How it works
Swap out your deodorant for plain old baking soda (sodium bicarbonate – not to be confused with baking powder!) and enjoy odorless pits without worrying about what you're rubbing into your skin. Some people recommend combining the baking soda with water to make it into a paste, I apply the dry baking soda directly to my armpits, using my finger tip. It doesn't stop you from sweating (it's healthy to sweat!) but it does leave you odor-free. I recommend storing a little bit in a jar, in the bathroom or your bedroom (ie: where you'll be applying it) as the experience is way more pleasant than sticking your fingers into the full-on box of baking soda.
What you'll need
I've been using natural deodorants for a few years and it seems like they stop working after the first month or so, and I need to switch to something else. My favorite deodorant cream was from Soapawalla Kitchen, but I found it wasn't so effective a few months in (not sure if the product had turned or if my body had somehow adjusted). I went through a phase of using Aubrey Organic's Men's Stock Deodorant Spray, but midway through the second bottle, that seemed to stop working too. Three months ago, I gave baking soda a try (I think I heard about it from someone's Instagram?) and I haven't looked back since. Aside from being cheap and easy to find, it is easy to apply, it leaves me totally odor-free (even after a long day of working followed by a long night of dancing), and I don't have to worry about it being carcinogenic. My boyfriend has been using it too and it works just as well for him.
