African American & Mexican Baby Hair

My daughter is 13 months old. Her hair is thin-ish, curly/wavy, and dry. When she was a newborn she had a little bald spot on the back of her head. It has grown in but her hair looks so dry there. I’m using Pink Oil for moisture and Castor Oil (my mom told me to use that), but her hair would get dry again. I tried getting her a bonnet and putting a silk pillow case in her crib. Her hair is growing but my fear is that her hair gets dry a lot so it’ll grow slowly. I don’t know what products to use. My husband thinks it’s a waste to get Cantu or Shea Moisture for kids.
