    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!

    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.

    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.

    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!

    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.

  6. 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.

    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.

  8. 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!

  9. 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!

  10. 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.

    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.

  12. Colombe B. (verified owner)

    Excellent product. So fresh and clean feeling!!

  13. Rebekah P (verified owner)

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

    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!

  15. 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.

    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!

  17. 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!!

  18. 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.

  19. 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!

  20. 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.

  21. Coralee Whewell (verified owner)

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

  22. Michelle

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

  23. Zelda H

    Works wonders

  24. Chloe

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

  25. Nikki Millman

    Incredible soap! Always makes me feel so clean and fresh
