nexxus humectress (can be used as both wash out or leavein)
nexxus headdress.
You may also want to add to some of the following to whatever product you already have:
Glycerin: a humectant that attracts moisture (NOW Foods 100% pure glycerin, food grade)
Panthenol: a humectant that also adds volume (NOW Foods 100% pure d-panthenol)
Aloe Vera: also a humectant, I think; in any event will help hold moisture in the hair (I like lilly of the dessert or fruit of the earth brands)
