I use Montblanc keeps me smelling nice and good all day
I use REXONA for men the black one and this brand is my Deodorant since secondary grade and until now i'm loyal to the brand and never tried using any other brand since then.
I do not use any either, i dont know about any of the side effects that comes with using deodorant but I'm much more comfortable with cleaning and keeping things clean.
Are you sure?you are not using anything underarm ?there is no side effect mate,and besides it added Great smell of freshness .
