I also use this comb after the leaving conditioner/detangler. Obviously can be any Afro comb but I liked this one cause it’s pretty! https://www.afroanishop.com/collections/accessories/products/afroani-mermaid-semicircle-hair-comb
Coconut oil or avocado oil for the hair ofc and when she gets older there’s avocado oil hair mask 💗
This short wavy hair doesnt need amything really. Just some leave in mixed with water in a spray bottle and mist each morning. Wait and see what she ends up with when.older to know what to use.
What @Gigi L said. Her hair is more on the finer side so it really doesn't need much. Also with curly hair it's important not to wash it too often or brush it dry. I would try washing every 3 - 4 days.
I use this product https://amzn.eu/d/bR1EETp With curly hair you want to lock in the moisture, so you can use that right after washing. I also use the curl defining jelly from the same brand after I’ve combed her hair.
