I like to use avocado, bananas and coconut oil as a hair conditioner, occasionally. The rest of the time, I use apple cider vinegar and water.
I'm trying to do the baking soda and water hair rinse, but I need to get a hairband, for the initial oiliness. I've also heard people use castille soap, to wash their hair, instead of shampoo, but I have yet to try this. For now I am simply trying to use less shampoo, less often.
For my face, I use a combination of raw, unfiltered, local honey and lemon juice. Sometimes I add baking soda, or asprin, to exfoliate. I have oily and dry skin, and it helps immensely, and makes my skin soft. Sometimes I use 10% greek yogurt on my face, too.
I also use honey, baking soda, and sugar as a body wash, sometimes with avocado or blueberries and coconut oil thrown in.
I use baking soda on my teeth (but after reading Sabretoothandclaw's comment I might reconsider that), and do coconut oil pulls.
I'm thinking of trying baking soda and coconut oil for deodorant, but I haven't done this yet.
And I don't use lube, or sunscreen, or anything to shave with. But I have read, from people here, that coconut oil can be used for lube and sunscreen, though if you're using it as a lubricant you should check to be sure whatever condom you're using works with an oil-based lube.
I second Sabretoothandclaw's ending statement, that if you wouldn't put something in your body, you shouldn't put it on your body. So I do need to work on my shampoo and deodorant usage, and reconsider my teeth-cleaning choice.
