Thanks ladies for the input!

I'm now determined to switch her to something that hopefully won't irritate her face. Then if she still scratches I'll have to figure it out again.
Anyway, now I guess I just have to decide: do I get a tearless shampoo just to use for her face and continue with the buddy wash/rinse or do I totally switch and use the tearless shampoo for her entire body (and possibly get their matching conditioner, since every line seems to carry the partner products)?
