(Trichotillomania) causes people to pull out the hair from their scalp, eyelashes, eyebrows, and other parts of the body resulting in noticeable bald patches. Approximately 5-20% of people who have hair pulling disorder also swallow the hair.
(Excoriation) causes people to repetitively touch, rub, scratch, pick at, or dig into their skin, resulting in skin discoloration, scarring, and even severe tissue damage and disfigurement.
(Onychophagia) causes people to bite their nails past the nail bed and chew on cuticles until they bleed, leading to soreness and infection.
Often referred to as "cheek chewing," chronic cheek biting can result in a myriad of complications. Redness, painful sores, and tears can occur in the mucosa, which is the inner lining of the mouth.
Frequently include cheek and lip biting, nail picking, scab eating, and other self-grooming-related behaviors.
BFRBs are among the most poorly understood, underdiagnosed, and untreated group of mental health disorders. Research suggests that causes of BFRBs include improving or correcting an imperfection in physical appearance, in addition to self-regulation of intense emotions. Several studies have shown a higher number of BFRBs in immediate family members of persons with skin picking or hair pulling than would be expected in the general population. BFRBs are not self-harm.
BFRBs are equal opportunity behaviors that affect both men and women. They are highly underreported and undiagnosed disorders, which oftentimes provides the illusion that women are more susceptible to experience hair pulling, skin picking, nail biting, cheek biting, and other associated behaviors. It is possible that men are less likely to report having a BFRB than women; therefore, present less frequently for treatment. Although research shows that more women likely suffer with hair pulling, it may be that men are just as implicated, but do not report their symptoms.
Although BFRBs can cause damage to the body, the goal is quite different than that of people who engage in self-harming behaviors. Self-harm (cutting, scratching, burning, etc.) is done with the goal of intentional harm to one’s body in an attempt to reduce the sensation of emotional pain or to manifest physical pain to drown out emotional pain. Alternately, BFRB behaviors are, for many people, self-regulating and serve some internal need. Many people who engage in BFRBs report that they are pleasurable, that they help them in some way, or that they help them to achieve some goal (symmetry or smoothness). When a person engages in their BFRB, physical damage is created as a result of their behavior but is an unintentional result of their repetitive behavior.
BFRBs are not self-harm. BFRBs are not caused by trauma.
Almost everyone with a BFRB reports pulling/picking at least some of the time when they are feeling anxious or stressed, however a host of other emotions, beliefs, sensations, and habitual triggers are also reported. The goal of therapy is to understand the internal and external triggers that lead a person to engage in their BFRB, as well as the internal and external events that reinforce them (make them more likely to happen again in the future). For some people with a BFRB, anxiety management skills are a key focus of treatment, while for others it is not a part of treatment at all. The key to good treatment is understanding what is driving the behavior for that person, and then offering interventions to address those unique drivers. Treatment for BFRBs is tailor-made to the individual and should be customized to the needs of the presenting person.
Similar to other mental health disorders, BFRBs are a combination of neurobiological, environmental, and genetic factors, not the result of “bad parenting.” In fact, most parents of children with BFRBs are quite supportive and would do just about anything to help their child with a BFRB. Conversely, there are many families fraught with trauma and abuse where BFRBs are completely absent. Unfortunately, when parents try to help and the BFRB persists, parents can become frustrated and even frightened for their child. To support parents, TLC offers ongoing health education webinars and connection to support your child in ways that feel empowering and that lead to healing.
Body-focused repetitive behaviors are complex, multidimensional problems that require a multidimensional approach. Learning to understand the function of a BFRB, emotional and physical triggers to the behavior, and having a toolbox of strategies for working through triggers and urges are crucial components of success. The articles below offer various approaches and tips to help you or your loved one on the path to recovery.
