BFRBs are equal opportunity behaviors that affect both men and women. They are highly underreported and undiagnosed disorders, which oftentimes provides the illusion that women are more susceptible to experience hair pulling, skin picking, nail biting, cheek biting, and other associated behaviors. It is possible that men are less likely to report having a BFRB than women; therefore, present less frequently for treatment. Although research shows that more women likely suffer with hair pulling, it may be that men are just as implicated, but do not report their symptoms.
