a lot of times people avoid products that have mineral oil in them because not only does it seal moisture from getting out, but it also seals moisture from getting in.

not sure what type of hair your daughter has, but hopefully you can find sucess with the kinky curly products. around the time my oldest was 1.5 or 2 is when i tried to start looking for products that would work for her and she's been using knot today and the curling custard ever since (she's 4 now). she has very fine, relatively thin, 3a/b hair and i've yet to actually achieve 2nd day curly hair with her.
