Hope they feel (look) better soon.
Yes, I gave them a bath with the special shampoo and then the next morning I gave them their monthly doses of advantage. I'm thinking that since their skin was clean and free from their natural oils that this may be the reason that they had such a bad reaction.

I know that when people color their hair, it's best to not shampoo first so you'll have some of your natural oils to help protect you. Maybe this is the same with animals and flea products.
