Share your "crunchy" recipe for soap, toothpaste, shampoo, etc.
I am not really crunchy but know a good bit about skin/hair/makeup. I put canola oil in my hair before washing it at least twice per week.
Oil is basically oil, and since hair doesn't break out, as long as it's not a super heavy oil like mineral oil, it shouldn't make a different what oil you put in your hair. Hence, I skip the much more expensive olive and coconut oils and go straight for the same bottle of oil that I cook with in my kitchen to fill up an old lotion bottle.
