What is Trichotillomania

Trichotillomania, also known as hair-pulling disorder, is a body-focused repetitive behavior characterized by the recurrent, irresistible urge to pull out hair from the scalp, eyebrows, or other areas of the body, despite attempts to stop. It is classified as a condition related to obsessive-compulsive disorder and can have significant impacts on a person’s emotional well-being and physical health.

What body systems are affected by Trichotillomania?

While Trichotillomania is primarily a psychological condition, it affects multiple body systems. The integumentary system (skin and hair) is the most visibly affected, often resulting in hair loss, skin irritation, or infections. When individuals ingest the pulled hair, it can impact the digestive system, potentially leading to gastrointestinal blockages or the formation of trichobezoars (hairballs). Furthermore, chronic stress associated with the disorder can affect the immune system, potentially increasing vulnerability to illness.

Who is typically affected by Trichotillomania?

Trichotillomania typically has an age of onset during late childhood or early adolescence, usually between the ages of 10 and 13. While it can affect anyone, research indicates a female predominance in clinical settings. Prevalence rates are estimated to be between 1% and 2% of the general population. Within the DiseaseMaps community, 529 people with Trichotillomania have shared their experiences, highlighting the importance of peer support for this often-isolated condition.

How does Trichotillomania differ from other conditions?

It is important to distinguish Trichotillomania from other hair-loss conditions like alopecia areata. Key clinical features include:

• The Urge-Relief Cycle: Pulling is often preceded by mounting tension and followed by a sense of relief or gratification.


• Emotional Triggers: Episodes are frequently linked to feelings of anxiety, depression, boredom, or hopelessness.


• Intentionality: Unlike autoimmune hair loss, the hair loss in Trichotillomania is the direct result of self-directed physical action.

Next steps

• Consult a psychiatrist or psychologist specializing in Habit Reversal Training (HRT) and Cognitive Behavioral Therapy (CBT).


• Discuss potential adjunctive therapies, such as N-acetylcysteine (NAC), with your doctor, as some studies suggest it may decrease urges by up to 40%.


• Connect with the 529 members of the DiseaseMaps.org community to share experiences and coping strategies.
