I switched from deodorants with active ingredients derived from aluminum to ones with active ingredients that aren't aluminum based, but those also rated a possible health threat on goodguide.com and other comparable websites. Anyway, perhaps it was preventing a detox of the glands by blocking them from sweating out those built-up aluminum products, because I didn't notice any change in my discomfort.

You should give it a try! I was pretty funky and sweaty for about 2 weeks until all the sudden my underarms dried up and the essential oils helped prevent funk. Perhaps deodorant is a double-edged sword, we start using it to prevent funk, but it ultimately causes intense sweating as the glands try to rid themselves of those toxic ingredients, then we get even funkier and the cycle repeats?

I don't sweat from my underarms much at all anymore, only when I'm being ridiculously active. And if I miss a day of deodorant, I no longer get funky. This is so odd for me, because I was even considering trying a clinical strength deodorant before I completely switched to all natural. It did take a few months for my underarms to completely change. I'm just very happy to have my breasts back.

Oh and no, I don't have a metal sensitivity. less

They associate the aluminum in antiperspirants with breast cancer. My mom had it (she is now cancer free) and the doc told her to go natural now because of this link.

This may have something to do with it.. the aluminum I mean. Maybe it was some sort of reaction to it.

I sweat A LOT. I would love to try a natural one but I am afraid I would stink to high heavens if I did :S less

I've been using natural deodorants (except for special occasions where I do NOT want to be sweating) because of the aluminum materials and the rumored link to cancer.

According to medical institutions such as the American Cancer society though, they have found no 'conclusive' link.

I still prefer to be careful though, in addition to the fact that I just have ridiculously sensitive skin. I switch between a natural crystal deodorant, available online or in Whole foods link and products from this Etsy seller link but she seems to be out of it right now. Her salty dog shampoo is also absolutely amazing, FYI. I've also bought from this shop and liked it link. If you go on Etsy you can search 'natural deodorant' and 'vegan deodorant' and come up with TONS of sellers and just check feedback. less

I do! I actually think it works better than the handcrafted ones, but a. I like the scent of those, b. they moisturize my skin while the crystal has a slight tendency to dry it out, and c. I like supporting artisans and crafters. The only thing you have to remember is that it's just a deodorant - NOT an antiperspirant. You will still sweat when using it, but the sweat has no odor at all. And I tend to use the ones that are actually a crystal that you dampen and then rub on your skin, not the roll-on but I couldn't find a link for that one. My mom uses the roll-on though and likes it. less
