Trichotillomania: Symptoms, Diagnosis & Treatment

Trichotillomania (pronounced trick-oh-till-oh-MAY-nee-uh), commonly known as hair-pulling disorder, is a mental health condition characterized by the repetitive, compulsive urge to pull out one’s own hair. This condition affects millions of people worldwide and can have profound impacts on both physical appearance and emotional well-being.

The term trichotillomania comes from three Greek words: “tricho” meaning hair, “tillein” meaning to pull, and “mania” meaning madness or frenzy. While the condition was first documented in ancient Greece, the modern name was coined in the late 18th century by French dermatologist François Henri Hallopeau in 1889.

What Is Trichotillomania?

Trichotillomania is classified as an obsessive-compulsive and related disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). People with this condition experience irresistible urges to pull out hair from their scalp, eyebrows, eyelashes, or other areas of their body, despite repeated attempts to stop or reduce the behavior.

The disorder is part of a group of conditions known as body-focused repetitive behaviors (BFRBs), which include skin picking (excoriation disorder), nail biting, and lip biting. Unlike simple nervous habits, trichotillomania involves significant distress and functional impairment that interferes with daily life activities.

Signs and Symptoms

Physical Signs

The most obvious sign of trichotillomania is noticeable hair loss, which can present in various patterns:

Hair Loss Patterns:

• Patchy bald spots on the scalp with an unusual, asymmetrical shape
• Shortened hair of varying lengths in affected areas
• Thinned or completely missing eyebrows or eyelashes
• Sparse body hair in areas like arms, legs, or pubic region
• The “Friar Tuck sign” – hair loss at the crown while maintaining hair in temporal and occipital regions

Additional Physical Symptoms:

• Hair of different lengths and stages of regrowth in affected areas
• Geometric or well-defined areas of hair loss
• Skin irritation, infections, or scarring in areas of repeated pulling
• Damaged hair follicles that may lead to permanent hair loss if untreated

Behavioral and Emotional Symptoms

Pulling Behaviors:

• Repetitive hair pulling that may last from seconds to hours
• Specific rituals around hair selection and pulling techniques
• Searching for particular types of hair (coarse, curly, or “different” feeling)
• Using tools like tweezers, needles, or bobby pins to aid in pulling
• Playing with, examining, or manipulating pulled hair
• Biting, chewing, or eating pulled hair (trichophagia) – occurs in approximately 20% of cases

Emotional and Psychological Symptoms:

• Increasing tension or anxiety before pulling
• Sense of relief, pleasure, or gratification during or after pulling
• Feelings of shame, embarrassment, or guilt about the behavior
• Attempts to hide hair loss with wigs, makeup, hats, or strategic styling
• Avoidance of social situations, intimacy, or activities that might expose hair loss
• Depression, anxiety, or low self-esteem related to appearance

Types of Hair-Pulling Episodes

Researchers have identified two distinct styles of hair pulling:

Automatic Pulling:

• Occurs outside of conscious awareness
• Often happens during sedentary activities like reading, watching TV, or driving
• Person may not realize they’re pulling until after the episode
• Can happen during states of boredom, relaxation, or concentration

Focused Pulling:

• Deliberate and conscious hair pulling
• Often triggered by negative emotions like stress, anxiety, sadness, or frustration
• May involve specific rituals or techniques
• Person is fully aware of the behavior and may have difficulty stopping

Many people with trichotillomania experience both types of pulling at different times.

Causes and Risk Factors

The exact cause of trichotillomania remains unclear, but research suggests it results from a complex interaction of genetic, neurobiological, psychological, and environmental factors.

Genetic Factors

Studies indicate that trichotillomania may have a hereditary component. People with a first-degree relative (parent or sibling) who has trichotillomania are more likely to develop the condition themselves. Twin studies have demonstrated genetic anomalies associated with trichotillomania and other obsessive-compulsive related disorders.

Neurobiological Factors

Brain Structure and Function: Research using neuroimaging has revealed several brain abnormalities in people with trichotillomania:

• Thickening of the right inferior frontal gyrus
• Reduced cerebellar volumes
• Reduced integrity of white matter tracts in areas responsible for impulse control
• Abnormalities in the frontostriatal-thalamic pathway
• Higher cerebral glucose metabolic rates in the cerebellum and right parietal cortex

Neurotransmitter Systems: Multiple neurotransmitter systems appear to be involved:

• Serotonin system abnormalities, particularly involving serotonin 2A receptors
• Dopamine system involvement, evidenced by positive responses to certain antipsychotic medications
• Glutamate system dysfunction, supported by the effectiveness of glutamate-modulating agents

Psychological Factors

Emotional Regulation: Many people with trichotillomania report that hair pulling serves as a way to:

• Manage stress, anxiety, or negative emotions
• Provide sensory stimulation or satisfaction
• Create a sense of control during overwhelming situations
• Achieve a state of calm or focused attention

Perfectionism: Recent research has identified perfectionism as a significant factor in trichotillomania. People with the condition often exhibit:

• Overly critical self-evaluation
• Difficulty tolerating imperfection in their appearance or environment
• Rigid thinking patterns about how things “should” be
• Use of hair pulling as a response to perfectionistic frustration

Environmental Triggers

Stress and Trauma: While stress doesn’t cause trichotillomania, it can trigger or worsen symptoms. Common triggers include:

• Major life changes or transitions
• Academic or work pressure
• Relationship difficulties
• Childhood trauma or adverse experiences
• Hormonal changes during puberty or menstruation

Environmental Factors:

• Boredom or lack of stimulation
• Isolation or privacy that allows for uninterrupted pulling
• Specific settings or activities that have become associated with pulling
• Accessibility to pulling tools or triggers

Demographics and Prevalence

Age and Onset

Trichotillomania typically begins during adolescence, with the most common age of onset between 10 and 13 years old. However, the condition can develop at any age:

Childhood (Before Age 6):

• Often presents as a self-soothing behavior
• Usually mild and may resolve on its own within 12 months
• Occurs equally in boys and girls

Adolescence and Adulthood:

• More severe and chronic form of the condition
• Often persists throughout life without treatment
• Associated with greater psychological distress and functional impairment

Gender Distribution

The gender distribution of trichotillomania varies by age:

• Childhood: Equal occurrence in boys and girls
• Adolescence and Adulthood: Significant female predominance, with women being 4-10 times more likely to be affected
• Treatment-seeking: Women are more likely to seek medical help, which may contribute to higher reported rates

Prevalence Rates

Research suggests that trichotillomania is more common than previously thought:

• Lifetime prevalence: Estimated at 0.5% to 3.4% of adults
• Point prevalence: 0.5% to 2.0% of the population at any given time
• Adolescent rates: Up to 3.5% may experience some form of hair-pulling behavior
• Underreporting: The actual prevalence may be higher due to shame and secrecy surrounding the condition

Diagnosis

Diagnostic Criteria

According to the DSM-5, a diagnosis of trichotillomania requires meeting five specific criteria:

Criterion A: Recurrent pulling out of one’s hair, resulting in hair loss

Criterion B: Repeated attempts to decrease or stop hair pulling

Criterion C: The hair pulling causes clinically significant distress or impairment in social, occupational, or other important areas of functioning

Criterion D: The hair pulling or hair loss is not attributable to another medical condition (such as a dermatological condition)

Criterion E: The hair pulling is not better explained by the symptoms of another mental disorder

Diagnostic Process

Clinical Interview: A thorough diagnostic evaluation typically includes:

• Detailed history of hair-pulling behaviors
• Assessment of triggers and consequences
• Evaluation of functional impairment
• Screening for co-occurring mental health conditions
• Family history of similar conditions

Physical Examination: Healthcare providers will examine:

• Areas of hair loss for characteristic patterns
• Skin condition and signs of scarring
• Evidence of hair regrowth at different stages
• Overall hair and scalp health

Specialized Tests: In some cases, additional testing may be helpful:

• Punch biopsy: Can confirm traumatic hair removal and rule out other causes of hair loss
• Dermoscopy/Trichoscopy: Specialized examination of hair and scalp that can reveal characteristic signs of trichotillomania
• Photography: Documentation of hair loss patterns to track treatment progress

Assessment Tools

Several standardized scales help clinicians assess trichotillomania severity:

• National Institute of Mental Health Trichotillomania Severity Scale (NIMH-TSS)
• Massachusetts General Hospital Hairpulling Scale (MGH-HPS)
• Milwaukee Inventory for Styles of Trichotillomania (MIST)
• Trichotillomania Scale for Children

Differential Diagnosis

Healthcare providers must distinguish trichotillomania from other conditions that cause hair loss:

Medical Conditions:

• Alopecia areata (autoimmune hair loss)
• Tinea capitis (fungal scalp infection)
• Androgenetic alopecia (male/female pattern baldness)

Treatment Options

Effective treatment for trichotillomania typically involves a combination of psychological interventions, medications, and supportive strategies. Treatment should be individualized based on the person’s age, severity of symptoms, and specific needs.

Psychological Treatments

Habit Reversal Training (HRT): Considered the gold standard for trichotillomania treatment, HRT involves three main components:

Awareness Training:

• Learning to recognize urges and triggers
• Identifying situations and emotions that lead to pulling
• Developing mindfulness of pulling behaviors

Competing Response Training:

• Learning alternative behaviors to replace hair pulling
• Practicing responses like clenching fists, sitting on hands, or holding a stress ball
• Engaging in activities that make pulling difficult

Social Support:

• Involving family members or friends in treatment
• Getting encouragement for using alternative behaviors
• Creating accountability systems

Cognitive Behavioral Therapy (CBT): CBT helps people identify and change thought patterns that contribute to hair pulling:

• Challenging perfectionistic beliefs
• Developing healthy coping strategies for stress and emotions
• Addressing cognitive distortions about appearance
• Building self-esteem and confidence

Acceptance and Commitment Therapy (ACT): ACT focuses on accepting difficult emotions while committing to valued actions:

• Learning to tolerate urges without acting on them
• Identifying personal values and meaningful activities
• Developing psychological flexibility
• Mindfulness and acceptance strategies

Dialectical Behavior Therapy (DBT): DBT teaches skills for managing intense emotions:

• Distress tolerance techniques
• Emotion regulation strategies
• Interpersonal effectiveness skills
• Mindfulness practices

Pharmacological Treatments
