Understanding Compulsive Self-Mutilation

Skin picking, nail-biting, hair-pulling—it’s not uncommon to occasionally fuss with your hair or pick at an annoying scab. For some people, however, that fussing turns into a compulsive behavior that is both destructive and embarrassing. From constantly biting one’s nails to cutting one’s skin when strong emotions hit, these repetitive behaviors often have a serious physical and emotional impact. Understanding compulsive self-mutilation and the possible causes behind it can help you address your own behaviors, as well as support someone you know who may be struggling.

Types of Self-Mutilation


Although alarming to others, individuals who engage in this type of compulsive self-mutilation don’t do it with the intent to kill themselves. Rather, they almost always use it as a way to cope with intense negative feelings. The impulsive act of cutting gives the person a sense of control over his or her emotional pain. For many who engage in this type of behavior, self-harm actually releases endorphins that provide a sense of pleasure.

The arms and wrists are the most commonly cut areas. Sadly, cutting often leaves permanent, unsightly scars. Cutting occurs most frequently in adolescents, but for some individuals—particularly many diagnosed with borderline personality disorder—it can continue into adulthood.

Hair Pulling

Also known as trichotillomania, individuals with this impulse-control disorder have the uncontrollable urge to pull out hair from their head, eyebrows, eyelashes, or arms. Feelings of anxiety often trigger the urge. The hair-pulling behavior relieves the tensions and provides a feeling of satisfaction—at least temporarily. It’s common for those with trichotillomania to also compulsively twirl their hair, inspect their hair’s roots, and chew on their hair. Unfortunately, the behavior often results in visible patches and bald spots.

Nail Biting (Onychophagia)

This is a common habit affecting many young children. Most people, however, stop biting their nails on their own by around the age 30. Chronic and serious nail-biting can lead to scarring and infections. It can also create feelings of shame. For example, a nail-biter might become too embarrassed to shake hands. If their condition is severe, they may wear gloves to hide the self-inflicted damage.

Skin Picking (Dermatillomania)

This condition is marked by repetitive skin picking that results in tissue damage. Picking can occur on any part of the body, but common target areas include:

  • The face
  • Arms
  • Lips
  • Gums
  • Scalp
  • Chest
  • Fingers

Many individuals with dermatillomania pick with their fingers; however, some use tools like fingernail clippers or tweezers. Skin picking can cause infections, interferes with the healing of wounds, and often leave visible scars.

The Effects of Compulsive Self-Mutilation

All of these compulsive behaviors can have a significant negative impact on a person’s emotional and physical well-being. Emotionally, self-mutilation produces feelings of shame and low self-esteem. A person may also feel guilty for compulsively engaging in behavior they understand is not normal. The injuries take a physical toll as well in the form of lesions, ulceration, infections, and scarring. Cutting, in particular, carries the risk of life-threatening complications if a major blood vessel is cut.

Causes of Compulsive Self-Mutilation

Researchers have yet to identify one clear source for self-mutilation behaviors. Some studies suggest that skin picking is related to substance use disorders; the person engages in it despite knowing its potential harm and often reports pleasure during the activity. Others research suggests these conditions have more in common with obsessive-compulsive disorder (OCD), falling within the obsessive-compulsive spectrum.

Self-Mutilation and Other Disorders

People who self-mutilate often have other psychiatric disorders as well, including:

  • Substance use disorders
  • Major depressive disorder
  • Anxiety disorders

Researchers estimate that between 6% and 19% of people who compulsively pick skin also meet the criteria for OCD. Cutting behavior has been linked to several mental health conditions, including schizophrenia and borderline personality disorder. Borderline personality disorder is marked by unstable moods, feelings of emptiness, and a disturbed sense of self. This kind of self-harm is often used as a way to cope with the pain caused by serious trauma, such as physical or sexual abuse. This is why compulsive cutting is sometimes found in those with post-traumatic stress disorder (PTSD).

Treating Compulsive Self-Mutilation

One of the most effective types of treatment for compulsive self-mutilation disorders is cognitive-behavioral therapy (CBT). The goal of CBT is to help the individual identify unhealthy and irrational thought patterns and re-wire their thinking. By doing so, they can learn to replace the self-harm behavior with healthy ways to cope with anxiety, emotional pain, and other triggers. Researchers have found that CBT is far more effective than a medication-only approach.

Since people who struggle with compulsive self-mutilation often suffer from other psychiatric disorders, such as PTSD or major depression, a successful treatment plan will also integrate therapies to address those conditions as well. One of the challenges with compulsive self-mutilation is that the damage may also generate physical injury that requires medical treatment. Cutting, hair pulling, and skin picking can lead to infection and scarring that requires treatment by a dermatologist or other type of physician.

Self-help strategies are essential tools for managing and eliminating self-mutilating behaviors. These include:

  • Managing stress. Making time for a relaxing hobby or volunteer work will also provide the physical and emotional relief needed to resist cutting, skin picking, and other behaviors.
  • Expressing emotions. Convey your emotions through activities like writing, singing, painting, or dancing. Talking with friends or a support group will also give you an outlet for negative feelings.
  • Keeping hands busy. A fidget toy can be any object you can fiddle around with, like a small squeeze ball or stress ball. Small craft projects, like knitting or crocheting, can also keep your hands busy during long periods of inactivity, such as watching television or riding in the car.
