Toddler shampoo?

I use a natural baby wash on my 2yo girl (Dr Bronners baby) and she doesn’t have a ton of hair, but lately I’ve noticed some flakes, like dandruff. Also, her hair seems kind of greasy after a few hours. I think the Dr Bronners soap does a good job on her body, but not her hair. Does anyone have a good recommendation for a child friendly shampoo?
