Do you use fragrance or perfume? If you do, do you know what's in yours? Ensuring all your personal care (body and skin) products are toxin free is just as important as what you eat.
If you have a particular fragrance you feel you just can't give up, my suggestion is to look at the ingredients and find the notes that you love the most. Then mix up those essential oil equivalents and away you go. If you're sitting on the fence then perhaps take a look at the app @thinkdirty
