaviors.

Cosmetic help: Treatment planning often includes addressing the cosmetic impact of hair loss through wig consultation, hair growth treatments, or cosmetic techniques for enhancing remaining hair.

5. Nose picking

Understanding the stigma

Nose picking represents one of the most universally experienced but least studied BFRBs. While almost everyone picks their nose occasionally, compulsive rhinotillexomania is much less common but can cause serious health complications.

The extreme social taboo surrounding nose picking leads to significant underreporting and limited clinical research. Many people with compulsive nose picking never seek treatment due to embarrassment and shame.

The difference between normal nasal hygiene and compulsive behavior lies in frequency, intensity, and resulting damage. Clinical presentations typically involve multiple daily episodes that result in nosebleeds, tissue damage, or problems with daily functioning.

Health problems from nose picking

Despite being viewed primarily as a social issue, compulsive nose picking can cause serious medical complications:

Physical damage: Chronic picking can lead to frequent nosebleeds, holes in the septum (the wall between your nostrils), and structural damage to nasal passages. In severe cases, people may require surgery to repair damage.

Infection spread: Your nose is a primary entry point for respiratory germs. Frequent nose picking significantly increases your risk of catching and spreading infections, including COVID-19, flu, and common colds.

Secondary problems: Constant irritation can lead to chronic inflammation, increased susceptibility to sinus infections, and changes in how you breathe through your nose.

Managing nose picking

Treatment for compulsive nose picking focuses on practical interventions and harm reduction:

Better hygiene: Emphasis on proper nasal hygiene using saline rinses, humidifiers, and appropriate tissue use can reduce the perceived need for picking while maintaining nasal health.

Environmental changes: Simple changes like keeping fingernails short, using gloves during high-risk times, or applying barrier creams can interrupt the automatic nature of the behavior.

Alternative behaviors: Developing competing responses such as deep breathing exercises, fidget tools, or brief nasal saline application can provide alternative ways to address nasal discomfort.

Comparison: Nail Biting Trichotillomania Skin Picking

BFRB Type Prevalence Main Target Area Visibility Health Risks
Nail Biting 11.4% (clinical) Fingernails and cuticles Highly visible Infections, dental damage
Skin Picking 8.2% (clinical) Face, arms, hands Visible with scarring Scarring, infections, hyperpigmentation
Hair Pulling 1-2% (clinical) Scalp, eyebrows, eyelashes Variable with concealment Hair loss, intestinal blockages (if eating hair)
Cheek Biting 7.9% (clinical) Inside of mouth Hidden from view Oral pain, eating difficulties
Nose Picking Unknown (understudied) Nasal passages Socially visible behavior Nosebleeds, septal damage, infections

When multiple BFRBs happen together

Common Combinations

Research shows that about 45% of people with one BFRB also do additional body-focused repetitive behaviors. Common combinations include nail biting with skin picking, or hair pulling with cheek biting.

Understanding these patterns is crucial for treatment planning. If you only address one behavior while ignoring others, people often just shift their focus to a different BFRB. It's called symptom substitution.

The progression patterns vary, but many people report that their BFRBs evolved over time, beginning with one behavior during childhood or adolescence and expanding to include others during periods of increased stress or life transitions.

Treatment for multiple BFRBs

Effective treatment for multiple BFRBs requires careful consideration of whether to use unified approaches or behavior-specific interventions:

Unified approaches: Some treatment methods focus on the underlying mechanisms common to all BFRBs: things like emotional regulation, impulse control, and awareness training. These can be efficient for people with multiple behaviors.

Technology solutions: Apps like Hands Off can simultaneously monitor multiple BFRB behaviors, using AI detection to identify when hands approach various body areas including the mouth, nose, eyes, and ears. This comprehensive monitoring addresses the reality that many people engage in multiple BFRBs.

Family support: For children and teenagers, family education becomes even more important when multiple BFRBs are present. Parents need to understand how these behaviors are connected and avoid accidentally increasing shame or anxiety.

When to get professional help

Knowing when to seek professional help can make the difference between successful self-management and chronic struggle with BFRBs.

Warning signs: You should consider professional help when BFRBs cause physical damage, interfere with daily activities, create social or work problems, or cause significant emotional distress. Also, if you've tried to stop on your own repeatedly without success, professional guidance becomes essential.

Finding the right provider: Look for mental health professionals with specific experience in BFRBs, as these conditions require specialized knowledge and treatment approaches. Cognitive behavioral therapists, particularly those trained in HRT, tend to have the most relevant expertise.

Medical needs: In cases involving infection, scarring, or structural damage, medical evaluation is necessary alongside mental health treatment. Dermatologists, dentists, or primary care doctors may need to be involved in comprehensive care.

Prevention and early help

Early identification and intervention can prevent BFRBs from becoming deeply ingrained patterns that are harder to change:

Risk factors: Understanding that BFRBs often begin during periods of stress, anxiety, or major life transitions can help families and individuals recognize when additional support might be beneficial.

Education matters: Schools, healthcare providers, and families benefit from education about BFRBs to reduce stigma and improve early recognition. These behaviors are medical conditions, not character flaws or willpower failures.

Technology integration: Modern solutions like AI-powered detection apps can provide early intervention by catching behaviors before they become habitual. The immediate feedback helps maintain awareness and motivation for change.

Taking action against the most common BFRBs

Understanding the most common BFRBs: nail biting, skin picking, cheek biting, hair pulling, and nose picking, is your first crucial step toward recognition and treatment. These behaviors affect millions of people worldwide, yet they often remain untreated due to shame and lack of awareness.

The encouraging news is that effective treatments exist for all BFRBs. Whether through traditional approaches like Habit Reversal Training, modern technology-assisted interventions, or comprehensive integrated care, most people can achieve significant improvement in their symptoms and quality of life.

If you recognize yourself or a loved one in these descriptions, remember that BFRBs are legitimate medical conditions that respond well to appropriate treatment. The combination of professional support, evidence-based interventions, and modern technological tools offers unprecedented opportunities for recovery.

Your journey toward managing the most common BFRBs begins with the simple recognition that you're not alone and that help is available. Whether you choose to start with self-help strategies, technology-assisted solutions like Hands Off, or professional treatment, taking that first step toward awareness and action can transform these challenging behaviors from sources of shame into opportunities for growth and healing.
