My hair is fine/low porosity, too. It could be that the products you're using aren't moisturizing enough for your hair. The leave in has denatured alcohol in it. I didn't find the Nature's Gate to do too much for me.
I use minute amounts of really rich products as one of my first two layers in styling. I find that it seals the moisture in. It sometimes takes my hair hours to absorb the products once my hair is dry. Because of this, I never have to DT despite using a lot of protein. My current favorites are in my signature.
