How to take care of kinky curly toddler hair

I love when her hair is down but some of her curls get all messed up and looks dry. How do you take cart of it? Her hair is finally growing and I have no clue how to hydrate her curls. I’m mixed but my hair is a different texture and her dad is black. She uses “ curly kids” product line and I absolutely love it. How many times should I wash it? What do people use on “wash day” I’m seriously clueless and don’t judge 🙈
