Typical deodorant uses aluminum to help prevent you from sweating. Aluminum is what clogs your body’s sweat ducts and prevents you from releasing sweat. Natural deodorant helps the moisture and odors that come from sweating. When you sweat, the odor develops from the sweat mixing with the bacteria on your skin. Natural deodorants help control that bacteria to reduce the smell, but don’t prevent you from actually sweating.
There have also been many studies done correlating anti-perspirants containing aluminum to an increase risk of developing Alzheimers in life and an increase in risk of developing breast cancer. While the correlation doesn’t mean it will necessarily cause any health issues for you, why take the chance when there are safe alternatives?
I do want to mention that because there is no aluminum, there is nothing preventing the amount of sweat you produce. Sweating is actually a good thing, the body is removing toxins and regulating your temperature. Natural deodorants only help the smell, which in my opinion, is good enough!
