Candace, an Etsy shop owner at KirkmanKoils has pointed us to a few of her natural hair care products that are coconut-free. I haven't personally tried them because many of them contain mango, which I happen to be sensitive to. But, she could also make custom products.
Her son has severe eczema, asthma, nut/tree nut and fish
allergies. Her daughters are sensitive to coconut; their hair hates it and any
trace of it. She found herself trying to find products to
accommodate their needs while trying to be budget conscious. So she started making basic things like hair
and body butter and eventually moved on to more extensive items like hair
cleanser, conditioner, cream and gels.
It looks like this could be a great place to go for coconut free products, especially if you have super thick, curly hair!
Her shop can be found on Etsy at https://www.etsy.com/shop/KirkmansKoils.

Let me know if you try any! There are a lot of creative hair product ideas here for sure.
