Body-focused repetitive behaviours (BFRBs) are a group of patterns in which people repeatedly pick at, pull out, bite, or rub parts of their bodies, causing physical harm. Common examples include trichotillomania (hair pulling), dermatillomania or excoriation disorder (skin picking), and severe nail biting (onychophagia). Other related behaviours can include cheek or lip chewing and persistent touching or rubbing of skin or hair.
Despite how common they are, BFRBs are often misunderstood. Many who live with these behaviours are told they are simply bad habits or that they should be able to stop by trying harder. This minimizes the real emotional and neurological factors involved and can increase feelings of shame or isolation, making it harder for people to get help.
The Canadian context and who is affected
BFRBs can affect people of any age, gender, or background. Research from international sources suggests that nail biting can be common in childhood and adolescence, with some estimates indicating it affects a substantial portion of youth. Trichotillomania is estimated to affect around 1–2% of people, and skin picking may affect several percent of the population at some point. These figures likely undercount the true number of people in Canada who experience these conditions because many do not seek care or do not identify their behaviour as a mental-health issue.
Families often struggle to understand why a loved one continues a behaviour that causes harm. Cultural attitudes toward mental health can also shape how people respond, whether that makes it easier to seek help or creates additional barriers.
What causes BFRBs?
BFRBs usually arise from a mix of biological, psychological, and environmental contributors:
- Genetic and neurobiological factors: Family patterns and twin studies point to a heritable component. Brain differences related to habit formation, impulse control, and sensory processing have been observed in people with BFRBs.
- Emotional triggers: Stress, anxiety, boredom, and difficulty regulating emotion commonly precede episodes. The behaviour can act as a short-term relief strategy.
- Sensory preferences: Many people are driven by sensations or perceived imperfections, texture, visual irregularities, or the feeling of a stray hair, that make a particular site a target.
Common types of BFRBs and their impacts
Trichotillomania (hair pulling)
People with trichotillomania pull hair from the scalp, eyebrows, eyelashes, or other body parts. Results range from mild thinning to noticeable bald patches. Aside from the physical effects, many invest significant time and money into hiding hair loss and may avoid activities where hair loss would be obvious.
Dermatillomania / excoriation (skin picking)
Skin picking targets perceived irregularities and can involve nails, fingers, face, arms, or legs. Consequences include scarring, infection, and extended healing. Visible marks often lead to embarrassment and social withdrawal.
Onychophagia (nail biting) and related behaviours
While many people bite their nails occasionally, chronic or severe nail biting can cause bleeding, infection, and long-term damage. Other body-focused actions, lip or cheek chewing, rubbing, or repetitive touching, can produce similar physical and psychological harm.
Navigating Canada’s health-care system
Primary care providers are usually the first contact for Canadians concerned about BFRBs. However, family doctors may have limited specialized training in these disorders and can sometimes underestimate their severity. If your doctor is unfamiliar with BFRBs, ask about referrals to mental-health specialists or clinics with expertise in obsessive and related behaviours.
Access to specialists varies across provinces and between urban and rural areas. Publicly funded mental-health services may have wait times, while private therapists can be accessed faster but often require out-of-pocket payment or coverage through employee benefits. Coverage limits differ by plan and province, so check your benefits for details on registered counsellors, psychologists, or psychiatrists.
Evidence-based treatments
Cognitive behavioural therapies are the most researched and commonly recommended treatments for BFRBs. Effective approaches typically combine several elements:
- Awareness training, learning to recognise urges, triggers, and the chain of events that lead to the behaviour.
- Stimulus control, changing the environment to reduce opportunities to engage in the behaviour (for example, removing tools used in picking or wearing gloves at risky times).
- Competing response training, practising alternative actions that are incompatible with the behaviour, like gently clenching fists or holding an object when an urge strikes.
Other psychotherapy approaches that may help include Acceptance and Commitment Therapy (ACT) and Dialectical Behaviour Therapy (DBT) skills for emotion regulation and distress tolerance. Some people benefit from medication when there are co-occurring conditions such as depression or anxiety; selective serotonin reuptake inhibitors (SSRIs) and supplements like N‑acetylcysteine have shown potential in studies, but psychological treatments generally have the strongest support.
Practical daily-management strategies
Small, consistent changes can reduce frequency and severity of episodes. Consider these steps:
- Keep a behaviour log noting time, place, mood, and what preceded the urge to find patterns.
- Modify your environment, cover mirrors, remove picking tools, or keep nails trimmed to reduce temptation.
- Carry or place alternative items within reach: fidget toys, stress balls, or sensory objects that satisfy similar needs.
- Practice mindfulness and relaxation routines (deep breathing, progressive muscle relaxation, short meditations) to increase awareness of urges before they occur.
- Create gentle accountability with trusted friends or family who agree to offer nonjudgmental reminders or distractions.
The role of family and social support
Supportive relationships make a big difference. Family members should avoid shaming or pressuring someone to stop by willpower alone. Helpful responses include learning about BFRBs, offering calm reminders or alternative activities during high-risk periods, and assisting with environmental changes.
Peer support, online communities or local groups, can reduce isolation and provide practical tips from people with lived experience. When family dynamics are strained, family therapy can help improve communication and reduce unintentional reinforcement of the behaviour.
BFRBs across the lifespan
Childhood-onset BFRBs benefit from early, developmentally appropriate interventions: parent coaching, play-based strategies, and school collaboration. Teachers and school staff can help by providing discreet supports such as fidget tools or scheduled breaks.
Adolescents may experience worsening symptoms due to hormones, social stress, and academic pressure; engaging teens in treatment requires balancing support with respect for their autonomy. Adults may have longstanding patterns that need more intensive work but often also have greater motivation and insight to engage in therapy.
Pregnancy and postpartum periods can alter symptom patterns. Treatment decisions during these times should carefully weigh benefits and risks, especially regarding medication.
Recovery and relapse prevention
Recovery is rarely a straight line. For some people, full cessation is possible; for others, the goal may be reduced frequency, less physical harm, and improved quality of life. Relapse prevention focuses on spotting early warning signs, adjusting strategies when life stressors arise, and maintaining routines that support mental health, good sleep, exercise, social connections, and stress management.
Frequently asked questions
Are BFRBs serious?
Yes. BFRBs are recognised in diagnostic manuals and can lead to physical injury, emotional distress, and impaired daily functioning. They are not simple bad habits.
Can they be fully cured?
Outcomes vary. Many people make meaningful improvements with therapy and self-management. Some stop entirely; others learn to reduce impact and regain control over their lives.
Will Canada’s public health system cover treatment?
Coverage differs by province and service type. Medical treatment for complications (e.g., infections) is covered, but access to specialized psychological care may require private payment or insurance. Speak with your primary-care provider about referral options and community resources.
Should I tell my doctor?
Yes. Discussing BFRBs with a health professional helps address physical risks and opens the door to appropriate mental-health referrals.
Where to go for help
Start with your family doctor or a mental-health professional who has experience with compulsive and body-focused behaviours. If local resources are limited, ask about teletherapy options or provincial mental-health services. Peer support groups and reputable online resources can offer interim support while you arrange professional care.
