In moments of stress or boredom, you may find yourself unconsciously touching your hair, biting your nails, or repeatedly picking at your skin. These habits may seem harmless or temporary, but in some cases they can develop into compulsive behaviors that are difficult to control and may interfere with daily life.This phenomenon is known as Body-Focused Repetitive Behaviors (BFRBs), a group of repetitive actions directed toward one's own body. These behaviors are often associated with stress, anxiety, or even absent-mindedness.Although many people engage in these behaviors to a mild degree, they can become a significant problem when they lead to physical harm, feelings of embarrassment, or a sense of losing control. In this Dalili Medical article, we will explore what BFRBs are, why they occur, and how they can be managed and reduced through effective strategies.

What Are Body-Focused Repetitive Behaviors (BFRBs)?

Body-Focused Repetitive Behaviors (BFRBs) are a group of psychological disorders characterized by repetitive actions directed toward one's own body, such as nail biting, lip biting, cheek chewing, skin picking, scab removal, and hair pulling.

Research suggests that a significant number of individuals engage in one or more of these behaviors to varying degrees. Nail biting is among the most common forms, while skin picking is less common but can cause more significant physical harm.

These behaviors are often associated with elevated levels of stress or anxiety. In some cases, they may serve as an unconscious way of regulating emotions, obtaining temporary relief, or seeking sensory stimulation.

People frequently engage in these behaviors during periods of psychological stress or tension, and they may become habitual when repeated regularly, particularly if they occur several times per week. When the behaviors become severe enough to interfere with daily life or cause physical injury, consultation with a mental health professional is recommended.

Many individuals with BFRBs report experiencing temporary relief or satisfaction while performing the behavior, despite recognizing its harmful effects and wanting to stop. These conditions are often linked to difficulties with impulse control, making it challenging to discontinue the behavior without appropriate treatment.

Is It a Serious Mental Illness?

BFRBs are not inherently dangerous, but they can become problematic if they:

• Cause wounds or physical injury

• Interfere with daily, social, or occupational functioning

• Lead to psychological distress or feelings of embarrassment

Is It a Habit or a Disorder?

• If the behavior is mild and easily controlled, it is generally considered a behavioral habit.

• If it is repetitive, difficult to control, and causes harm or distress, it may be classified as a mental health disorder.

Can It Go Away on Its Own?

In some cases, symptoms may decrease over time. However, most individuals benefit from:

• Increased awareness of the behavior

• Training in self-control and behavior management techniques

• Psychological treatment in more severe cases

Is It Contagious?

No. BFRBs are not contagious. They are individual behaviors related to habits, emotional regulation, and brain function.

Does It Indicate Weak Character?

Absolutely not. BFRBs are associated with:

• The brain's mechanisms for regulating stress and emotions

• Impulsivity and behavioral habits

They are not a sign of weak willpower or poor character.

Types of Body-Focused Repetitive Behaviors (BFRBs)

BFRBs are not a single condition but rather a group of compulsive behaviors that vary depending on the body part involved and the nature of the behavior.

1. Hair Pulling

This behavior involves pulling hair from the scalp, eyebrows, eyelashes, or other areas of the body.

It may occur intentionally or automatically, such as searching for a specific hair or pulling during periods of stress or concentration.

Medical term: Trichotillomania

2. Skin Picking or Scab Picking

This includes repeatedly scratching, picking, squeezing, or removing skin and scabs.

Individuals may focus on pimples, dry skin, or minor imperfections, sometimes leading to wounds or scarring.

Medical term: Excoriation Disorder (Skin-Picking Disorder)

3. Nail Biting

This involves repeatedly biting the fingernails or the surrounding skin.

It is one of the most common BFRBs and often increases during periods of stress or boredom. In some cases, it can cause nail deformities or infections.

4. Lip or Cheek Biting

This behavior involves repeatedly biting the lips or the inside of the cheeks, often unconsciously during thinking, concentration, or stress.

5. Repetitive Touching of Skin or Hair

This includes repeatedly touching, rubbing, inspecting, or manipulating the skin or hair without necessarily removing it.

Such behaviors may sometimes precede more severe actions like hair pulling or skin picking.

6. Less Common Behaviors

Other less common BFRBs include:

• Picking at the skin around the nails

• Mild eyebrow or eyelash pulling

• Compulsive nose picking in some cases

Causes and Symptoms of Body-Focused Repetitive Behaviors (BFRBs)

Body-Focused Repetitive Behaviors (BFRBs) are repetitive, automatic, or compulsive actions directed toward one's own body, such as hair pulling, nail biting, or skin picking. These behaviors are typically influenced by a combination of psychological, behavioral, and neurological factors rather than a single cause.

Causes of BFRBs

1. Stress and Anxiety

Psychological stress and anxiety are among the most common triggers. Many individuals engage in these behaviors as an unconscious method of relieving emotional tension or negative feelings.

2. Habit Formation and Self-Regulation

Over time, the brain may learn that these behaviors provide temporary relief or satisfaction, leading them to become automatic habits, especially during boredom, concentration, or daydreaming.

3. Impulsivity and Difficulty Controlling Behavior

Some individuals experience difficulty resisting urges, causing them to engage in the behavior despite their desire to stop.

4. Neurological Factors

BFRBs are thought to involve the brain's reward pathways, including dopamine-related mechanisms, which can create a temporary sense of relief despite negative long-term consequences.

5. Co-Occurring Mental Health Conditions

These behaviors may occur alongside other psychological conditions, such as anxiety disorders or obsessive-compulsive disorder (OCD).

Examples include:

• Trichotillomania (Hair-Pulling Disorder)

• Excoriation Disorder (Skin-Picking Disorder)

6. Environmental Influences and Learned Habits

A behavior may begin as a simple, unnoticed habit—such as touching the hair or skin—and gradually develop into a repetitive pattern that becomes difficult to control.

Symptoms of BFRBs

Symptoms vary from person to person but commonly include:

1. Repetitive Behaviors That Are Difficult to Control

• Repeated hair pulling, nail biting, or skin picking

• Multiple unsuccessful attempts to stop

2. Loss of Control and Compulsive Urges

• Strong and sudden urges to perform the behavior

• Automatic engagement in the behavior, especially during stress or concentration

3. Temporary Relief

• A sense of calm, satisfaction, or reduced tension while performing the behavior

• Often followed by guilt, frustration, or regret

4. Visible Physical Effects

• Hair loss or bald patches on the scalp

• Skin wounds, irritation, or scarring

• Cracked, damaged, or deformed nails

5. Association With Specific Situations

The behavior often increases during:

• Stress or anxiety

• Boredom

• Periods of intense concentration

• Daydreaming or mind-wandering

6. Psychological and Social Impact

• Feelings of guilt or embarrassment after engaging in the behavior

• Attempts to hide the physical effects from others

Diagnosis of Body-Focused Repetitive Behaviors (BFRBs)

The diagnosis of Body-Focused Repetitive Behaviors (BFRBs) is not based solely on the presence of a repetitive habit. Rather, it requires a careful evaluation by a mental health professional using specific criteria that distinguish normal habits from a psychological disorder.

1. Primary Diagnostic Disorders

The two most widely recognized medical diagnoses in this category are:

• Trichotillomania (Hair-Pulling Disorder)

• Excoriation Disorder (Skin-Picking Disorder)

2. General Diagnostic Criteria (Simplified From DSM-5)

A diagnosis is typically considered when the following are present:

A. Repetitive Behavior That Is Difficult to Control

• Recurrent hair pulling, skin picking, or nail biting

• Repeated attempts to stop with little or no lasting success

B. Negative Impact on Daily Life

• Significant emotional distress, embarrassment, or guilt

• Interference with school, work, or social relationships

C. Physical Harm or Significant Time Consumption

• Hair loss, skin damage, wounds, or nail deterioration

• Spending excessive amounts of time engaging in the behavior

D. Exclusion of Other Medical Causes

• The behavior is not better explained by a skin condition, neurological disorder, or another medical condition

3. Distinguishing a Habit From a Disorder

Not every body-focused repetitive behavior is considered a mental disorder.

It is generally classified as a disorder when it:

• Becomes repeatedly uncontrollable

• Causes noticeable physical harm

• Leads to significant psychological or social distress

4. Practical Diagnostic Process

Diagnosis is usually made through:

• A clinical interview with a psychiatrist or psychologist

• Assessment of the frequency and triggers of the behavior

• Evaluation of associated emotions such as stress, boredom, or anxiety

• The use of behavioral questionnaires or assessment scales when needed

Risks of Body-Focused Repetitive Behaviors (BFRBs)

The risks vary depending on the specific behavior, but they can affect physical, psychological, and social well-being and may worsen over time if left untreated.

1. Physical Risks

A. Damage to the Skin and Hair

• Hair loss or bald patches on the scalp

• Wounds, scratches, or chronic skin irritation

• Scarring or permanent skin changes

This includes disorders such as:

• Trichotillomania

• Excoriation Disorder

B. Infections

• Bacteria entering through open wounds

• Recurrent skin infections

• Worsening of the condition when treatment is delayed

C. Mouth and Nail Problems

• Cracked, damaged, or worn nails

• Pain or dental and gum problems from lip or cheek biting

• Chronic irritation in affected areas

2. Psychological Risks

• Increased feelings of guilt or embarrassment

• Reduced self-esteem due to appearance changes or physical damage

• Ongoing anxiety about hiding the behavior or controlling it

• A repeating cycle of:
  Stress → Behavior → Temporary Relief → Guilt → More Stress

3. Social and Functional Risks

• Avoidance of social situations because of embarrassment

• Difficulty concentrating at school or work

• Reduced productivity due to time spent engaging in or thinking about the behavior

• Attempts to conceal physical signs from others

4. Potential for Worsening Over Time

Without appropriate intervention, the behavior may:

• Become more frequent

• Increase in severity

• Progress from a simple habit to a clinically significant disorder requiring specialized treatment

Medication Treatment for Body-Focused Repetitive Behaviors (BFRBs)

Medication can be a helpful component of treatment for Body-Focused Repetitive Behaviors (BFRBs) in certain cases. However, it is generally not considered the first-line treatment. Behavioral approaches, particularly Habit Reversal Training (HRT), are typically preferred. Medications may be considered when symptoms are severe or when BFRBs occur alongside conditions such as anxiety, obsessive-compulsive disorder (OCD), or depression.

Important Note

Currently, there is no single medication specifically approved for all BFRBs. Instead, medications are used to target:

• Anxiety and stress

• Obsessive-compulsive symptoms

• Impulsivity and compulsive behaviors

• Serotonin and dopamine regulation in the brain

1. Selective Serotonin Reuptake Inhibitors (SSRIs)

Examples include:

• Fluoxetine

• Sertraline

• Paroxetine

How They Work

These medications help reduce anxiety and emotional distress while also decreasing obsessive thoughts that may trigger repetitive behaviors.

Effectiveness

• Results for BFRBs themselves are generally modest or variable.

• They may be particularly helpful when anxiety or OCD symptoms are also present.

2. N-Acetylcysteine (NAC)

N-Acetylcysteine is among the most extensively studied medications for BFRBs.

How It Works

• Influences glutamate regulation in the brain

• May reduce impulsive and repetitive behaviors

Potential Uses

Research suggests potential benefits for:

• Trichotillomania

• Excoriation Disorder

Effectiveness

• Some studies have shown improvement in a proportion of patients.

• However, it is not effective for everyone and should not be considered a guaranteed treatment.

3. Low-Dose Antipsychotic Medications

Examples include:

• Olanzapine

• Aripiprazole

How They Work

These medications affect dopamine pathways involved in reward and motivation, which may help reduce compulsive behaviors.

When They Are Used

They are generally reserved for:

• Severe cases

• Cases that do not respond to other treatments

and should only be used under close medical supervision.

4. Mood Stabilizers

Examples include:

• Lamotrigine (in selected cases)

• Valproate (rarely used)

These medications may occasionally be considered when emotional instability or additional psychiatric conditions contribute to the repetitive behaviors.

Role of Medication

These medications may help reduce impulsivity or mood instability in some patients. However, scientific evidence for their effectiveness in treating BFRBs is less strong compared to other treatment options.

5. Medications for Co-Occurring Anxiety

Examples include:

• Buspirone

• Certain mild tranquilizers (used with caution and for short periods only)

Goal:
To reduce anxiety and stress, which are among the main triggers of repetitive behaviors.

How Do Doctors Choose Medication?

The choice of treatment depends on several factors, including:

• The primary nature of symptoms (anxiety, obsessive thoughts, impulsivity)

• Severity of the behavior and its impact on daily life

• Presence of co-occurring mental health conditions

• Age and overall physical health

Treatment of Body-Focused Repetitive Behaviors (BFRBs)

Surgery – Exercises – and Alternative Treatments

Body-Focused Repetitive Behaviors (BFRBs) are behavioral disorders primarily driven by habits, impulsivity, and stress. Therefore, their treatment differs from that of traditional physical diseases.

---

First: Can BFRBs Be Treated with Surgery?

It is important to clarify that these behaviors are not treated with surgery in conventional psychiatric practice. There are no approved surgical procedures designed to stop behaviors such as hair pulling, nail biting, or skin picking.

❌ There is no direct surgery for BFRBs
There are:

• No brain regions surgically removed to eliminate the behavior

• No operations designed to remove compulsive urges

This is because these behaviors are not linked to a single, removable area of the brain.

---

Second: Are There Any Surgical-Like Interventions in Severe Cases?

In very rare and severe cases, neurosurgical or neuromodulation techniques may be used, but they are not direct treatments for BFRBs. They are mainly used for other disorders such as severe obsessive-compulsive disorder (OCD).

1. Deep Brain Stimulation (DBS)

This involves implanting electrodes in specific brain regions to modify neural activity related to compulsivity and impulsivity.

• Mainly used for severe, treatment-resistant OCD

• Some patients may experience indirect improvement in compulsive behaviors

• Not an approved direct treatment for BFRBs

• Considered only as a last resort after all other treatments fail

2. Psychosurgery (Rare Modern Use)

Such as:

• Cingulotomy

• Capsulotomy

Current status:

• Extremely rare today

• Used only in severe, treatment-resistant cases

• Performed under strict medical supervision

---

Third: Why Is Surgery Not Suitable for BFRBs?

Because these disorders:

• Are linked to learned behaviors and habits

• Are influenced by stress, anxiety, and environment

• Depend on impulsivity and emotional regulation

Therefore, they cannot be treated by removing a part of the brain. Instead, they require behavioral and psychological interventions.

---

Fourth: Effective Alternatives to Surgery

Scientific evidence shows that the most effective treatments include:

1. Behavioral Therapy (Most Important)

• Habit Reversal Training (HRT)

• Cognitive Behavioral Therapy (CBT)

2. Medication (When Needed)

• SSRIs (antidepressants)

• N-Acetylcysteine (in some cases)

---

Behavioral Exercise-Based Treatment (Practical Behavioral Therapy)

This approach focuses on retraining the brain to break the habit and replace it with alternative behaviors. It is considered one of the most effective methods.

1. Awareness Training

Goal: Increase awareness of the behavior before it happens automatically.

• Record when the behavior occurs

• Identify location and emotional triggers (stress, boredom, focus)

• Do this without trying to change the behavior at first

✔ This helps break unconscious behavior patterns.

---

2. Momentary Stop Exercise

Goal: Interrupt the automatic cycle.

When the urge begins:

• Pause for a few seconds

• Take a deep breath

• Repeat a mental phrase such as: “I am aware now”

✔ This creates awareness between urge and action.

---

3. Competing Response Training

This is the core technique.

Replace the behavior with an incompatible action:

• Hair pulling → clench fists or press hands on thighs

• Nail biting → hold a stress ball or place hands under thighs

• Skin picking → keep hands flat on a surface

✔ Continue for 1–3 minutes until the urge decreases.

---

4. Hand Distraction Exercise

Goal: Prevent idle hands.

Examples:

• Stress ball

• Beads or rosary

• Drawing or coloring

• Holding a pen or small object

---

5. Movement Change Exercise

Goal: Break environmental association.

• Change location immediately when urge appears

• Or walk for a few minutes

---

6. Urge Delay Training

Goal: Reduce urge intensity.

• Delay the behavior by 5 minutes

• Gradually increase the delay over time

✔ Urges often decrease naturally over time.

---

7. Deep Breathing Exercise

Goal: Reduce tension.

• Inhale for 4 seconds

• Hold for 2 seconds

• Exhale for 6 seconds

• Repeat 5 times

---

Suggested Daily Routine

• Morning: breathing + awareness

• During the day: use competing responses

• Evening: record observations

• Throughout the day: keep hands busy

---

When Does Improvement Occur?

• Mild cases: 1–2 weeks

• Moderate cases: 3–6 weeks

• Severe cases: require combined therapy with a mental health professional

---

Prevention of BFRBs

Prevention focuses on reducing triggers and building alternative habits that reduce the likelihood of the behavior occurring. The goal is gradual control, not forced suppression.

1. Reducing Triggers

• Avoid sitting in places where the behavior commonly occurs (e.g., bed during stress)

• Reduce prolonged mirror checking

• Improve lighting to reduce focus on skin imperfections

• Cover vulnerable areas when needed (e.g., hair ties, light gloves)

---

2. Keeping Hands Occupied

• Stress balls

• Pens or beads

• Drawing or coloring

• Using a phone stand to reduce face touching

---

3. Stress Reduction (Key Factor)

• Deep breathing exercises (4-2-6)

• Daily walking (10–20 minutes)

• Reducing caffeine intake

• Maintaining regular sleep

---

4. If–Then Planning

Pre-planned responses:

• If I touch my hair → I squeeze a stress ball

• If I start skin picking → I place my hands under my thighs or change location

✔ Helps interrupt automatic behavior.

---

5. Reducing Mental Idle Time

• Listening to podcasts or calming audio

• Engaging in light activities like drawing or reading

---

6. Physical Self-Care

• Regular nail trimming

• Treating skin issues (acne, dryness)

• Using moisturizers

---

7. Early Detection of Behavior

Early signs include:

• Repeated touching of the same area

• Frequent inspection of skin or hair

• Light pulling or scratching

✔ Intervene immediately with a competing response.

---

8. Reducing Overall Stress

• Organizing daily tasks

• Reducing academic or work pressure

• Scheduling daily relaxation time
