Can you ask a provider not to wear perfume?

[Skysue]

I got an email today from a friend with an interesting question, I figured I'd pass it off to you ladies:

Just tell her to let her know it makes her sensative and she gets bad headaches from the smell of perfume & she is worried her son may have a similar allergy.

Just the thought of it is making me feel ill, I get migraines from strong smells too!
