I've found a new natural deodorant that is the best out there. It is the "Naturally Fresh Deodorant Crystal" by TCCD International. It contains no aluminum and is naturally fragrance free. Just wet the stick with some water and rub it on.
Of all the natural deodorants I've tried in the last five years, this one stops all odor for hours and hours and hours. I can't believe how good it is. Keep the aluminum out of your armpits. Pick up some and you'll see what I'm talking about. ...................Matt
