I'm a barber in Ky. I know alot of other barbers who flat out tell people that "they arent allowed to use razors" JUST because they dont want to add the extra service. We are allowed to use razors in Ky. Each state has a barbering board. ( governing body for barbers/ health code, rules and regulations, license.... etc) I doubt a governing board would " discourage using a razor." I would say its against regulations or its not. In each state you can google the states name and board of barbering, get the phone number and ask the board what the rules are.
