My boyfriend sweats a lot and uses Mitchlum deodorant, a lot of it, under his armpits and waits til it dries to stop the sweating. I heard aluminium was bad for you, but he says natural deodorants don\'t work as well. What do you think?Aluminium is bad for you and too much aluminium can cause Alzheimer\'s disease and other problems. External deodorants are displaced by your perspiration and don\'t last long. Liquid chlorophyll is an internal deodorant that deodorises your body odours and perspiration odours before they come out of your pores. A table spoon of high strength liquid chlorophyll every day is all you need. Liquid chlorophyll also has a cooling effect so you perspire a bit less. You can find further information in a search for liquid chlorophyll + deodorant.This is doctrine according to me, so Don\'t take it for absolute truth. I had a science teacher who said the aluminum in deodorant was bad for you because you have major arteries in your armpits that go to the rest of your body and it carries it there and is linked to things like alzheimers (please excuse my spelling). Then I had another teacher who said that that was complete rubbish. Aluminum is everywhere. If it was going to do that from deodorant, it would do it from a million other things. Oh, and certain deodorants work for certain people, others not so well. I actually have to switch types every once in a while because the one I use stops working. In my experience, the natural stuff doesn\'t work as well. So, you don\'t have to believe me, but you asked what I thought.different styles and types of deodarants work on different people experiment on lots of deodarant and see which one where u can not use to much but is still petty effectiveOther related question
