It involves the irresistible urge to pull out one’s hair from any area of the body including the scalp, eyebrows, eyelashes, and pubic area resulting in noticeable hair loss. If untreated, it is a chronic, though often intermittent condition. Pulling hair can result in visible bald patches, which can lead to significant distress and feelings of shame about the inability to stop this behavior. Urges increase at times of stress with individuals unaware that they are engaging in the hair pulling behavior.
Symptoms often start around puberty and occur more often in females. The disorder affects 4 in 100 people with an estimated 3-5 % lifetime prevalence. Some studies suggest that genetics play a role in the development of the disorder. Alternative theories propose that a stressful event such as abuse, family conflict, school difficulties, or death may trigger symptoms. People with trichotillomania may also have other disorders such as depression, OCD, or other anxiety disorders.
For many people with the disorder, hair pulling is a way of dealing with negative or uncomfortable feelings, such as stress, anxiety, or tension, loneliness, or frustration. It can also occur in relatively emotionally uneventful times such as when one is bored or relaxed (e.g. reading a book or watching a movie).
Some may intentionally make time to pull hair with a certain goal in mind, such as pulling out all gray hairs or hairs of a certain texture. Some people may develop rituals for pulling hair, such as playing with it in some way, biting pulled hair, rolling it between their fingers or lips, or swallowing the hair. Hair pulling may also be done without intent to pull the hair out but only for the satisfaction of feeling the texture of the hair. When the hair is pulled, people describe experiencing immediate feelings of gratification and relief. As a result, sufferers continue to pull their hair to maintain these positive feelings.
People with Trichotillomania experience significant distress and shame. Distress may include feeling a loss of control, embarrassment, or shame and impairment may occur due to avoidance of work, school, or other public situations. Some people with Trichotillomania also pick their skin, bite their nails, or chew their lips.
Due to noticeable hair loss, sufferers may endure negative comments from others resulting in feelings of negative self-worth and shame about their lack of impulse control.
People with Trichotillomania fear their disorder will be discovered and may go to great lengths to hide the disorder from others. They may pull their hair in private, wear wigs and style their hair to disguise bald patches or wear false eyelashes.
The avoidance can be socially debilitating. Trichotillomania sufferers may avoid intimacy, social activities, or even job opportunities due to embarrassment and fear of discovery and judgement. Some may experience depression, low self-esteem, or abuse substances due to hair pulling distress.
Trichotillomania typically impacts 1-4% of the population. Onset typically occurs in early adolescence. Prevalence of Trichotillomania is equal between genders. When tension release is excluded, females are two times more likely to be impacted than males.
Cognitive Behavioral Therapy is focused on understanding the function and patterns of the pulling behavior, awareness and tracking of hair pulling, learning new ways to regulate emotion, developing new physical habits, practicing physical relaxation techniques, and using environmental interventions such as removing tweezers, or utilizing Habit Reversal Training (HRT) technology (e.g. awareness bracelets) that alert the user to pulling movements, and other techniques aimed at reversing the “habit” of pulling.
