The Natural Deodorant Switch Survival Guide
Why Switch?
Understanding Antiperspirants vs. Deodorants
Antiperspirants and deodorants are often used interchangeably. I used to lump them together too…but they actually work very differently. Deodorants help neutralize or manage body odor caused by bacteria. Antiperspirants do that and contain ingredients, most commonly aluminum compounds, designed to temporarily block sweat glands and reduce sweating altogether.
When you use a deodorant, you will still sweat…and I believe that’s super important.
Sweating isn’t just something our body does when we’re hot or nervous. It plays a role in temperature regulation and supports our body’s natural elimination pathways. When sweat is blocked, that pathway is paused in that area.
Aluminum, Sweat, & Breast Health
What the Research Actually Says
The research on aluminum and breast cancer is mixed and often misunderstood, so let’s talk about what we do and don’t know.
At this time, large population studies have not shown a clear causal link between aluminum-containing antiperspirants and breast cancer. However, some laboratory studies (done on cells, not humans) suggest aluminum may act as a metalloestrogen, meaning it can interact with estrogen receptors in cultured cells.
What we do know:
Aluminum-based antiperspirants block sweat ducts
Sweat plays a role in the body’s natural detoxification and regulation processes
Breast cancer is most commonly found in the upper outer quadrant of the breast, near the underarm
It’s also true that this area contains more breast tissue, which could be a reason to why cancer appears there more frequently.
I encourage you to stay curious, informed, and empowered to make the choice that feels best for your body and family. We’re always here to support you in whatever journey you choose.
Fragrance
Aluminum isn’t the only ingredient worth paying attention to.
One of the biggest concerns in modern deodorants (even many “natural” brands) is fragrance. Products marketed as aluminum-free (like Native or Lume) often still contain fragrance blends. Synthetic fragrances can act as endocrine disruptors, meaning they may interfere with hormone signaling in the body. The tricky part? “Fragrance” is considered a trade secret, so companies aren’t required to disclose what’s actually in it. I personally skip on products with “Fragrance” on the ingredients label.
Timing Matters
When to Make the Switch
I totally understand the excitement of wanting to switch immediately…especially once you’ve bought the deodorant. If you can’t wait, go for it! Just make sure you read the rest of this post so you’re set up for success.
If you’re open to timing it strategically, I recommend starting on a long weekend or when you’re not working. During the transition, increased sweat or odor is common, and being at home can make that phase more comfortable.
I made the switch during an indoor volleyball tournament… and let’s just say I was very aware of my armpits all day 😅
Common Transition Symptoms
The most common reason people give up on natural deodorant is increased sweat and odor. Many assume the product “isn’t working,” when in reality, their body is finally allowed to sweat again…possibly for the first time in years.
Sweat often gets a bad reputation, but it’s essential. Beyond cooling the body, sweating supports detoxification. So if sweat is blocked, are toxins being eliminated as efficiently?
Another common symptom is mild irritation, which can come from:
Baking soda (a very common irritant)
Synthetic fragrance
Certain essential oils
Finding the right deodorant matters. Many newer formulas include skin-supportive ingredients like magnesium, zinc, charcoal, and probiotics to help balance odor-causing bacteria while soothing the skin.
The most challenging symptom I experienced personally was a sweat rash. Constant moisture led to irritation. Looking back, I would’ve:
Taken breaks to wipe my underarms
Worn more breathable clothing
Packed extra shirts just in case
Supporting Your Body During the Detox Phase
You can be both annoyed by the sweat and grateful for what your body is doing.
To support the transition:
Use a charcoal or clay mask on your underarms to help draw out impurities
Long-term, once weekly or as needed works well
During the initial switch, you may use this daily for a few days
Support detox from the inside out with:
Clean, Whole Foods — A highly processed diet increases the toxic load your body needs to eliminate. This could cause more odor during this phase!
Plenty of water + minerals
Optional support like chlorophyll and probiotics
Final Tips for Success
Less is more when applying natural deodorant
Don’t hesitate to reapply throughout the day
Wash your underarms nightly to reset bacteria
Use detox masks as needed
Your body is incredibly intelligent…sometimes it just needs space to do what it was designed to do. ❤️
Products to help the transition…
Here are some products I have used and loved. I am always honest with the products I recommend and if I haven’t used them…I let you know!
Rowe Casa Stick Natural Deodorant
Affordable. Doesn’t leave the white stain on t-shirts! You have to find the right smell for your body…I love the vanilla mint smell, but it didn’t work on me. I am not a fan of grapefruit bergamot on its own, but I LOVE it as a deodorant. This deodorant also glides on..unlike the Schmidt’s brand I have tried in the past. NO artificial fragrance either. We sell this one in our office. :)
Great for on your face or under arms. It even comes with a cute spatula to use. We usually keep this one on hand in the office for our patients making the deodorant switch!
Thorne Complete Biotic
Our favorite probiotic to recommend. It’s so easy on the gut. But what works for me might not work for you, but this has been a winner in our office for patients and generally the first probiotic we suggest. It’s an a convenient packet form and powder…so know pills, water, or refrigeration needed. SO convenient for traveling.
To order, join our fullscript dispensary! Or message us and we will add you to our next Thorne order.
For hydration during the sweaty detox stage. We love our LMNT packets in the office. We always give a discount when you purchase them in the store!
