« Back to Glossary Index

Trichotillomania, often referred to as hair-pulling disorder, is a mental health condition characterized by a recurrent and irresistible urge to pull out hair from one’s scalp, eyebrows, eyelashes, or other body areas. This behavior is typically driven by underlying psychological factors such as stress, anxiety, or a need for relief from tension, and it can lead to significant emotional distress and functional impairment. The onset of trichotillomania usually occurs in early adolescence and can persist into adulthood, often co-occurring with other conditions like depression, anxiety, and obsessive-compulsive disorder (OCD). Despite the chronic nature of the disorder, effective treatments, including cognitive-behavioral therapy (CBT) and certain medications, can help manage symptoms and improve quality of life for those affected​ (Cleveland Clinic)​​ (Mayo Clinic)​​ (​​ (Theravive)​​ (ABCT)​.

Prevalence and Demographics

Trichotillomania (TTM) is a condition that primarily affects females, with a marked predominance in this group compared to males. Studies have shown that approximately 1-2% of the general population suffers from TTM, with a significantly higher prevalence in women, making up about 80-90% of those affected. The typical onset of TTM occurs during early adolescence, with many individuals reporting the beginning of hair-pulling behaviors between the ages of 10 and 13. This early onset highlights the importance of early detection and intervention to manage the disorder effectively.

Demographically, TTM does not appear to discriminate based on race or ethnicity, as it is found across various demographic groups. However, most studies, including a comprehensive one that analyzed a sample with a mean age of 30.1 years, reported a high prevalence among White Caucasian participants, which could reflect sampling biases or healthcare access disparities. The disorder often coexists with other psychiatric conditions, such as anxiety, depression, and obsessive-compulsive disorder (OCD), complicating the clinical picture and necessitating a comprehensive treatment approach​ (1)​​ (2)​.

Symptoms and Diagnosis

Trichotillomania (TTM), also known as hair-pulling disorder, is characterized by the recurrent, compulsive urge to pull out one’s hair, resulting in noticeable hair loss. Individuals with TTM may pull hair from various parts of their body, but the most common areas include the scalp, eyebrows, and eyelashes.

Key symptoms of TTM include:

Diagnostic Criteria

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), provides specific criteria for diagnosing TTM:

  1. Recurrent pulling out of one’s hair, resulting in hair loss.
  2. Repeated attempts to decrease or stop hair pulling.
  3. The hair pulling causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.
  4. The hair pulling or hair loss is not attributable to another medical condition (e.g., a dermatological condition).
  5. The hair pulling is not better explained by the symptoms of another mental disorder (e.g., attempts to improve a perceived defect or flaw in appearance in body dysmorphic disorder).

Comorbid Conditions

TTM is often associated with other psychiatric disorders, which can complicate its diagnosis and treatment. Common comorbid conditions include:

Behavioral Indicators

Behavioral indicators of TTM include:

Case Studies and Clinical Observations

Several studies have documented the behavioral patterns and psychological impact of TTM. For instance, a study published in CNS Spectrums highlighted that TTM often coexists with anxiety and depression, and that individuals with TTM experience significant impairment in their quality of life​ (Cambridge)​ (Mayo Clinic) (3).

Psychological and Neurological Perspectives

Psychological Factors

Neurological Insights

  1. Brain Structure and Function Neuroimaging studies have provided insights into the brain structure and function of individuals with TTM. Abnormalities in the brain regions associated with habit formation, impulse control, and emotional regulation have been identified. Specifically, differences in the anterior cingulate cortex (ACC) and the basal ganglia, which are involved in the regulation of habitual behaviors and emotions, have been noted. These brain regions show altered activity patterns in people with TTM, suggesting a neurological basis for the disorder​ (Cambridge)​​ (Cambridge)​.
  2. Genetic Factors There is evidence to suggest a genetic component to TTM. Studies have shown that first-degree relatives of individuals with TTM are more likely to exhibit similar body-focused repetitive behaviors, indicating a hereditary predisposition. Genetic studies are ongoing to identify specific genes that may contribute to the development of TTM​ (2)​.
  3. Neurotransmitter Imbalances Imbalances in neurotransmitters, particularly serotonin and dopamine, have been implicated in TTM. These neurotransmitters play crucial roles in mood regulation and the reward system of the brain. Medications that affect serotonin levels, such as selective serotonin reuptake inhibitors (SSRIs), have been used to treat TTM, further supporting the involvement of neurotransmitter dysregulation in the disorder​ (Cambridge)​.

Integrative Models

Treatment Approaches

Behavioral Interventions

Habit Reversal Training (HRT) Habit Reversal Training (HRT) is one of the most effective behavioral interventions for Trichotillomania (TTM). HRT consists of several components:

Cognitive Behavioral Therapy (CBT) CBT is another widely used approach for treating TTM. It helps individuals identify and change dysfunctional thoughts and behaviors that contribute to hair-pulling. Key components include:

Pharmacological Treatments

Emerging Treatments

Impact on Quality of Life

Psychosocial Impact

Occupational and Academic Challenges

Physical Health Consequences

Case Studies and Personal Stories


In conclusion, trichotillomania significantly impacts the quality of life, affecting emotional well-being, social relationships, and physical health. The disorder often leads to emotional distress, social isolation, and difficulties in personal and professional domains due to the compulsive nature of hair-pulling and the resulting visible hair loss. The chronic nature of TTM can result in serious dermatological issues and, in severe cases, medical complications like trichobezoars. Understanding these diverse impacts underscores the importance of a comprehensive, multidisciplinary approach to treatment, incorporating both psychological therapies and medical interventions to improve the overall quality of life for individuals with TTM.
