They worked well at first for my daughters 3c hair but can be quite drying for her, which then leads to lots of knots. My daughters hair needs more moisture so I use kccc with added olive oil (quite a heavy oil) which keeps her moisturised. I think it'd work better for finer hair like your daughters. I've read your other posts about your difficulties with your daughters hair so I'd use the mixed chicks website if I were you. The founders show you how to not brush the hair after applying the product and how to 'pineapple' as another member suggested on another thread. I would recommend giving it a go by ordering some sample sizes. Her hair looks like the 'perfect candidate' for mixed checks products! x
