I switched to a healthier deoderant. No aluminum (I stopped using antiperspirant years ago), no parabens sls you get the idea. But it just doesn't work to my standards which was set by old spice. I felt clammy and funky within hrs. Now I use witch hazel that I poured into a spritzer and hit my underarms after shower before applying the deoderant. No more funk. I figure it sets the ph to levels where bacteria won't grow.
Ps the deoderant contains witch hazel as an ingredient to begin with.
