Trichotillomania (trik-o-til-o-MAY-nee-uh), also called hair-pulling disorder, is a mental health condition. It involves frequent, repeated and irresistible urges to pull out hair from your scalp, eyebrows or other areas of your body. You may try to resist the urges, but you can't stop. Trichotillomania is part of a group of conditions known as body-focused repetitive behaviors.

Pulling out hair from the scalp often leaves patchy bald spots. This can cause a lot of distress and can affect your work, school and social life. You may go to great lengths to hide the hair loss.

For some people, trichotillomania may be mild and can be managed. For others, the automatic or deliberate urge to pull out hair is too much to handle emotionally. Some treatment options may help reduce hair pulling or stop it entirely.


Symptoms of trichotillomania often include:

  • Repeatedly pulling out your hair, whether it's automatic or on purpose, usually from your scalp, eyebrows or eyelashes, but sometimes from other body areas. The sites may vary over time.
  • An increasing sense of tension before pulling out your hair, or when you try to resist pulling.
  • A sense of pleasure or relief after the hair is pulled out.
  • Hair loss that's easy to see, such as shortened hair or thinned or bald areas on the scalp or other areas of your body. This may include thin or missing eyelashes or eyebrows.
  • Pulling out specific types of hair, taking the same steps in the same way each time hair is pulled out or pulling out hair in certain patterns.
  • Biting, chewing or eating pulled-out hair.
  • Playing with pulled-out hair or rubbing it across your lips or face.
  • Repeatedly trying to stop pulling out your hair or trying to do it less often without success.
  • Experiencing a great deal of distress or problems at work, school or in social situations related to pulling out your hair.

Often trichotillomania also includes picking your skin, biting your nails or chewing your lips. Sometimes pulling out hairs from pets or dolls or from materials, such as clothes or blankets, may be a sign. Pulling out hair is usually done in private. An episode can last from a few seconds to hours. You may try to hide your condition from others.

With trichotillomania, pulling out hair can be:

  • Automatic. You may pull out your hair without even realizing that you're doing it. This might happen, for example, when you're bored, reading or watching TV.
  • Focused. You may pull out your hair on purpose to relieve tension or distress. You may develop specific rituals for pulling out hair, such as finding just the right hair. You may play with, bite or eat pulled-out hairs.

You may do both automatic and focused hair pulling, depending on the situation and your mood. Certain positions or activities may trigger pulling out hair, such as resting your head on your hand or brushing your hair.

Trichotillomania can be related to emotions, including:

  • Negative feelings. Pulling out hair may be a way of dealing with negative or uncomfortable feelings, such as stress, anxiety, tension, boredom, loneliness, extreme tiredness or frustration.
  • Positive feelings. You may find that pulling out hair feels satisfying and provides some relief. As a result, you may continue to pull out your hair to keep these positive feelings.

Trichotillomania is a long-term disorder. If not treated, symptoms may come and go for weeks, months or years at a time. Also, symptoms can vary in severity over time. For example, hormone changes during the menstrual period can worsen symptoms in some females. Rarely, pulling out hair ends within a few years of starting.

When to see a doctor

If you can't stop pulling out your hair or you feel embarrassed or ashamed by your appearance as a result, talk to your health care provider. Trichotillomania is not just a bad habit, it's a mental health condition. It's not likely to get better without treatment.


The cause of trichotillomania is not clear. But like many complex disorders, trichotillomania likely results from a combination of genetic and learned factors.

Risk factors

These factors tend to increase the risk of trichotillomania:

  • Family history. Genetics may play a role in the development of trichotillomania. You may be more likely to have the condition if you have a close relative with trichotillomania.
  • Health conditions. Some people may have hair or skin conditions that feel uncomfortable. This may focus their attention toward pulling hair or picking at their scalp.
  • Age. Trichotillomania usually develops just before or during the early teens — most often between the ages of 10 and 13 years. It's often a lifelong problem. Babies may pull out their hair, but this is usually mild and goes away on its own without treatment.
  • Other mental health conditions. Other conditions, such as depression, anxiety or obsessive-compulsive disorder (OCD) may occur along with trichotillomania.
  • Stress. Severely stressful situations or events may trigger trichotillomania in some people.
  • Environment. Boredom, isolation and privacy often increase the likelihood of hair pulling.

Although far more women than men are treated for trichotillomania, this may be because women are more likely to seek medical advice. In early childhood, trichotillomania occurs just as often in boys and girls.


Although it may not seem serious, trichotillomania can have harmful effects on your life. Complications may include:

  • Emotional distress. You may feel frustrated, ashamed and embarrassed because of your condition and hair loss. You may feel that you don't have control over pulling out your hair. You may experience low self-esteem, depression, anxiety, and problems with alcohol or drugs.
  • Problems in your social life and with work. Hair loss may lead you to avoid social activities and school and job opportunities. You may wear wigs, style your hair to disguise bald patches or wear false eyelashes. You may avoid intimacy to hide your condition.
  • Skin and hair damage. Constantly pulling out hair can cause scarring, infections and other damage to the skin on your scalp or the area where hair is pulled out. This can permanently affect hair growth.
  • Hairballs. Eating your hair may lead to a large, matted hairball that stays in your digestive tract. Over a period of years, the hairball can cause weight loss, vomiting, an intestinal block and even death.
