All the organic coconut oils I've seen are also virgin coconut oils. Hardly seems worth it growing organic coconuts and then making refined oil out of them. You can get virgin organic coconut oils from iherb.com for cheap (if you've never ordered from them, you can get a $5 discount, just send me a PM).
For your hair, it likely doesn't even need to be organic; it has to do with the fatty acids and not the other stuff that is in virgin coconut oil.
