Researchers estimate that 1-2% of the U.S. population has trichotillomania - a compulsion to repetitively pull or pluck one’s hair, resulting in noticeable hair loss. Many people with trichotillomania feel ashamed and embarrassed by their hair pulling, attempt to hide it from friends, co-workers and family members, and do not seek help. Many who consult their personal physician or a dermatologist because of hair loss never reveal the true cause and doctors often fail to consider this diagnosis.
Although trichotillomania can begin in very young children or middle-aged adults, the most common age of onset is during early adolescence. Women seem to be affected more than men with some estimates suggesting a ratio of 3 women to every man.
On the other hand, in contrast to OCD, people with trichotillomania tend not to have obsessive thoughts, do not engage in rituals other than hair pulling, and have a different pattern of abnormal brain metabolism. Also, trichotillomania patients are more likely to be women while OCD has a more even gender distribution. Consequently, the relationship of trichotillomania to OCD is not fully understood; currently they are thought to be related but distinct disorders.
Most people with the condition experience anxiety; embarrassment, and diminished self-confidence and self-esteem. Attempts to keep the condition a secret can lead to avoidance of everyday activities such as visits to the hairdresser, sports, exercise, dancing, public showers, swimming, and being in brightly lit rooms. Some avoid treatment for medical or dental problems because of concern that their hair pulling will be discovered. Many go to great lengths to conceal their hair pulling and try to camouflage hair loss with different hair styles, make-up, clothing, or wigs or other hair pieces.
Hair pulling very rarely causes irreversible baldness. However, when the behavior stops, hair occasionally grows back gray or white and it may be finer, coarser, or curlier. These changes may normalize over time. While hair pulling is going on, scalp inflammation, irritation, itchiness, and tenderness are common. The trauma of hair pulling also increases the risk for scalp infection. Sometimes repetitive hair pulling can cause problems such as carpal tunnel syndrome, tendonitis, and neck/back strain. Perhaps the most common serious medical complication of trichotillomania is avoiding medical care for other illnesses because of the shame associated with hair pulling and the fear of its discovery.
Some researchers have found that nearly 20% of hair pullers eat their hair or chew off and swallow the root ends. Called trichophagy, it can lead to hair being lodged between the teeth and more seriously to large accumulations of retained hairs in the stomach and digestive tract called trichobezoars (hairballs).
Symptoms of trichobezoars include abdominal pain, nausea, vomiting, and sometimes blood and/or visible hairs in the stool. Trichobezoars can also cause foul breath, poor appetite, constipation, diarrhea, excessive gas, bowel obstruction, and even bowel perforation. Liver and pancreas functions can be adversely altered. Sometimes a physician can feel a trichobezoar by gently pushing in the mid or left upper area of a patient's abdomen. Trichobezoars can be diagnosed by using special upper gastrointestinal x-rays, looking into the stomach with an endoscope, or using ultrasound. Surgical removal is the most common treatment.
Some researchers have described early onset (childhood) and later onset (adolescence) types of trichotillomania. There is no clear evidence that children with this form of the disorder are at increased risk for developing future psychiatric problems. However, children who are four, five or six and are still pulling their hair may begin to overlap with the later onset type trichotillomania which has a less favorable prognosis.

Anxiety: Apprehension of danger, or dread, accompanied by nervous restlessness, tension, increased heart rate, and shortness of breath unrelated to a clearly identifiable stimulus.
Calcium: The body's most abundant mineral. Its primary function is to help build and maintain bones and teeth. Calcium is also important to heart health, nerves, muscles and skin. Calcium helps control blood acid-alkaline balance, plays a role in cell division, muscle growth and iron utilization, activates certain enzymes, and helps transport nutrients through cell membranes. Calcium also forms a cellular cement called ground substance that helps hold cells and tissues together.
Carpal Tunnel Syndrome: A common, painful defect of the wrist and hand. It is caused by pressure on the middle nerve in the carpal tunnel. The syndrome is seen more often in women, especially in pregnant and in menopausal women. Symptoms may result from a blow, swelling, a tumor, rheumatoid arthritis, or a small carpal tunnel that squeezes the nerve. Pain may be infrequent or constant and is often most intense at night.
Choline: A lipotropic substance sometimes included in the vitamin B complex as essential for the metabolism of fats in the body. Precursor to acetylcholine, a major neurotransmitter in the brain. Choline prevents the deposition of fats in the liver and facilitates the movement of fats into the cells. Deficiency leads to cirrhosis of the liver.
Constipation: Difficult, incomplete, or infrequent evacuation of dry, hardened feces from the bowels.
Copper: An essential mineral that is a component of several important enzymes in the body and is essential to good health. Copper is found in all body tissues. Copper deficiency leads to a variety of abnormalities, including anemia, skeletal defects, degeneration of the nervous system, reproductive failure, pronounced cardiovascular lesions, elevated blood cholesterol, impaired immunity and defects in the pigmentation and structure of hair. Copper is involved in iron incorporation into hemoglobin. It is also involved with vitamin C in the formation of collagen and the proper functioning in central nervous system. More than a dozen enzymes have been found to contain copper. The best studied are superoxide dismutase (SOD), cytochrome C oxidase, catalase, dopamine hydroxylase, uricase, tryptophan dioxygenase, lecithinase and other monoamine and diamine oxidases.
Diarrhea: Excessive discharge of contents of bowel.
Endoscope: Instrument for examining the interior of a hollow organ.
Folic Acid: A B-complex vitamin that functions along with vitamin B-12 and vitamin C in the utilization of proteins. It has an essential role in the formation of heme (the iron containing protein in hemoglobin necessary for the formation of red blood cells) and DNA. Folic acid is essential during pregnancy to prevent neural tubular defects in the developing fetus.
Gastrointestinal: Pertaining to the stomach, small and large intestines, colon, rectum, liver, pancreas, and gallbladder.
Inositol: Usually considered part of the vitamin B complex. It is thought that along with choline, inositol is necessary for the formation of lecithin within the body. Involved in calcium mobilization.
Magnesium: An essential mineral. The chief function of magnesium is to activate certain enzymes, especially those related to carbohydrate metabolism. Another role is to maintain the electrical potential across nerve and muscle membranes. It is essential for proper heartbeat and nerve transmission. Magnesium controls many cellular functions. It is involved in protein formation, DNA production and function and in the storage and release of energy in ATP. Magnesium is closely related to calcium and phosphorus in body function. The average adult body contains approximately one ounce of magnesium. It is the fifth mineral in abundance within the body--behind calcium, phosphorus, potassium and sodium. Although about 70 percent of the body's magnesium is contained in the teeth and bones, its most important functions are carried out by the remainder which is present in the cells of the soft tissues and in the fluid surrounding those cells.
Metabolism: The chemical processes of living cells in which energy is produced in order to replace and repair tissues and maintain a healthy body. Responsible for the production of energy, biosynthesis of important substances, and degradation of various compounds.
Nausea: Symptoms resulting from an inclination to vomit.
Neurotransmitters: Chemicals in the brain that aid in the transmission of nerve impulses. Various Neurotransmitters are responsible for different functions including controlling mood and muscle movement and inhibiting or causing the sensation of pain.
Obsessive-Compulsive: People with Obsessive-Compulsive Disorder (OCD) have obsessions and/or compulsions. Obsessions refer to recurrent and persistent thoughts, impulses, or images that are intrusive and cause severe anxiety or distress. Compulsions refer to repetitive behaviors and rituals (such as hand washing, hoarding, ordering, checking) or mental acts (like counting, repeating words silently, avoiding). These obsessions and compulsions significantly interfere with normal routine, functioning, social activities and relationships.
pH: A measure of an environment's acidity or alkalinity. The more acidic the solution, the lower the pH. For example, a pH of 1 is very acidic; a pH of 7 is neutral; a pH of 14 is very alkaline.
Serotonin: A phenolic amine neurotransmitter (C10H12N2O) that is a powerful vasoconstrictor and is found especially in the brain, blood serum and gastric membranes of mammals. Considered essential for relaxation, sleep, and concentration.
Stomach: A hollow, muscular, J-shaped pouch located in the upper part of the abdomen to the left of the midline. The upper end (fundus) is large and dome-shaped; the area just below the fundus is called the body of the stomach. The fundus and the body are often referred to as the cardiac portion of the stomach. The lower (pyloric) portion curves downward and to the right and includes the antrum and the pylorus. The function of the stomach is to begin digestion by physically breaking down food received from the esophagus. The tissues of the stomach wall are composed of three types of muscle fibers: circular, longitudinal and oblique. These fibers create structural elasticity and contractibility, both of which are needed for digestion. The stomach mucosa contains cells which secrete hydrochloric acid and this in turn activates the other gastric enzymes pepsin and rennin. To protect itself from being destroyed by its own enzymes, the stomach’s mucous lining must constantly regenerate itself.
Vitamin A: A fat-soluble vitamin essential to one's health. Plays an important part in the growth and repair of body tissue, protects epithelial tissue, helps maintain the skin and is necessary for night vision. It is also necessary for normal growth and formation of bones and teeth. For Vitamin A only, 1mg translates to 833 IU.
Vitamin B6: Influences many body functions including regulating blood glucose levels, manufacturing hemoglobin and aiding the utilization of protein, carbohydrates and fats. It also aids in the function of the nervous system.
Yeast: A single-cell organism that may cause infection in the mouth, vagina, gastrointestinal tract, and any or all bodily parts. Common yeast infections include candidiasis and thrush.
Zinc: An essential trace mineral. The functions of zinc are enzymatic. There are over 70 metalloenzymes known to require zinc for their functions. The main biochemicals in which zinc has been found to be necessary include: enzymes and enzymatic function, protein synthesis and carbohydrate metabolism. Zinc is a constituent of insulin and male reproductive fluid. Zinc is necessary for the proper metabolism of alcohol, to get rid of the lactic acid that builds up in working muscles and to transfer it to the lungs. Zinc is involved in the health of the immune system, assists vitamin A utilization and is involved in the formation of bone and teeth.
