Barbershop scents are fresh, clean, almost antiseptic type scents.  Pinaud Clubman is a classic barbershop scent that also has a hint of sweetness.  Classic cologne type scents can fall into this category as well but mostly those that have a "clean and fresh" air to them.  There are going to be a wide variety of opinions on the subject of what, exactly a "barbershop" scent is but for us we include a lot of the classic scents that one might actually find in a barbershop from the soap to the antiseptic to the aftershave and everything in between, all of these atmospheric notes can be included in a barbershop scent.
