Best thing you can do for dry, tangled ends is get a haircut. Only time my fine/low porosity hair tangles is when I use a ingredient it doesn't like.
You should also determine your hair properties. It really helps for choosing ingredients/products. Here's a link to help Live Curly Live Free - Curly Hair Basics
I do at least one PT a week and use a lot of products with protein.
