My daughter also has very curly hair which tends to get very dry. I've achieved results by using L'oocitane's olive oil shampoo and conditioner (can be found online or IMAGO BEAUTY GROUP on washington street in Hoboken) I"m not sure if you live near Hoboken or not. Also while you're there you can purchase the phytospecific hair balm again can also find online. The hair balm is best used on wet hair however you should see some results. You can also use carol's daughter products which other friends have used with results.
Good luck
