I live in a national park and I try to continue to be as natural and basic as possible in whatever I do. For some time now I've been using my bar soap as a deodorant and it seems like it's working out fine - I just rub it under my arms a few times after first using the same soap to wash with. I didn't want to use something with all those chemicals in it anymore and I can save some money too. Of course if the soap you're using has a lot of chemicals in it then you may want to use one that's more natural and or gentler to your skin, like a face soap for example.
