What is the prevalence of Trichotillomania?

How many people does Trichotillomania affect? Does it have the same prevalence in men and women? And in the different countries?


Trichotillomania is a psychiatric disorder characterized by the recurrent pulling out of one's own hair, resulting in noticeable hair loss. It is considered a chronic condition that often begins in childhood or adolescence and can persist into adulthood. The exact prevalence of trichotillomania is difficult to determine due to underreporting and misdiagnosis, but studies suggest that it affects approximately 1-2% of the population.


Trichotillomania is more common in females than males, with a female-to-male ratio of about 3:1. It can have a significant impact on an individual's quality of life, causing distress, social impairment, and functional impairment. The disorder is often associated with other psychiatric conditions such as anxiety disorders, depression, and obsessive-compulsive disorder.


Early detection and intervention are crucial in managing trichotillomania. Treatment options include cognitive-behavioral therapy (CBT), habit reversal training, medication, and support groups. CBT, in particular, has shown promising results in helping individuals gain control over their hair-pulling behaviors.


It is important to raise awareness about trichotillomania and provide support for those affected by the disorder. With proper understanding and treatment, individuals with trichotillomania can lead fulfilling lives.

I've heard about 1 in 100. That wouldn't be all extreme cases though. People with severe trich who pull from their scalp would have to resort to covering their natural hair - or lack of, with wigs or scarves or shaving, because there just isn't hair left on the scalp for covering the loss up. The same with those with severe eyelash or brow trich - the loss would be obvious.

Trichotillomania is estimated to affect one to four percent of people. However, people afflicted by Trich often hide their disorder by any means necessary, but the disorder is much more prevalent than the medical community, or those afflicted for that matter, may realise, simply by the nature of this disorder.

ONSET IS EARLY CHILDHOOD AND IT CAN AFFECT BOTH WOMEN AND MEN BUT MOSTLY WOMEN As many as 4 percent of people may have trichotillomania, according to the National Institutes of Health, and the condition is four times more common among women. The disorder is usually first seen before people reach age 17. Trichotillomania(TTM)Awareness and other Facebook groups were created to help encourage others suffering the same.

Trichotillomania occurs in roughly 0.6-4% of the world population, and roughly 1% in the U.S., or ~2.5 million people. More than half (anywhere between 70-93%) of those affected are women.

I am not sure of trich specifically, but 1 in 25 people live with body-focused repetitive behaviours, which is what trich is. There is a higher prevalence in women for all bfrbs, but this could be skewed because men aren't so readily welcoming of seeking treatment.

Trichotillomania may be more common than we think because most people don't seek help and keep it away from people but it's still not that common. It's more common in women than men. Trichotillomania is 7 times as prevalent in children as in adults, with the peak prevalence between the ages of 4 and 17 years.
