This is one of the books to use to guide you, it goes through various body parts (skin, hair, face etc.) and looks at the products people generally use and then suggests home-made alternatives. After that she suggests some commercial alternatives. The edition I was looking at dated to 2002, in the intervening years there are probably some more and less to that list, but it's a good start, particularly if you're in America.
The formulas make me want to get brewing, so it can't be all bad. Seeing as how I've been having skin issues recently it's also timely, as this allows me to determine what I'm putting on my skin.
Overall, possibly a little overparanoid but good food for thought.
