Why are most aftershave perfumed ?

A relative works in the perfume industry, meaning that for Christmas/birthday, I often get a nice perfume that she could buy with her employee discount.

An issue, is that as a person who has facial hair, I shave regularly, and most after shave balm/lotion are scented. They don't even smell that good, but mixing a nice perfume with an after-shave seems like a major faux pas as the smell will interact with each others, meaning that I don't use my perfume as much as I wanted
