I've used Tom's of Maine deodorant and toothpaste and both have worked for me. Switched to Alba Botanica <another "natural" product> for deodorant because it ended up costing a little less. What i have is Alba Botanica "clear enzyme" un-scented with aloe and baking soda. hypoallergenic...product from Hain Celestial Group.
I usually use it once a day unless I take a shower mid-day after intense work-out, when I would re-apply-
times? maybe two or three swipes
last? all day, usually <see above>
type? translucent roll-on
years? maybe a year
change? not usually
