Some people recommend doing an underarm detox to get rid of all the accumulated toxins from years of using deodorants with harmful chemicals in them. These underarm detox's use a combination of coconut oil, bentonite clay, and apple cider vinegar to draw out toxins. In my opinion the body is pretty good at doing this, already, but it certainly couldn't hurt to try and get a blank canvas, so to speak. You could also go for a couple sauna sessions or just get really sweaty to expel toxins. In my opinion, the best thing to do is throw out your deodorant with chemicals and try a natural one. Your body knows what to do from there.
