Details

We formulated this powerful underarm primer to transform any natural deodorant into extra-strength protection that prevents odor and removes deodorant residue.

Did you know that BACTERIA + SWEAT = ODOR?

The main cause of odor is actually bacteria. They grow and thrive on parts of your body that trap moisture, like your armpits. It is key to eliminate odor-causing bacteria on your skin before applying natural deodorant. Without bacteria present, you will not experience smelly armpits. Showering with the underarm bar eradicates any bacteria in the armpits or trapped in body hair.

the underarm bar targets and neutralizes odor-causing bacteria, and enhances the power of your deodorant by creating a protective barrier against bacteria.

Formulated with 3 key odor-eliminating ingredients:

Apple cider vinegar (highly effective at targeting bacteria)
Activated charcoal (highly effective at neutralizing odor)
Sodium chloride (highly effective at targeting odor causing bacteria)

IMPORTANT

Maximize the bacteria-eliminating power of the underarm bar by massaging the lather in the underarm area for at least 30 seconds on each side.

The underarm bar can be used as a standalone deodorizer. However, for optimal odor protection, we suggest that you use it in conjunction with a deodorant with a powder barrier to absorb moisture.

HOW TO USE

For best results, use the underarm bar prior to applying your natural deodorant.

Moisten the bar with water, and create a lather in your hands.

Apply lather to the underarm area in a circular motion for 30 seconds.

If you have body hair, ensure that you are massaging thoroughly and the lather is reaching the surface of the skin. Note it can also be used on feet to eliminate odor but not recommended for other body parts.

IMPORTANT

In order to eliminate all traces of odor-causing bacteria, you must massage the lather into your armpit area for at least 30 seconds each side. The longer you massage and leave the lather on, the better the protection.

After rinsing off, pat skin dry before applying your favorite natural deodorant. 

For optimal results, use daily with the takesumi detox® charcoal deodorant as they were formulated specifically to offer extra strength protection together.

    I love this product! The Underarm Bar is effective for underarm odor. It also leaves my face smooth and corrected the acne on my face.

  2. Tiffany Adams (verified owner)

    Best bar ever! This works perfectly. I had bad underarm odor and it is practically gone since using the bar (and deodorant too!)

  3. Jana (verified owner)

    I can’t believe it really works. I kept me from sweating and didn’t irritate my skin.

  4. Aman (verified owner)

    Wonderful product that works! Follow the directions and you’ll no longer have that “my natural deodorant isn’t working anymore” moment. I recently was without my underarm bar for about a week (travelling – must buy travel size!!) and could actually feel the build up of product that was stopping my deodorant from being as effective as it could be. If you want clean ‘pits’, you need this bar!!

  5. S. Vince (verified owner)

    I love this product and do think that it helps keep the odour at bay.

  6. Rebekah P (verified owner)

    We absolutely love this bar. Always takes and keeps the body odor away.

  7. Nicolette Nicoletti (verified owner)

    I absolutely love this soap! It works well, leaves me smelling nice and makes me feel very clean!

  8. Alexandra

    Using this soap definitely helps to boost the power of the deodorant. I would highly recommend using this along with your natural deodorant.

  9. Lindsay

    I LOVE this soap! Was never a fan of bar soap, but this feels different – and since switching to natural deodorant and trying to limit plastic, this is an amazing solution. Both my man and I use it and my only bone to pick is that you don’t make a bigger size!! Please make a full size bar, this one only lasts us about 3-4 weeks for 2 people (and we’re not even showering every day).

  10. Jelong87 (verified owner)

    I’d like to start by saying that I do not find that this works for me to allow me to use natural deodorant. My body is a little sweat and stink machine, and over the past several years even with prescriptions unable to stop it, the doctors and I have determined that it’s just one of the things my chronic illnesses work together to create. So I still use aluminum deodorant, unfortunately.

    HOWEVER, where this bar does perform spectacularly is in my inner thigh area (female). I get large cysts and other bumps there that were diagnosed as a skin condition that is exacerbated by my chronic illnesses and was told there is no fix for. These bumps range in size, but are often very large, very painful, and due to clothing rubbing on them (I’m uniformed at work so I don’t have options), they leave horrid scars. Suggestions I received were “try this medication with 8,000 side effects and no actual proof of it working for this” or “have you considered not wearing pants”.

    One day, on a whim, I dug this bar out and started using it in my inner thigh area and within a week the bumps were going down and we’re far less painful. I get a good later on my hand, apply, and let it sit for a minute. MIRACLES. Now I don’t get nearly as many bumps, and the ones I do get are typically smaller, go away faster, and for the most part aren’t leaving scars!!!

    Anyone with a skin condition that doctors can’t fix should try this bar! I also use it after particularly hot days to ensure I don’t break out where my bra sits. Fabulous!

    Thank you for sharing your very interesting and unique experience with the underarm bar. We are thrilled to see that you’ve found a different use of the bar that most benefits you! We have definitely learned something new from you! 🙂

  12. Mindy B (verified owner)

    This soap and the deodorant have been a game changer for me. They work better together than conventional antiperspirants ever did. The soap smells so good and it really keeps me dry and fresh. It’s quite amazing.

  13. kaia naturals (verified owner)

    Hi Mindy! We are so excited to hear that you’ve been loving the combination of the deodorant and the underarm bar! Thank you for sharing your thoughts!

  14. Valeria Betancur (verified owner)

    Love this product!

  15. Keiki Jacobs

    This soap is a godsend! Thank you kaia!
    I really love it, it will leave some black residue FYI, but pretty easy to clean if you clean your shower regularly.

  16. Savannah (verified owner)

    The underarm bar is a game changer! Even if you forget deodorant but still use the under arm bar it helps you keep fresh! Paired with the juicy bamboo deodorant and it’s the perfect combo 🙂 I used to have such a hard time with finding a natural deodorant that works! I’m so happy finding kaianaturals!

  17. Madeline (verified owner)

    I’ve been using this soap for my underarms since I got it and I am in LOVE!! I first found out about Kaia through @wifelife on Youtube. I never fully understood why natural deodorants did not work well for me, but it’s because we have to detox all those years of using toxic common deodorants. I have used this soap and have noticed dramatic improvements in my natural deodorants performance. Wonderful product, definitely will repurchase.

  18. Layla Jacobs (verified owner)

    This soap really helps with odour and compliments the deodorant.
    I had a bad reaction to a deodorant with baking soda but this deodorant has been good and I’ve been using it for a couple of months.

  19. Tim (verified owner)

    Love this product! Won’t use any other soap.

  20. Anya (verified owner)

    This soap is so so nice, love this product.

  21. Tiffany

    The ONLY thing that keeps me fresh! Since moving to the southeast, my BO has gotten out of hand and nothing helps! Everything breaks me out in a rash and I smell bad…through my clothes. This bar and the matching deodorant changed the game!

  22. Kim Czotter (verified owner)

    I am so incredibly greatful for this bar!!! I had rashes under my armpits for the past 2 years that were insanely uncomfortable and unsightly. I tried multiple creams prescribed by doctors and tried not wearing deoderant, switching deoderants and exfolitation. Nothing worked. Within 2 days of using this bar my rashes were GONE. i used it for one week straight and then stopped just to see what would happen – they have yet to come back 6 months later.

  23. kaia naturals (verified owner)

    We are so glad to hear you haven’t given up on natural deodorants and that the underarm bar has been working for you, Jess! Keep on it, and your body will surely fully adjust to it soon. Thank you for letting us know your thoughts!

  24. Jess

    After having issues switching to natural deo for 2 months, even though my soaps don’t have SLS in them and are natural, customer service told me to get this bar soap. I used it a few times, I don’t use it every day as I don’t shower every day unless it’s necessary (smell, sweat, was out and about a lot, etc.), I wasn’t seeing much change. But after using it maybe a total of 5 times whenever I do shower, I noticed a huge difference. I will still kind of get stinky at times but it’s not overwhelming and only I can smell it, it wasn’t like it was before. So I’m pretty sure as I continue to use this, it will only get better and if you were to use it every day I’m sure you’d be fine. So glad this is finally working out, I was about to give up on natural deodorants.

  25. Tina

    This bar is a GAME CHANGER! I’ve tried more then once to switch to a natural deodorant each time faild long term with skin issues, breakouts, odors. I can happily say since adding this to my routine I have been able to use natural deodorants with no more skin issues and no more odor!!!!! Its been nearly a year now.

  26. Steph (verified owner)

    This little bar is essential for all of us trying to quit regular deodorants! The detox process is ruined by other soaps with SLS in them – through trial and error I figured out it was absolutely necessary to only use this kind of soap under my arms while getting my body used to non-aluminum deodorant. It’s gentle enough that even my 5 yr old likes to wash his “pits” with it!

  27. Jackie (verified owner)

    This is one of the best products I have ever had in my shower! It smells divine and it works wonders (I use with the Charcoal Deodorant). My husband is a contractor and even he isn’t smelly when he gets home from work (it’s a miracle!) Highly highly recommend adding this product to your shower regime.

  28. Meghan

    I got this bar along with my detox kit back last summer. YES! I’m wild and detoxed during the summer. Without this bar, I would not have been able to successfully detox. But it worked wonders and kept me smelling fresh all day long.

  29. Monica (verified owner)

    The hype is real! Since my first purchase of this bar I have made it a point to constantly have a backup so I do not run out before re-ordering. This makes a huge difference! I usually only use deodorant now when I go out all day. Otherwise I skip my natural deodorant altogether thanks to the underarm bar! I love it.

  30. Julie

    This bar is pure magic! It lasted a good 3 months and it makes an absolute difference if you want to use natural deodorant. Please never stop making this!

  31. Nisha (verified owner)

    This bar has significantly helped me combat bad body odor! I highly recommend it, especially if paired with one of Kaia’s charcoal deodorants (I love the Cold Pressed Rose). One bar lasts up to a good 4-5 months (and I use mine daily/generously). I’m so glad I came across this company after searching and being unsatisfied with so many other underarm care products! Thank you!

  32. Colleen

    This bar surprised me! Although this didn’t help me get through high stress days, it definitely helped! Will be repurchasing in the near future.

  33. DebK. (verified owner)

    I have been using the underarm bar for over a year now. I love it. No more stinky pits. It really works. I can wear tanks now and not worry about odor.

  34. Colombe B. (verified owner)

    Excellent product. So fresh and clean feeling!!

  35. Rebekah P (verified owner)

    I’m so happy to find this product!! It works so good. Please NEVER stop making this product

  36. Jillian Switzer (verified owner)

    Bought two bars of this soap to help me transition of antiperspirant. Worked wonderfully! They lasted over 6 months and now I can wear natural deodorant with little to no sweat or odor. What a difference!

  37. Debbie K (verified owner)

    I love this soap. I use it every day. It really works. It took longer then three months for ME to detox. But now I go the whole day without odor. I’m glad I found Kaia.

  38. Kelly Fernandes (verified owner)

    Not only keeps my pits stink free but cleared up a rash I had been battling for months in 2 DAYS! I’m a forever user!

  39. Elizabeth Kramar

    This is seriously the easiest way to get rid of any stinkiness from your armpits or feet. It’s so good I even wrote a blog post about it. So many people love love love this product too. Plus you only use a little at a time and not every day so it lasts forever!!

  40. Katie

    Not only is this bar good to keep your natural deodorant working, but it’s good to get rid of skin tags on your body. Took mine and my family tags away in 4 applications.

  41. AJ (verified owner)

    This soap actually gets rid of that rubbery deodorant feeling off of my underarms – they’ll be so squeaky clean!! Plus it smells so fresh!! Definitely a holy grail item!

  42. Virginia L.

    Bought this after seeing it in Real Simple. I was a little skeptical at first but my deodorant stops working after 6 hours and I didn’t want to switch. I’m quite pleased that this soap actually does help. I can wear the deodorant for the whole day without reapplying.

  43. Coralee Whewell (verified owner)

    I think using the soap helped the deodorant work more effectively. Only disappointment was it “melted” away too quickly.

  44. Michelle

    OBSESSED with this soap! Smells amazing and makes me feel so fresh & clean after!

  45. Zelda H

    Works wonders

  46. Chloe

    This bar honestly made my natural deodorant last all day! I’m shocked in the best way!

  47. Nikki Millman

    Incredible soap! Always makes me feel so clean and fresh
