It seems trichotillomania has a strong genetic component after a study confirmed a certain gene mutation predicted the disorder in families.
Trichotillomania, the mental health condition that involves people pulling out hairs from various locations on the body, can add significant distress to a person’s life. In a search to better understand and treat the condition, experts hope to find the source of trichotillomania and its symptoms.
Some combination of environmental and biological factors tend to influence the presence ofmental health disorders, including trichotillomania. By identifying trichotillomania as a genetic disease or an environmental disorder, people can better prevent and treat the condition.
Trichotillomania Research
To learn if a condition develops because of genetic or environmental influences, scientists and mental health experts must perform a variety of experiments to pinpoint factors that cause trichotillomania to present in some people but not others. Depending on the goals and basis of the investigation, the research may study people with trichotillomania, perform testing on their family members or both.
Much of trichotillomania research centers around one specific gene called SLITKR1. Researchers showed interest in this gene because previous studies have linked it to similar mental health conditions that also involve repetitive and uncontrollable behaviors, like Tourette’s syndrome.

Onestudyinvestigated 44 families where at least one member had trichotillomania to look for common genetic traits. The study found that the SLITK1 gene was mutated (abnormal) in the family members with the condition, but not in the family members without trichotillomania.
This evidence shows a definite connection between genetic differences and the onset of trichotillomania in people studied.
Is Trichotillomania Inherited?
Based on the findings of this study, one can conclude there is clear proof showingtrichotillomaniais an inherited mental health condition. However, there is more to the story.
Researchers believe mutations of the SLITRK1 gene only account for about5 percentof all existing cases of trichotillomania. This result could mean that other genes factor into the development of the condition, or that additional environmental and biological risk factors also play a significant role in the emergence of trichotillomania.
People with high levels of stress and tension are more prone to hair-pulling disorder as a way to cope with uncomfortable feelings.Brain scansshow that people with trichotillomania have small differences in some areas of the brain compared to people without the disorder, which suggests that brain development abnormalities could play a role in the condition’s development.
So, is trichotillomania inherited? Yes, it can be, but other factors also contribute to the condition. As research and studies continue, understanding of the causes of trichotillomania and other mental health disorders will increase and improve prevention and treatment options.
