My hot oil treatments leave my hair feeling softer. I use conditioner to "wash" the oil out and it hasn't been a problem for me. I use liquid shea butter/shea oil. In fact, I'm getting ready to do that now. I don't really want to wash it completely out though. Many years ago, I used olive oil and experienced what you you're saying. It was always a pain to get it out and my hair felt very dry afterwards. I've used olive oil recently and I did not have the same problem that I had washing it out like I did years ago. I have no idea why.
