Trichotillomania* is a disorder characterized by an overwhelming urge to repeatedly pull out one's own hair, resulting in hair loss (alopecia). It is classified under the obsessive-compulsive and related disorders category. Trichotillomania results in highly variable patterns of hair loss. The scalp is the most common area of hair pulling, followed by the eyebrows, eyelashes, pubic and perirectal areas, axillae, limbs, torso, and face. The resulting alopecia can range from thin unnoticeable areas of hair loss to total baldness. Some people chew or swallow the hair they pull out (trichophagy), which can result in gastrointestinal problems or develop a trichobezoar (hairball in the intestines or stomach). In many cases, people with this disorder feel extreme tension when they feel an impulse, followed by relief, gratification or pleasure afterwards. The disorder may be mild and manageable, or severe and debilitating. The cause is unknown, though both environmental and genetic causes have been suspected. * Treatment may involve cognitive behavior therapy, such as habit reversal training (learning to substitute the hair-pulling behavior) and/or drug therapy, but these are not always effective.

The U.S. National Institutes of Health, through the National Library of Medicine, developed ClinicalTrials.gov to provide patients, family members, and members of the public with current information on clinical research studies. Currently, several clinical trials are identified as either completed, active, or enrolling individuals with trichotillomania. To view these trials, click here. After you click on a study, review its "eligibility" criteria to determine its appropriateness. Use the study’s contact information to learn more. Check this site often for regular updates.
You can also find relevant information about studies regarding treatment of trichotillomania through PubMed, a searchable database of biomedical journal articles. Although not all of the articles are available for free online, most articles listed in PubMed have a summary available. To obtain the full article, contact a medical/university library or your local library for interlibrary loan. You can also order articles online through the publisher’s Web site. Click here to view a PubMed search on trichotillomania. Use the "Advanced" search feature or the filters on the left side of the page to narrow your search results.
The National Library of Medicine (NLM) Web site has a page for locating libraries in your area that can provide direct access to these journals (print or online). The Web page also describes how you can get these articles through interlibrary loan and Loansome Doc (an NLM document-ordering service). You can access this page at the following link: http://nnlm.gov/members/. You can also contact the NLM toll-free at 888-346-3656 to locate libraries in your area.

Behavioral treatment seems to be the most powerful treatment for trichotillomania. Parental involvement is important and should include enough support so that affected children grow well intellectually, physically, and socially. Shaving or clipping hair close to the scalp may be helpful to stop the behavior.
Professional cognitive behavior therapy (CBT) is recommended if initial approaches are unsuccessful. CBT typically involves self monitoring (keeping records of the behavior); habit-reversal training; and stimulus control (organizing the environment). CBT is typically effective in highly motivated and compliant patients. The success of therapy may depend on firm understanding of the illness and the cooperation of the family members to help the affected individual comply with treatment. Several courses of CBT may be needed.
No medication has been approved for the treatment of trichotillomania, and medications used have not been consistently effective. Selective serotonin reuptake inhibitors have been utilized but responses to treatment have not been consistent. Fortunately, several recent studies regarding drug therapy for trichotillomania show promise. While drug therapy alone is currently generally not effective, combination therapy and other treatments may be helpful.
More detailed information about current treatment options for trichotillomania is available on Medscape Reference's Web site and can be viewed by clicking here. You may need to register on the Web site, but registration is free.
