Trichotillomania is an impulse control disorder marked by the urge to pull out scalp hair, eyelashes, eyebrows and other body hair.
The symptoms are generally reported by friends or family members of the person directly plucking of one’s hair, resulting in significant hair loss. Patients usually pluck one hair at a time and the urge is continuous lasting for hours together.
There are phases of remission in between two episodes. This phase of remission can continue for many days or months or even few years. Patients seek solitude while doing this activity. They are affected psychologically and suffer from fear of appearing socially  . They manipulate their appearance in order to look appealing. This is done by wearing hair extensions or hats, scarves etc.
Hair pulling is highly prevalent in association with stress and anxiety. The individual feels mentally relieved and his anxiety reduces by pulling his hair. Some people also ingest the plucked hair. This leads to formation of trichobezoar, a hair ball formation in the gut. An extreme form of trichobezoar leads to the hair ball tail extending to the intestine . This condition is called Rapunzel disease. This condition is fatal if not diagnosed. Other factors such as a sedentary lifestyle, lying in bed, idealism can contribute to such activity. Children are especially prone to develop this habit.
Microscopic examination of the collected plucked hair helps in the diagnosis of this condition. The pattern of hair suggests the anagen or telogen count. Anagen hair are typical of trichotillomania. Multiple longitudinal and transverse sections are obtained  . The hair showing an exclamation mark are typical of alopecia areata. Biopsy from the scalp is the most reliable in achieving the diagnosis.
Before initiating any treatment, evaluation of the case is necessary. First determine whether the symptoms represent more of a habit than a real disorder. Secondly, one must evaluate whether the patient requires further investigations such as MRI or a CT scan to rule out further pathology such as trichobezoars syndrome. Thirdly, its necessary to evaluate the level to which the patient is affected psychologically  . This is achieved with the help of a psychiatrist or a clinical psychologist.
The treatment is mainly with behavioral correction. This includes ways to reduce and deal with stress. Observing and evaluating one’s own behavior before and after the episodes. Training the patient by teaching them forms of alternative behavior during the time he feels the urge to start pulling hair. This alternative activity should be socially sound. They are encouraged to practice it regularly and frequently. Certain relaxation techniques are advised to help in relaxing the mind.
In general, for reversing this habit, the role of parents is very important. Initial aid needs parent’s attention and care . They should support them socially and personally and communicate with them frequently.
Medications include antidepressants to reduce mental disturbance. These are mainly tricyclic antidepressants that act to interfere with the serotonin uptake by the neurons. Fluoxetine and sertraline are commonly used and they are found to be safe for children aged 8 to 17 years  .
Younger children show excellent prognosis as in them this disorder is more like a habit. As age increases the prognosis is usually fair. In older age group, the prognosis deteriorates and cure is rare. This illness causes more morbidity than mortality.
There is social and occupational distress especially in the adult age group. The illness usually lasts from weeks to many years; hence, a planned treatment under an excellent psychiatrist is very important. Eating of the pulled out hair leads to conditions such as anemia, gastric complaints, intestinal obstruction and also icterus  . It must be immediately attended to.
Theories suggest that an individual releases his or her stress and anxiety by pulling his hair. It like a coping mechanism for stress and is often to be present together with thumbsucking in younger patients . It is related to compulsive disorders as changes are observed in certain neurotransmitters like serotonin, leading to obsessive compulsive disorder .
This is an inherited disorder and often runs in families. There are changes in a particular gene leading to trichotillomania. In some individuals, this disorder helps in easing out one’s emotional distress; hence, in a way they harm themselves to seek relief from anxiety and mental stress. Certain degenerative neurological disorders such as Parkinson’s and dementia are also associated with trichotillomania.
Many individuals deny of suffering from this disorder. In the US, about 8 million people are estimated to be suffering from this illness. Trichotillomania is prevalent in all age groups, most commonly between 12-13 years. Females are more common and female to male ratio is 3 by 1  .
Hair pulling areas differ with age. Those who are young are found to pull more of eyelashes and eyebrows and those with a significantly older age pull more of pubic hair .
As trichotillomania is a psychiatric disorder, its neurobiological studies are inadequately conclusive. Certain studies reveal that changes in the basal ganglia lead to this habit forming disorder. After studying the MRI scans of about 18 patients of trichotillomania and other 18 normal healthy subjects, it was concluded that decrease in the cerebellar volume and increase in the amount of the gray matter were important findings noted with individuals suffering from trichotillomania. 
Many individuals do not accept or want to be aware of the problem of hair plucking they suffer from until it’s too late. Hence, in order to stop its further progress firstly the person should be committed; he should accept his illness and increase his willingness to overcome the disorder. This can be achieved by noticing triggers, urges, feelings when he gets the desire.
The next step is to use obstacles such as wearing gloves, or clipping the hair together, shaving that part of hair to a very short size or even putting straps on fingers. This interrupts the activity and helps the person to become conscious before he attempts such an unwanted activity . This repulsion of desire could lasts for few minutes or hours.
Aim should be made to increase the amount of plucking-free time. Patients should be encouraged and rewarded for every effort put by them in this process. Their emotions anxiety should be inquired and an appropriate counseling treatment should be initiated.
Most often, the person pulls scalp hair, but it can be from any other body part also such as eyebrows, eyelashes, beard or pubic area. This can result in baldness of that area. It has been categorized as a mental and behavioral abnormality. Any dermatologic link does not exist .
