Most people do not understand fragrance allergies.  Sadly, some who do, don't care.  It is another of those hidden illnesses like fibro that people claim are all in your head.  I wish some folks could spray their hairspray into the back of their throat for just a few seconds....not even the 8 hours I have to deal with it at work and the 12 hour recovery period when I get home.  Maybe they would see this is real, not just something I have made up to torment them.
