Trichotillomania (TTM), also known as hair‐pulling disorder, is characterised by an uncontrollable and persistent compulsion to pull out one’s own hair, which results in noticeable hair loss. TTM, which belongs to a group of body-focused repetitive behaviour disorders (BFRBDs), considerably affects the quality of life by producing a sense of own unattractiveness, low self-esteem, dissatisfaction with the appearance of one’s own body, and the associated feelings of shame and embarrassment. As a result, the disorder leads to significant distress and impairs the patient’s functioning in both their social and working life. TTM often coexists with other mental conditions; it is underdiagnosed and often ineffectively treated. This article presents a case of effective treatment with aripiprazole in a 38-year-old female who had suffered from concomitant body-focused repetitive behaviour disorders since childhood. Well-selected medical treatment, an increased patient willingness to undergo treatment, and her motivation to engage in psychotherapy helped improve the patient’s psychosomatic condition and relieve her TTM symptoms
