Finally have a tried and true homemade deodorant recipe that works for me! I can't believe it. The search may actually be over! It's been a month or so now with it and it is perfect: no skin irritation at all and no body odor. Surprising since it's made with such simple ingredients. I didn't even need arrow root, corn starch, or baking soda and it still works great! Amazed. Link here.
I have mine in a glass jar and it works fine by just scraping a bit out on the top of my finger, though this recipe I believe would lend itself nicely to a stick since it solidifies.
