Is it true that other people’s fragrances can cause allergic reactions.

Among the many things I try to cram into my schedule is a newsletter for people with sensitive skin. I am not very successful at doing this I am afraid, and I don’t get the newsletters out very frequently. But despite this I get a steady stream of people talking to me about their issues
