Hi. Three months ago, I stopped using commercial antiperspirants and began using a “natural” deodorant. I had profuse sweating for a few days. After that, the deodorant worked well and my armpits felt lovely. All was well for about 6 weeks. At that time, the natural deodorant started to get less and less effective. I had to reapply every 3 hours then last week, I developed body odor about an hour after showering and using the natural deodorant. I read online reviews of deodorants and learned this is a common issue. Many deodorants work for a few weeks then become ineffective. I didn’t want to go back to antiperspirants because it is really bizarre and unnatural to make yourself not sweat. After considering this, I realized that even deodorants that are considered natural are still unnatural. But I didn’t want to smell so I tried an experiment. So far it’s working great but it’s only been two days. For the past two days, I took a shower in the morning, put nothing under my arms and had zero body odor for at least 15 hours. I might be on to something. What I did differently was that I used bentonite clay mixed with water under my arms before my shower. I made a thick mixture of clay and water, spread it on my armpits and let it dry for about 20 minutes. Then I got in the shower and washed it off and showered like I usually do. I would love to know why this works and whether it will continue to do so. Bentonite clay is said to have negative ions that bind with junk like bacteria and viruses. So it may be binding to and removing bacteria from the armpit. My other theory is that it might shrink the sweat glands. I have been sweating the past two days but not very much. I hope you can investigate this and report your findings. I’d love to know the science behind what I am experiencing and I would love the world to know that there is a better way to handle armpit stinkiness (assuming this process actually works for others and continues to work for me).
