If the barbar does not wish to shave, then he does not wish to shave. As was the style in Europe and the United States during the 19th century, it was fashion sense to have facial hair. Those that could not did what they could do...they grew mutton chops. ha ha
Lets examine some:

British gentlemen, victorian era

General U. S. Grant, Commanding General of the Army of the Potomac

General Robert E. Lee, Commanding General of the Army of Northern Virginia, The Confederacy

His Royal Siamese Majesty, King Chulalongkorn The Great, King of Siam

Some Famous Filipino History Figures:
Marcelo Del Pilar, Filipino Revolutionista, Pro Independencia, La Solidaridad

Again, it was the style of the day, and even to this day where there are a variance in facial hair styles. Bare shaven to full grown beard.
