I have heard about using olive oil and I tried it but it didn't act like a soap... I tried extra virgin coconut oil too and it does work well for many things but when I tried to use it as a "soap", it was a slimy mess lol... I'll have to try the olive oil again. Coconut oil works great as a conditioner and it doesn't oxidize or turn rancid. Maybe I'll try mixing baking soda with oil...
