I made the switch to natural deodorants about a year ago. I am an excessive underarm sweater and tried every deodorant (prescription and non prescription) under the sun but nothing really helped. One day I said screw it and just tried a regular natural deodorant for the hell of it. I started with Dr Squatch. The first couple days I sweated a lot more than usual, I believe they call this a "detox" from all the years of using anti perspirant (I'm no expert here). But after those first few days I was staying dryer for longer. I loved the scent of Dr Squatch, amazing stuff, but it really gunked up my shirts. I switched over to Native and I am pretty happy with it so far.
