Barber shops are also places of social interaction and public discourse. In some instances, barbershops are also public forums. They are the locations of open debates, voicing public concerns, and engaging citizens in discussions about contemporary issues. They were also influential in helping shape male identity. In previous times, barbers (known as barber surgeons) also performed surgery and dentistry. With the development of safety razors and the decreasing prevalence of beards, in English-speaking cultures, most barbers now specialize in cutting men’s scalp hair as opposed to facial hair. In modern times, the term “barber” is used both as a professional title and to refer to hairdressers who specialize in men’s hair. Historically, all hairdressers were considered barbers.
