A collection of straight razors are displayed at Alex 'Torreto' Vellios' Torreto barber shop in Frankfurt January 6, 2015. Inspired by a childhood trip to the barbers with his grandfather in Greece, Vellios, 26, a formally trained hairdresser and self-taught barber, fulfilled his dream of opening his own gentleman's barber shop five months ago and has turned it into a successful male grooming and shaving business with customers now waiting up to three to four weeks for an appointment to see him.
