Shampoo for eczema

Hi Ladies, my daughter has mild eczema which I control with Advantan when necessary. I wash her with Epizone E and have been using it as shampoo as well, but her hair is getting too long now and the Epizone E makes it greasy. I've tried Johnsons because I had it in the cupboard, but her scalp started itching terribly, poor thing!

Any suggestions on what shampoo I can use?

Also, what about foam bath for sensitive skin?
