What is the primary characteristic of trichotillomania?

The primary characteristic of trichotillomania is the recurrent pulling out of one's hair. This is classified as a mental health disorder, specifically within the category of obsessive-compulsive and related disorders. Individuals with trichotillomania experience an irresistible urge to pull hair from various parts of their body, such as the scalp, eyebrows, and eyelashes, which can lead to noticeable hair loss and significant distress.

This behavior is often accompanied by a sense of tension before pulling or trying to resist the behavior, and a sense of relief or gratification once the hair is pulled. Understanding this primary characteristic is crucial for recognizing the disorder and guiding appropriate interventions or treatment options.
