I listen to the Joy the Baker Podcast from Homefries.com. Its pretty fantastic.
One of their episodes was about hippie-ness. They talked about home beauty remedies including using coconut oil for conditioner and using baking soda for shampoo. I went home and promptly used it as well. It makes your hair super squeaky clean. Literally, squeaky.
Bottom line of this story is I've only done it once. I'm not hooked yet, but may try it again.
