I must disagree. I developed a terrible allergy/migraine trigger to scent.
I used to wear perfume when I was younger, and I do miss it a lot. I have to use scent-free dryer sheets, laundry soap, etc. Otherwise ,I get terribly congested and am left with a headache to die for, which can go on for more than a day.
Mind you, I can handle gasoline smells, car exhaust, and cigarette smoke with no problems.
It ia terribly difficult to bring up people, but I manage to do so. I've never had anyone get upset with me.
And I too have learned the art of not breathing when stuck in an elevator.
BTW - the amount someone is wearing isn't indicative of anything. At one client, I was getting bad headaches every time I talked with this one woman who never wore perfume. I mentioned it to her one day, she pulled out some scented handlotion I could barely smell, and my headache kicked in. The next few days, she didn't put any on, and there was no headache. So, it's the molecules in the air that enter your bloodstream, not necessarily what you can smell. I have to say that as I get older, I am starting to be able to tolerate some scents, but it is slow going.
I am blessed to have only 1 allergy that I know of and I don't have to use the product. I really feel for the suffers of nasty allergies and if I know of it, I will do my best to help avoid the cause.
