Trichotillomania (TTM) is a type of impulse control disorder in which people with an irresistible urge to pull their hair out, and although they realize the harm they are causing themselves, often cannot control this urge.

TTM has been documented in medical studies since the 0.5th century, and community prevalence studies indicate that it is a common disorder with a point prevalence of about 2.0% to 4% in adults, in addition to being more common in females than males (1:XNUMX female: male). Childhood It was found that the sex distribution is equal.

TTM patients often have co-occurring disorders, such as nail biting (onychophagia) or skin peeling disorder.
