Pros: works great, super-green, fair trade, yummy "flavors"
Cons: the peppermint can be a bit brisk!
So theoretically you can get 18 uses in 1...but why would you stop at 1 Dr. Bronner's?
Here's what I like different "flavors" for:
Tea Tree (new-ish): nice body wash in the summer, leaves skin smooth and clear. Good face wash too. Just be careful not to get it in your hair--it's really dries it out.
Peppermint: It's definitely invigorating! Good for winter showers, because it helps your blood get flowing. But careful on sensitive areas!
Lavender: This is my personal favorite--I use it as a body wash and bubble bath, and it works well as a hand-wash detergent for my delicates. Supposedly you can use it for shaving, but I find I definitely need moisturizing lotion afterwards when I've tried it.
Citrus: I like this one best for hand-washing, and it's a good for guests. Everyone likes the bright scent of citrus! This is the only one I've used (diluted) as a cleaner. It worked well on grease.
Unscented/baby: Good for washing pets. Probably good for washing babies too, but I haven't tried it ;)
