I Tested 16 Aluminum-Free Deodorants to See Which Ones Actually Worked

I Tested 16 Aluminum-Free Deodorants to See Which Ones Actually Worked

Compare Our Top 10 Natural Deodorants

More Natural Deodorants We Tested

Kopari Performance Plus Deodorant for $20: This deodorant smells great—like a floral, beachy coconut. It’s more fresh than sweet, and I’d say it’s unisex-leaning-feminine. It goes on clear and smooth, and it didn’t stain my clothes at all. However, it didn’t last me through a workout without reapplying, unlike some other brands I tried. I think it’s fine, but I wouldn’t call it a “performance deodorant.” If you’re looking for a clear formula and you don’t mind reapplying, it might be worth a shot.

Fur Ingrown Deodorant for $19: My relationship with this deodorant is as complicated as my relationship with my underarm hair. Sometimes I don’t shave it for months; sometimes I shave it every other day. This deodorant contains ingredients like willow bark (to prevent ingrown hairs) and niacinamide (to brighten underarms). It did both of those things very well. But it didn’t do a great job at preventing odor throughout the day, and the smell is very green and earthy, which didn’t agree with my body chemistry. It might really appeal to some people though—online reviewers seem to love it or hate it—so I recommend smelling it in a store before purchasing.

Curie Clean Deodorant (two-pack) for $28: This formula smells good when first applied, but quickly fades away after an hour or two. It also stained my clothes more than some others I tried. During my second use, it caused some irritation, so I discontinued it. I didn’t notice myself sweating more or less compared to other kinds of natural deodorant. However, the brand does have a great Detox Mask that can help with the transitional period when switching to natural deodorant. It’ll be featured more prominently in an upcoming guide.

Dove Aluminum-Free Deodorant for $11: Dove’s deodorant is mostly fine, and I like how affordable it is. But the texture is really smooth and leaves my underarms feeling strangely sticky, even after letting them dry. The fragrances aren’t powerful or long-lasting enough for my own personal preference. They also all have a powdery undertone that I was not a fan of. I did notice some BO partway through the day during my testing. Since this is so subjective, your mileage may vary. The packaging also came taped shut, and the tape left behind sticky residue on the outside of my deodorant that was impossible to remove without rubbing alcohol.

Lume Whole Body Deodorant (three-pack) for $40: This pricey deodorant smelled terrible to me. I received the Invisible Cream formula in Minted Cucumber, which smelled like pool chlorine and hand soap. I refused to put it on my body. I also received the Clean Tangerine Smooth Solid formula, which initially smelled marginally better but still had a weird hand-soap element to it. It left white marks all over my clothes and oddly smelled like cheese once applied. I washed it off and called my testing done. Reader, I love you, but I’m not going to smell like cheese all day just to see if the smell magically transforms after a few hours. Senior commerce editor Kat Merck also tried the Lavender Sage Invisible Cream, and she said it reminded her of laundry that was left overnight in the washing machine—and that the deodorant made her smell worse than she would have had she not worn any in the first place. Lume does have many fans across the internet, so again, this may be something that can be boiled down to personal preference. I suggest smelling it in a store before purchasing.

Bite Refillable Deodorant for $44: I like the minimalist aesthetic of this refillable deodorant. The sleek metal case is almost miniature, and the entire setup is completely plastic-free. However, it’s easy to push the deodorant stick up too high, which can be messy if the temperatures are warm. In fact, I found the formula too soft in general, and it tended to get gunky and gummy throughout the day, both on my armpits and on the case. I also didn’t love the neroli scent. I think this could work well if you want the most minimalist, nondescript natural deodorant possible, but there are other refillable options that smell better and last longer.

Saltair AHA Deodorant for $12: I was initially really impressed by the scent I tried from Saltair. Pink Beach smells like a summer sunset on the ocean. Unfortunately, despite my best efforts to make it work, I couldn’t apply this formula without my armpits feeling sticky and irritated. I used it on clean, dry, hairless skin, and I let my armpits dry fully before lowering my arms. But I had this constant feeling of tacky, sweaty irritation that eventually led to a rash, so I discontinued testing.

How Does WIRED Test Natural Deodorants?

I‘ve been wearing natural deodorant since 2020. I wore each of these deodorants at least seven times—including at least once during a calm day at home and at least once during a workout at the gym. I also tested whether they stain by putting on a black T-shirt after application. I test each on freshly showered and shaved skin, and by reapplying it at least once on a day that I haven’t showered. Next I’ll be testing liquid AHA deodorants and aluminum-free deodorant from Schmidt’s.

What Ingredients Make Natural Deodorant Work?

Here’s an explanation about some of the ingredients you may see in your research.

Aluminum: Natural deodorants (usually) mask odor and don’t emphasize sweat reduction. Antiperspirants (usually) mask odor and prevent sweat. The sweat prevention comes from aluminum salts, which block sweat ducts under your arms. There were a few studies that talked about elevated breast cancer or Alzheimer’s disease risks from using aluminum, but there’s no definite link between them (according to the FDA, the American Cancer Society, and the National Cancer Institute, among others). It’s probably fine to use antiperspirants with aluminum in them. Some people with kidney disease are advised to avoid aluminum, and others want to “play it safe” and avoid aluminum. As for me, I sort of feel better when I sweat? In any case, that’s the lowdown on aluminum. TL;DR: The science says it’s fine for most people.

Parabens: Parabens are preservatives that have been shown to mimic estrogen in the body, but at much lower rates than the body’s natural estrogen. Parabens are somewhat common ingredients in food, medicine, and beauty products, though they’re less common as more people try to avoid them. Some parabens are banned in the EU until more research can be done. The FDA has concluded that parabens are safe. It’s relatively easy to avoid parabens if you choose to. Most antiperspirants don’t contain parabens; most natural deodorants don’t, either.

Phthalates: Phthalates make plastic more flexible and durable, and they can also be used in some beauty products as stabilizers. Some studies have concluded that they’re safe; others suggest links between phthalates and skin irritation, cancer, or early death. But those links were not causal. Phthalates do have a California Proposition 65 warning. The recommended deodorants in this guide are phthalate-free. Many antiperspirants do contain phthalates, but not all of them.

Baking soda: Some natural deodorants use baking soda as an absorptive agent to prevent sweat and as an antibacterial agent to prevent odor. Some people can develop a rash from using baking-soda-based formulas, due to the reaction between the baking soda and their body’s natural pH balance. It’s hard to tell whether or not you’re sensitive to baking soda until you try it, but if you typically have sensitive skin, you may want to try a formula without baking soda. (We recommend some in this buying guide.)

What Is the “Transition Period”?

When you make the switch from antiperspirant to natural deodorant, you might go through a transition period lasting from one to four weeks. Long story short, after years of not sweating while using antiperspirants, you might find yourself sweating a whole lot more as your body adjusts when switching to natural deodorant. It’ll level out eventually, but for me personally, I smelled like a gym full of teenage boys for two weeks. Some people don’t have a transition phase at all. I also developed a heat rash from sweating so much during the middle of summer—my skin was irritated, which meant I couldn’t use deodorant at all, therefore raising the Stink Factor. Now, though, I sweat less than I ever did while using antiperspirants.

Be prepared to stick it out. I have an issue with the term “detox,” because our bodies already have a detoxifying process (called the kidneys). However, a clay mask like the Curie Detox Mask can be helpful in drawing out excess moisture and calming down irritated skin that you might experience during the transition period. Otherwise, just keep your underarms dry and be gentle on your skin. It won’t last forever.

What the Tables In This Guide Mean

It’s hard to empirically test deodorant. Scent preferences vary from person to person, and they can change based on your body chemistry. Some people might prefer a different formula, some people shave and some don’t, and some people care more about sweat absorption than scent. Do you shower every single day? Do you work out frequently? Do you naturally sweat a lot or a little? All of these things can factor in to whether or not you’ll like a deodorant. Here’s what the tables in this guide mean.

Available scents: How many scents you can choose from as of press time.

Free from: These ingredients are not in the deodorant.

Scent strength: “Strong” lasts all day. “Medium” fades halfway through the day. “Faint” means it faded fast or was barely noticeable in the first place.

Sweat level: “Low” means I didn’t notice any sweat. “Medium” means I noticed some wetness but didn’t feel the need to reapply the deodorant. “High” means I sweat a lot and felt the need to reapply throughout the day.

Clothing stains: “None” means it didn’t stain my clothes. “Few” means it might show up on a black T-shirt. “High” means it will absolutely show up on your clothes, regardless of color.

Functional ingredients: A list of the main ingredients that help absorb sweat and prevent odor.

Formula details: Is it vegan? Is it a stick, cream, or roll-on? I’ll let you know here.

The AI revolution we’re all living through has shaken up the labor market, supercharged the stock market, and flooded the internet with memes, but you may not have noticed that it’s quietly rewriting the rules of online dating. 

Large language models (LLMs) have put the power of sophisticated chatbots into the hands of ordinary people, including ordinary scammers, leading to a massive surge in fake profiles and bots taking over dating sites. Now, online dating isn’t just about being witty or taking a great selfie; it’s also about spotting AI-generated writing or photographs to avoid being scammed every other match. 

These same AI tools have made it much easier and more affordable for dating apps and sites to enforce their moderation policies, and some of the apps have even harnessed AI to improve quality of life for their users, either by refining the matchmaking or by acting like a digital wingman, suggesting which of your photos to showcase or picking out new profiles for you based on your past matchmaking preferences. That being said, AI has also led to more sophisticated trust and safety features from dating apps, like how Bumble uses AI to weed out spammers and scammers. These apps are also using AI in user-facing features, including acting like a “digital wingman” and helping you improve your profile.

Hookup apps for everyone

AdultFriendFinder readers’ pick for casual connections

Tinder top pick for finding hookups

Hinge popular choice for regular meetups

Suspicious of AI, or just want a break from our digital overlords? Here are three hookup apps that haven’t yet succumbed to the AI revolution.

3 hookup apps without AI features

Feeld

Billed as a “dating app for the curious” and the place “where curiosity meets connection,” Feeld is easily the most open-minded app in the hookup sphere, a place where you can find anything you’re looking for and even things you didn’t know to look for. From the beginning, Feeld rejected the algorithm-based swiping frenzy that became the standard on so many other apps, preferring to treat its digital space like an online house party where you might talk to anyone who catches your fancy. 

As of this writing, Feeld has not yet embraced AI, and if its CEO is to be believed, they don’t have any plans to, either. 

Pure

Pure, the “open-minded dating app,” is definitely built around short-term fun, with an emphasis on anonymity and prominent displays of “turn-ons” and kinks, but it also bucked the carousel-style matchmaking trend made popular by Tinder.

There are two main ways to connect with strangers: you’ll either be shown one profile at a time, forcing you to properly assess each person for compatibility, or you can opt for the “Devil’s Bones” gamble, which puts you into an anonymous voice or text chat with a total stranger.

If you’re sick of the indirect approach of most dating apps and want to avoid AI’s influence in the algorithms, Pure is a great, straightforward alternative.

AdultFriendFinder

If you’re really anti-AI, you’re probably safest sticking with AdultFriendFinder, not because it has any ethical or philosophical objections to artificial intelligence, but because its site architecture has hardly changed in the 25+ years since its founding. 

Even better, AFF doesn’t have an algorithm-based matchmaking system. Instead, it allows you to search for people based on criteria like their location, gender, age, or favorite kinks, or else it creates online communities and discussion boards where you can meet like-minded people to start conversations organically.

If you don’t like the idea of artificial intelligence impacting your future hookup options, the above three apps and sites are a great way to resist the tide.

I’ve seen lots of so-called “smart” bike locks over the years, but none so far could justify the added cost. A newcomer that got its start securing ATMs for banks is trying to change that. There’s nothing wholly unique about the TMD Chain Lock, but the combination of materials, performance, and insurance-friendly ART-2 certification makes it worth considering.

TMD’s first bicycle lock combines a Bluetooth proximity sensor and motion alarm with a slender core of hardened steel chain wrapped in a soft and lightweight sleeve of high performance Dyneema and Kevlar fibers. That makes this lock tough, yet flexible enough to conveniently wrap around your seat post when cycling. TMD also designed the keyless lock to be shareable with friends and family, and capable of withstanding shock, rain, dust, and extreme temperatures. That makes it highly suited to city bikes parked outside and ridden all year long.

I like the TMD Chain Lock I’ve been testing, but spending €249 (about $283) on something that typically costs far less is a big ask.

$280

The Good

  • Strong yet flexible lock won’t scratch bike
  • Digital key can be shared with friends and family
  • Convenient if you lock your bike several times a day
  • ART-2 certified for insurance
  • Loud enough alarm

The Bad

  • Very expensive
  • Lacks USB-C charging
  • Annoying operating sounds

The chasm separating ATM security from bike security isn’t as wide as it might seem. TMD developed a centralized, keyless system for banks to authorize access to its ATMs for service, replacing the physical master keys that created a massive security risk whenever they were lost or stolen. It’s this same keyless knowhow that TMD now brings to the Bluetooth bike lock.

There are many advantages to turning phones into digital keys, especially in bike-centric societies like the Netherlands, which TMD calls home. For example, I could ride to the train station and have an authorized friend pick the bike up later. And the keyless convenience quickly adds up for those of us that use our bikes to commute to work, pick up the kids from daycare and football, run errands, and shop for groceries. In my home city of Amsterdam, it’s not unusual to grab my keys more than a dozen times a day to lock and unlock my bike.

I tested the TMD Bike Lock in the 110cm (about 3.5 feet) length with an iPhone 15 Pro running the latest version of iOS. Generally — I’d say 19 out of every 20 attempts — the TMD Chain Lock immediately recognized my approach, allowing me to seamlessly unlock it with a push on the lock’s only button. When I did have to wait, it took no more than a second for the button to flash blue, indicating the lock had detected my nearby phone in a pocket or bag. Pretty good, but that convenience comes with some tradeoffs.

The bike sat unlocked across the street since it was still within Bluetooth range of my phone at this cafe.

My bike, parked outside this window, would automatically unlock whenever I cooked.

Charging the lock off my laptop. It’ll also charge off a phone’s USB-C port.

Don’t lose this proprietary charging cable!

For example, my bike remained within range of my phone when parked outside a cafe, so anyone could have walked up and unlocked it. I had the same issue when cooking in my kitchen with the bike parked just outside the window, as I normally do. In both cases, I either had to move the bike or turn off my phone’s Bluetooth radio. And since my phone is now my bike key, if it’s stolen, my much more expensive e-bike is vulnerable as well.

TMD says its Chain Lock is “immune to conventional drilling and picking,” but all bike locks can be defeated by a determined thief. The Chain Lock has earned an ART-2 certification issued by an independent Dutch organization that tests and certifies bike locks on a scale from one to five. Most Dutch insurance companies require ART-2 at a minimum to validate policies on expensive e-bikes and cargo bikes. It’s akin to something like a Sold Secure Silver or Gold rating in the UK, a 2 Roues in France, and VdS approval in Germany. (The US and Canada do not have a single, centralized, independent testing body that dictates insurance requirements for bicycles.) Should your bike be stolen, you can produce a digital log file for the insurance company from within the TMD app as official proof that your bike was locked.

To deter theft, the lock also features an integrated motion alarm that can be armed and disarmed in the app or with a double press of the lock’s button. At 100dB it’s less shrill than I expected, but it does the job when it senses the lock being jostled. It shuts off automatically after about 10 seconds of inactivity.

TMD tells me that a future software update will let you disable these sounds.

The lock is rather noisy in day-to-day usage. Unlocking it is accompanied by a loud tone that hits 75dB when measured at a distance of one meter. I hate that it draws attention to me and my expensive e-bike. Just flash green and unlock — that’s more than enough. TMD tells me that a future software update will let you disable these sounds.

TMD claims the lock’s battery will last up to nine months on a single charge. However, my test unit has already dropped 16 percent after a week of testing, suggesting a lifespan closer to six or seven weeks. But that’s likely because I store my bikes inside my house when not in use, so the lock’s Bluetooth radio is constantly being lit up by my phone’s proximity.

To prevent water and dust ingress and leave more room for the battery and speaker, TMD says it opted for a shallow magnetic pin connector – not USB-C – to charge the Chain Lock. That’s a shame because plenty of phones have USB-C ports and offer even better IP68/69 protection against rain and debris. That means you’ll need to have the lock’s proprietary cable on you should you ignore the low-battery warnings and let it die. It can be quickly recovered, however: I saw a completely dead (and locked) Chain Lock spring back to life after just two or three minutes of charging off the USB-C port of an iPhone.

You can still unlock the TMD Chain Lock should your phone die. You just have to tap in your four digit “emergency code” on the lock’s button. Choosing a code like 1324 would require 1 push, then 3 pushes, then 2, and 4. The ring around the button changes colors to visually prompt you for each new number. The TMD app also lets you share the lock with friends and family, who can also come to your rescue with their own phones.

100cm is my preferred length.

For added peace of mind, it’s always a good idea to double-lock your bike, so most urban cyclists combine a chain lock with a ring lock that’s permanently mounted to the frame and prevents the rear wheel from spinning. TMD has already announced an “anti angle grinder” U-Lock and GPS-equipped Ring Lock coming later this year. Having my phone unlock both of my bike’s locks simultaneously would really up the convenience factor and better justify TMD’s pricing.

Right now, paying €249 when equivalent analog bike locks costs a quarter of that would be foolish for most people. The ART-2 certified ABUS 8900, for example, in the same flexible 110cm length, costs around €60 (about $68). If you can afford the TMD Chain Lock and really hate keys, or need a keyless lock that can be shared digitally with others, then have at it. Otherwise, it won’t justify its exorbitant price.

  • Strong yet flexible lock won’t scratch bike
  • Digital key can be shared with friends and family
