Okay so I was looking through curly products and here are some suggestions:

Ouidad has a Kurly Kids hair set (includes a light gel, conditioner etc.)
or you could use a low-poo/cowash for her and try using Carol's Daughter hair milk for her- they have a light version and the original- I heard its very good and looking at her hair it sounds absolutely perfect! If your in need of hair washing/care products I would reccomend the Ouidad stuff.

Also why not try a vinegar rinse?
