Conditioning question

[sparrowwwww]

 Hi guys! I'm going to deep condition occasionally with olive oil, as per some of your lovely suggestions, but I was wondering the best way to go about it. I tried it yesterday - applied a lot of olive oil to damp hair, let it sit for half an hour, heated it up, etc. But what's the best way of washing it out? Baking soda took forever and in the end, I just used a bit of diluted shampoo on the length of my hair (I know, terrible!)

I think I should just use less olive oil, I got a bit overenthusiastic :P but any tips would be fantastic! :)

Also, do you guys know if cheap ACV is effective? I just bought Safeway brand, and it doesn't seem like it adds shine or anything. I was wondering if it's vital to buy an organic or more quality brand.

Thanks so much guys! I really appreciate your help.
