I have super dry hair and for the past month I started using a coconut oil mixture of:
1/2 tsp coconut oil
1/4 tsp glycerin
1 drop vitamin E
2 tbsp hot water
I mix these together an use it as a conditioner. I rinse it out and it detangles and smooths. Then I put a tiny bit more on after on my ends and my hair is so soft and defined.
Here is an article about controlling curls that addresses dry hair.
