Well, some of the change in your daughter's curls could just be normal for her age - our curls can change with age and hormones, etc. my daughter had curly hair until about three, and now it is mostly wavy with a few curls around her face. But that could change again with puberty!
As far as caring for your daughter's curls, have you considered going CG? You could try cutting out harsh sulfates and silicones to see if that helps reduce the frizz. Most of the products you listed have silicones, which need shampoo to wash out and avoid build up, and shampoo can dry hair out and cause frizz. Also, over conditioning can cause frizz as well. If her hair is fine, this can happen pretty easily.
2c/3a, botticelli/wavy/'swavy (huh?)
fine, dense, normal porosity/elasticity, dry climate
My favorite brands are Curl Junkie, Darcy's Botanicals, As I Am, Curly Kinks and Shea Moisture. Also love sealing with oil and styling with jelly products.
