Trichotillomania is a chronic condition where hair pulling is self-directed and irresistible for the patient.  It is often difficult to treat but with persistent attempt it can be controlled.  Predominantly psychotherapy and to some extent pharmacotherapy, can be employed to treat trichotillomania. Behavioral therapy has shown better results than pharmacotherapy in majority of studies.<ref name="van MinnenHoogduin2003">{{cite journal|last1=van Minnen|first1=Agnes|last2=Hoogduin|first2=Kees A.

Overview

Trichotillomania (TTM) is characterized by the repeated urge to pull out scalp hair, eyelashes, facial hair,pubic hair, nose hair, eyebrows or other body hair. It is a condition in which individual pulls out hair amounting to significant hair loss. It results in enormous distress and functional impairment in several areas of life. Secondary to this behavior, there is progressive deterioration of self esteem and ultimately, ends up in self-isolation. It is emotionally traumatizing as well as socially stigmatizing for the patient.

Historical Perspective

  • The term "trichotillomania" is Greek in origin. It is a compilation of three words- trich, tillo and mania.
  • "Trich" stands for hair, "tillo" means to pull and "mania" denotes an unusual fascination towards an object, place or action. The resulting word "trichotillomania" signifies the irresistible urge to pull hair. [1]
  • It was first mentioned in a published scientific report about hair pulling behavior in 1885. [2]
  • The term, however, was first used by a French dermatologist, Francois Hallopeau, in 1889.[3]
  • Originally, Francois Hallopeau had used this term for alopecia due to self-traction of hair. It has now evolved to include the syndrome of pathological hair-pulling. [4]
  • A French physician, Baudamant gave details of trichobezoar (mass of undigested hair in gastrointestinal tract) in a 16 year-old adolescent in the late 18th centuary.[5]

Classification

  • Among the classification systems, trichotillomania was first mentioned in ICD-9 in 1975 under 'the other disorders of impulse control'.
  • DSM-III-R first included trichotillomania in 1987 as an 'impulse control disorder, not classified elsewhere'. [6]
  • In 1990, trichotillomania was accepted as an independent disorder in ICD-10. It has been included under 'the habit and impulse control' category[7]
  • In DSM-IV, two minimal modifications were made regarding the details of the disorder's descriptions. Criteria B emphasized more on the stress experienced while resisting to pull the hair. The distress and impairment experienced by the individual were also brought into focus as enclosed in Criteria E. [8][9]
  • In DSM-IV-TR also trichotillomania has been described as 'an impulse control disorder, not classified else where'.[10]
  • Therefore, it would be appropriate to point here that DSM had minor changes in the description of trichotillomania till the classification change in DSM-5.
  • Earlier it was considered an impulse control disorder but DSM-5 included it under the 'Obsessive Compulsive and Related Disorders' (OCRD).
  • Unlike DSM-IV, DSM-5 Criteria does not require the loss of hair in trichotillomania to be noticable. The individuals with this condition may pull out the hair from a wider region making it difficult to distinguish.[11]
  • DSM-5 has included a criteria that makes it mandatory that the individual should have made repeated attempts to discontinue hair pulling behavior to be diagnosed as trichotillomania. This has replaced the DSM-IV criteria of preceding tension and immense gratification following hair pulling. [12] This explains the transition from impulse control disorder to OCRD of DSM-5.
  • It has further made it clear that the condition should not be secondary to medical (various dermatological conditions) or psychiatric (Body dysmorhic disorder, psychosis, Obsessive Compulsive Disorder etc) disorders.

Pathophysiology

  • Pathophysiology of trichotillomania is proposed to be related to the dysregulation of glutaminergic system.[13].
  • Similar to body dysmorphic disorder, impulse control disorder, kleptomania and tourette's syndrome, individuals with TTM have a reduced ability to transport serotonin at the presynaptic level.[14]
  • The imaging studies performed on individuals with trichotillomania have shown involvement of various brain regions.
  • In patients with trichotillomania, there are subcortical brain abnormalities noted on Magnetic Resonance Imaging (MRI Scan). The decreased putamen and amygdala volumes as well as variation in curvature of caudate and nucleus accumbens points towards their involvement in affect modulation and reward processing, which forms the basis of trichotillomania pathophysiology. [15]
  • MRI findings have also shown that in patients with trichotillomania, there is reduced volume of both right and left cerebellar cortices. It is further substantiated by the motor involvement in symptomatology of this disorder. [16]
  • An increase in right frontal cortical thickness has been observed in these individuals. However, the extent of thickness does not correspond to the severity of symptoms.[17]
  • The white matter tracts are also affected in trichotillomania. They have a role in habit formation and suppression as well as affect regulation.
  • Reduction in fractional anisotropy has been noticed in anterior cingulate, and temporal cortical region. It has not been found to relate with disease severity. [18]
  • Therefore, this disorder has complex pathophysiology which is further substantiated by the involvement of numerous brain areas as shown on neuroimaging.

Clinical Features

Differential Diagnosis

Trichotillomania should be differentiated from other medical and psychiatric conditions like-[28][29]

  • Other medical conditions-
  • Neuro-developmental disorder

Epidemiology and Demographics

Prevalence

The prevalence of trichotillomania is 1,000-2,000 per 100,000 (1%-2%) of the overall population.[28] The number of reported cases have increased over the years, likely due to a decreased perceived stigma.

Age

  • Patients of all age groups may develop trichotillomania.
  • Based on the age at onset, it is divided predominantly into three types- children of pre-school age, pre-adolescents and adolescents, and adults.[30]
  • Contrary to the popular belief, childhood-onset trichotillomania is common but differs in the neurobiology from the adult-onset type. [31]
  • From childhood to adolescence, hair pulling increases in focused manner whereas the automatic hair pulling remains the same.[32]
  • As the children grow older, reaching the adolescent group more frequent urges have been noticed and there has also been decreased ability to resist. [33]
  • It has been observed that post-pubertal onset is associated with greater severity of symptoms. [34]

Gender

  • Sixty-five percent of those affected are females.[35]
  • Most of studies support the female predominance but there are some studies showing both genders being equally affected by this condition. [36]
  • With the male and female subjects having the same severity of symptoms, the females experience more distress and functional impairment due to hair pulling. [37]
  • It has been observed that men have later age of onset of trichotillomania and were found to be significantly affected by the coexisting anxiety.[38]
  • In females who have trichotillomania, the symptoms exacerbate during menstruation. The condition may start during pregnancy or soon after birth of the child. [39]

Race

  • African American females mostly pull their hair from the scalp region like their white counterparts.[40]
  • Caucasians reported more pulling hair from eyebrows and eyelashes, more tension before hair pulling, higher interruption in their academic life and greater stress experienced on a day-to-day basis when compared to their minority counterparts.[41]
  • Before hair pulling, anxiety has been the predominant feature observed in African American adults. [42]

Risk Factors

The risk factors associated with trichotillomania are-[43]

Natural History, Complications and Prognosis

  • Individuals with trichotillomania can spend normal lives but they may have bald spots on their head, among their eyelashes, pubic hair, or eyebrows.
  • It is associated with a significant psychological effect characterized by low self-esteem, often associated with the feeling of outcast by the peers.
  • They develop the fear of interacting with others due to their appearance and dread the social rejection they might encounter.
  • These people wear hats, wigs or style their hair in an attempt to avoid attention.
  • It is a stress related condition. In low-stress environments, some individuals exhibit no symptoms whereas the 'hair pulling' resumes upon leaving this environment.[46]

Treatment

Trichotillomania is a chronic condition where hair pulling is self-directed and irresistible for the patient. It is often difficult to treat but with persistent attempts, it can be controlled. Predominantly psychotherapy and to some extent pharmacotherapy, can be employed to treat trichotillomania. Behavioral therapy has shown better results than pharmacotherapy in majority of studies.[51] [52]Contrary to this, some studies suggest the combination of two present with promising results.[53]

Psychotherapy

  • Habit Reversal Training (HRT) has been considered a productive adjunct to pharmacotherapy for managing trichotillomania.[54]
  • HRT focuses on increasing awareness of the patients about the behavior that is desired to be controlled. The emphasis is on gaining information about the pattern of the behavior and finding out a way to control it ahead of time. They are also trained to decrease the tension before the hair pulling.
  • Some studies have considered HRT superior to pharmacotherapy in controlling trichotillomania.[55]
  • Other therapy options like Cognitive Behavioral Therapy (CBT) have also been tried but after successful treatment, it has been observed that there are higher chances of relapse with CBT. [56]
  • Group supportive therapy has also been associated with minimal improvement in the condition. Infact, behavior therapy when employed in groups also revealed lesser favorable outcomes than individual therapy. [57]
