Reposting from the 2 board

I've been using different kinds of natural oils on my wavy hair and i've noticed that they work really well except it makes the last 2 inches feel like straw. i've noticed this with some conditioners as well. I was wondering if anyone had a explanation for this?

My biggest concern is how I can get the rest of my hair to love coconut oil or avocado oil. My hair is 2a from what I've read or at least it seems the closest to it. Should I add something to the coconut oil when I melt it down?
