Advice on how to keep a dog I'm allergic to, or should I?

Or not. Or should I? Or not?

sigh.
I am still having reactions to Foxy.
:(

I bathed her thoroughly on Sunday. three whole days ago.
So I don't think that just bathing her often is going to be enough to do it.
It's not like she gives me bad reactions mostly, just enough to be a nuisance.

I seen some spray stuff called AllerPet D.
Has anyone used it and does it work? My husband cried 'snake oil' lol

I also seen some stuff called Petal Cleanse.

I could go the shot route for me, but I think that would be costly, and I doubt insurance would cover that anyway. Also I've read that many times it doesn't work.
so any ideas?
I did also read that bathing the dog in Head and Shoulders shampoo can work for some as it is for dandruff and that is what a person has the allergy to most times. I do know I am also allergic to her saliva because I break out when she gives me kissies. :(
