Dermatology - Trichotillomania 
Patients with trichotillomania may deny pulling or plucking their own hair. Trichotillomania is a compulsive desire or habit to pluck hair that may be related to a specific event or persistent stress.
Hair loss can occur on the scalp or in any area that has hair, such as the beard. There is a convergence of small patches of baldness, normal scalp area, and extremely short sparse hairs. Hair loss is typically more noticeable on the dominant hand's side and can coexist with neurotic episodes brought on by forceful tweezer plucking. There are anagen hairs or bluntly broken hairs under the microscope.Clinical diagnosis is determined only after all other potential causes of hair loss have been ruled out.
Careful differential diagnosis is the first step in managing obsessive-compulsive disorder, depression, or other underlying psychiatric issues. This is followed by psychiatric diagnosis and treatment.
