Do you catch yourself picking your skin or pulling your hair when alone? Here is why it happens and how to find relief.

Do you often find yourself biting the skin around your fingernails, pulling out strands of hair, or chewing on your lips when you are bored or stressed? Many people think these actions are just nervous habits that will go away on their own. However, these repetitive body-focused actions can sometimes be much more complex than simple habits.

Today, we will talk closely about these repetitive behaviors that can unintentionally cause physical harm to your own body. In medicine, these actions are known as body-focused repetitive behaviors, or BFRB for short. Understanding what they are is the first step toward getting the right support and finding relief.

You are never alone if you struggle to stop these urges, and effective treatments are available to guide you toward healing. Let us explore what BFRBs mean, why they happen, and how doctors diagnose and treat them.

Common types of body-focused repetitive behaviors recognized in clinical practice.

What Are Body-Focused Repetitive Behaviors (BFRBs)?

Simply put, a BFRB is any repetitive action you perform on your own body that results in physical damage. Many people dismiss these actions as nervous tics. For example, you might chew the skin around your fingernails or crack your knuckles when you feel restless.

However, these actions are far more than simple ways to pass time. Research shows that our genetics, brain structure, and emotional state heavily influence why these behaviors occur. You might try to stop doing these things, but you may find them very hard to control.

BFRBs come with a powerful, almost irresistible urge that builds up inside you. Once you perform the action, you might feel a brief sense of satisfaction or relief. Do not worry, because if you need help managing these urges, effective medical treatments and therapeutic options exist.

What Are the Main Types of BFRBs?

Medical experts recognize several different types of body-focused repetitive behaviors. Among them, two primary categories are most commonly diagnosed and studied in clinical settings:

• Skin Picking: Clinically known as excoriation disorder or dermatillomania, this involves constantly picking, scratching, or digging at your skin.
• Hair Pulling: Clinically known as trichotillomania, this involves pulling out strands of hair from your scalp, eyebrows, or eyelashes.

The American Psychiatric Association outlines these two primary conditions in its diagnostic manual, the DSM-5-TR, which helps doctors make accurate clinical assessments.

Are There Other Types of BFRBs?

Yes, several other body-focused repetitive behaviors exist beyond skin picking and hair pulling. These additional behaviors include:

• Teeth Grinding: Medically called bruxism, where you clench or grind your teeth unconsciously.
• Finger Cracking: Often harmless, though some people make a daily habit of popping their joint knuckles.
• Skin Biting: Clinically known as dermatophagia, involving biting the skin around fingers or hands.
• Finger Sucking: More common in young children, though some adults retain this soothing habit.
• Lip Biting and Trauma: Chronic lip chewing that can lead to localized keratosis and sore tissue.
• Cheek Biting: Medically called morsicatio buccarum, where you chew the inside of your cheek.
• Nail Biting: Clinically referred to as onychophagia, which damages nail beds and cuticles.
• Nail Picking: Clinically known as onychotillomania, involving aggressive picking at fingernails.
• Nose Picking: Medically known as rhinotillexomania, which can cause nasal irritation and bleeding.
• Hair Eating: Known as trichophagia, where a person pulls and consumes their own hair.

While the DSM-5-TR does not list all of these specific variations individually, doctors readily classify them under the broader BFRB umbrella.

How Common Are These Conditions?

Various scientific studies show that between 0.5% and 4.4% of the general population experiences clinically recognized BFRBs. However, the true number of people affected is likely much higher.

Many people never seek professional medical advice for these issues. Some feel embarrassed to speak up. This others simply do not realize that these repetitive actions represent a recognized medical condition.

What Are the Symptoms of BFRBs?

Common signs and behavioral patterns associated with body-focused repetitive behaviors include:

• Pulling, scratching, or picking at your hair, skin, or nails on a regular basis.
• Biting your nails, lips, or inner cheeks until soreness develops.
• Cracking your fingers or grinding your teeth repeatedly.

When you perform these actions, you may experience specific emotional patterns:

• Feeling a strong sense of tension or anxiety right before you perform the behavior, followed by temporary relief once you finish.
• Feeling a complete loss of control while the action is happening, making it very difficult to stop.
• Performing the action with full conscious awareness at times, or doing it completely on autopilot without realizing it. For instance, you might pick at a piece of skin while watching television or reading a book without noticing until later.

Why Do BFRBs Happen? What Are the Causes?

Doctors and researchers do not yet have a single clear answer for why BFRBs develop. However, scientific research points to several contributing factors:

• Brain Structure and Genetics: Our brains contain specific circuits that regulate reward, satisfaction, and emotional control. Variations in the structure of these areas can trigger BFRBs. Our genes help determine how these brain regions develop and function. Genes also influence brain chemicals like serotonin and dopamine, which manage our moods and impulse control.
• Emotional Regulation: Sometimes, BFRBs serve as a physical coping mechanism that your body uses to process, manage, or escape difficult negative emotions like stress, sadness, shame, or boredom.
• Distraction and Sensory Stimulation: When you feel overwhelmed, anxious, or overstimulated, BFRBs can act as a grounding mechanism. They help redirect your focus away from emotional distress by channeling nervous energy into a physical task.

The most important thing to remember is that BFRBs do not happen because you want to change your physical appearance or look a certain way. Other psychological conditions relate to appearance concerns, but BFRBs function quite differently.

Who Is at Higher Risk for BFRBs?

Certain biological and environmental factors can increase your likelihood of developing a body-focused repetitive behavior:

• Being female, as research shows higher reported diagnoses among women.
• having severe trauma, abuse, or chronic stress during childhood or later life.
• Having a family history of BFRBs or related mental health conditions.
• having low self-esteem or chronic self-doubt.
• Living with obsessive-compulsive disorder or related anxiety conditions.
• Struggling with substance use disorders or alcohol dependence.

What Complications Can Arise from BFRBs?

Constantly biting, scratching, pulling, or picking at your body can lead to several physical and emotional complications:

• Bacterial Infections: Open wounds on your skin provide an easy entry point for harmful bacteria, leading to localized infections.
• Bleeding: Skin picking and nail biting often cause minor bleeding and painful raw spots.
• Hair Loss: Regular hair pulling creates noticeable bald patches or thinning areas on the scalp.

Complication Type.	Common Affected Area.	Recommended Action.
Skin Damage.	Face, arms, hands.	Keep clean, apply antiseptic ointment, consult a dermatologist.
Hair Loss.	Scalp, eyebrows, eyelashes.	Practice habit-reversal training with a mental health professional.
Dental Wear.	Teeth and jaw joints.	Visit your dentist for a protective night guard.

• Scarring: Repeated trauma to skin tissue often results in permanent scars or uneven pigmentation.

When these actions alter your natural appearance, they can profoundly affect your mood, self-esteem, and daily confidence. Working with a mental health counselor can help you process and manage these emotional impacts effectively.

How Are BFRBs Diagnosed?

Often, your primary care doctor, a dermatologist, or your dentist will be the first doctor to notice signs of a BFRB. For example, if you visit a dermatologist for a skin rash, they might recognize that the underlying cause involves repetitive skin picking.

Your doctor will ask you detailed questions about your physical symptoms and how you feel emotionally. They may then refer you to a mental health specialist, such as a psychiatrist or a psychologist, for a thorough evaluation.

A mental health professional will review your symptoms against clinical diagnostic criteria to confirm whether you have a BFRB:

• You engage in repetitive physical behaviors that cause damage to your body.
• You repeatedly try to stop or reduce these behaviors without success.
• The behaviors cause significant emotional distress or interfere with your daily life and responsibilities.

What Treatments Are Available for BFRBs?

Treatments for body-focused repetitive behaviors often combine counseling, behavioral therapies, and sometimes medicine:

• Counseling and Therapy: A mental health counselor can guide you through cognitive behavioral therapy, teaching you a specific approach called habit-reversal training. This helps you gain deep awareness of the triggers that start the behavior. You also learn to replace the habit with a safe alternative response. For example, whenever you feel the urge to pick your skin, you can practice squeezing a stress ball or holding a smooth worry stone instead.
• medicines: The U.S. Food and Drug Administration has not approved a medicine specifically dedicated to treating BFRBs. However, doctors can prescribe certain medicines to help manage related symptoms and reduce anxiety. A doctor may suggest selective serotonin reuptake inhibitors, which are common antidepressant medicines. also, dietary supplements like N-acetylcysteine have proven helpful for some people.

What Is the Patient Experience Like with BFRBs?

Living with a BFRB feels different for everyone. You might experience waves of restlessness, brief physical relief, or intense emotional distress. It is often hard to predict exactly when the urge to pick or pull will strike, and you may find yourself performing the action without even realizing it.

Over time, these behaviors can cause physical marks, skin scars, or hair thinning. However, you do not have to navigate this alone. Professional treatments, especially a combination of counseling and supportive care, help you manage BFRB symptoms effectively.

Realize that recovery takes time and consistent practice—these habits do not disappear overnight. If you ever have questions about your treatment plan, talk openly with your healthcare team.

When Should You See a Doctor?

You should schedule an appointment with a doctor if you experience repetitive body-focused behaviors that you want to stop but cannot manage on your own. This includes chronic skin picking, teeth grinding, or hair pulling.

also, seek medical care right away if any skin wound or sore shows signs of a bacterial infection, such as increasing pain, severe swelling, warmth, or pus drainage.

What Questions Should You Ask Your Doctor?

When you visit your doctor or mental health specialist, consider asking these helpful questions:

• How can I best stop or manage my BFRB symptoms?
• Should I talk with a mental health counselor or behavioral therapist?
• Do you recommend any specific medicines or supplements?
• What potential side effects should I watch out for if I take medicine?

The Takeaway Message.

Nobody wants to feel like they cannot control their own actions. No matter how many times you have tried to stop and felt like nothing works, you are not alone. That frustration is a very real part of living with a body-focused repetitive behavior.

The encouraging news is that you do not have to struggle with these habits forever. A qualified doctor can help you find an effective path forward. Many people successfully manage their symptoms using therapy, counseling, or medicine.

It may take a few months of practice and patience before you notice lasting results. Your medical care team will support you in managing your BFRB for the long term. Never feel ashamed to ask for help, because reaching out is the bravest step toward healing.
