0 relating to people's hair and hairstyles, and to the work of hairdressers (= people who cut and style hair):
This great industry in the last year or two has been lectured and guided by schoolmasters and tonsorial artists, or barbers.
Perhaps you could give me some tonsorial advice later after we have completed our considerations.
It marked the drugstore or apothecary in much the same way as the barber's pole marked tonsorial establishments in some countries.
