People are attracted to other people for very particular reasons. Often it has nothing to do with beauty (of some kind of absolute sense). I know some people who find me more attractive when I have a beard and others who find me more attractive when I'm beardless. Same clothes, hair, smell, personality but it can simply come down to whether they find bearded/non-bearded me more attractive.

The spray could have be a "see what you want to see".
