Simply put, the reason you smell when using natural deodorant is because your body is trying to adjust and change the way in which it works. Normally, when using antiperspirant, your armpits don’t have to do a whole lot to block odor and sweat. Aluminum that is found in antiperspirants will take care of all that, as they block the pores in your underarm area, which prevents sweat from breaking through.
With natural deodorant however, your underarms are now adjusting to a ‘new normal’. They can finally breathe and let out all the sweat and bacteria that has been locked up for years.
Many scientific studies have discovered that when you stop using antiperspirants your underarms begin to overproduce bacteria and sweat for a temporary period. And when there is an over production of sweat and bacteria in the underarm area, it will ultimately lead to unwanted body odor that your natural deodorant won’t be able to cover up. Hence the smell…
Again, this is temporary! This entire process normally takes 4 weeks, and after that, your underarms will have adjusted to the new norm. Now keep in mind that your body chemistry can also affect the duration of your detox. So for some it could only take a few days to adjust, while for others, it could take a month or maybe slightly more.
