Body-focused repetitive behaviors may include any repetitive self-grooming behavior that involves biting, pulling, picking, or scraping one’s own hair, skin, or nails that results in damage to the body. While most people engage in one or some of these behaviors to a certain degree, an individual may want to seek help and support if the behavior begins to limit their life in some way, feels out of control, causes physical damage, or is causing social impact. These repetitive behaviors are not uncommon, yet there is very little empirical data in the scientific literature.

Other Body-Focused Repetitive Behaviors

Body-focused repetitive behaviors include any repetitive self-grooming behavior that involves biting, pulling, picking, or scraping one’s own hair, skin, or nails that results in damage to the body.

Some of the BFRBs listed below are not specifically indexed in the Diagnostic and Statistical Manual of Mental Disorders – Fifth Edition (DSM-5).  They are classified as “other specified obsessive-compulsive and related disorders", with specification of “body-focused repetitive behaviors.”

Other BFRBs Include

Hair Cutting (Trichotemnomania)

Is characterized by the compulsive cutting of one's own hair to achieve some visual goal like evenness or visual improvement.

Hair Eating (Trichophagia)

Occurs in approximately 15% of patients with hair pulling disorder or trichotillomania. Eating hair may cause serious medical complications in the form of trichobezoars – hairballs that may form in the stomach or bowel. Bezoars can be life-threatening. If you or your child experiences the following symptoms, it is recommended you seek advice from a medical doctor: feeling sick, vomiting, stomach pain, foul breath, or other symptoms of gastrointestinal problems.

Lip Biting (Lip Bite Keratosis)
Involves the repetitive biting of the skin of one’s own lips.

Nail Picking (Onychotillomania)

Involves the destruction of the fingernails or toenails by means of chronic picking of the nails. 

Skin Biting (Dermatophagia)

Often occurs among patients with onychophagia. Skin biting behaviors include biting the cuticles or fingers, and digesting scabs or skin (usually as a result of skin picking disorder). Oftentimes, lip, cheek, and tongue biting are also considered dermatophagia.

Tongue Chewing

Chronic chewing on the tongue, most frequently the sides of the tongue, to the point of damage is a common oral problem and is considered to be a body-focused repetitive behavior (BFRB).

Impacts and Effects

The impact of BFRBs on one's life may be significant. Individuals may experience shame and embarrassment, and as a result, may avoid certain social situations or activities (e.g., pools, gyms, beaches), and medical care. These behaviors can lead to painful isolation and result in a great deal of emotional distress, placing them at risk for a co-occurring psychiatric disorder, such as a mood or anxiety disorder. The most successful management strategies make use of a variety of therapeutic techniques that address actionable emotional and behavioral components. While learning how to manage the behavior, it is important to remember that emotional discomfort that influences the behavior is subjective rather than objective. This realization empowers you to choose how you experience these emotions and enables you to alter your behavior.

Individuals who experience BFRBs often go to great lengths to cover, hide, or camouflage damage to the scalp, skin, nails, and may have difficulty with time management due to the significant time involved in engaging in the behavior as well as efforts to conceal it.

Medical complications as a result of BFRBs are not uncommon and may include physical effects such as pruritus, tissue damage, infection, and repetitive motion injuries to the muscles or joints. Other medical complications can include scabbing, open wounds, discoloration, scarring, or disfigurement, damage to the cuticles and nails, bacterial and viral infection, cellulitis, abscess, injury to the soft tissue lining the mouth, dental problems, temporomandibular dysfunction, and osteomyelitis.

BFRBs can lead to strained relationships with family members and friends. Family members may need professional help to cope with their loved one's behaviors.


Research into treatments for BFRBs, particularly hair pulling and skin picking, has grown steadily over the past decade. Although no one treatment has been found to be effective for everyone, a number of evidence-based treatment options have shown promise for many people.
