Underarm Bar

The underarm bar is the first and only product I have found that keeps me and my (naturally super sweaty) husband feeling fresh and smelling clean for a full 24 hours no matter what our daily activities consist of. That says a lot in triple degree heat in Texas! We will continue to use this product until the end of time

Best stink eliminator!

I purchased the underarm charcoal soap for my husband. He was tired of struggling with deodorants and them not working effectively! After the first application, he noticed the difference right away and is one super happy customer!! Since starting the soap he’s added the deodorant to double up on the benefits. I’ve also purchased my sporty kids a couple of bars too and they are really happy with how effective it these products work. Thank you Kaia Naturals!

Underarm Bar for the Win!

I have been using the Takesumi detox method for over a month now and I will never go back to my old deodorant. The underarm bar curbs my odor and gives me the extra confidence that I am smelling fresh. I had cysts on my pits from other products and using the underarm bar and detox deodorant has improved the look and feel of my pits.


Amazing customer service!

Underarm Bar + Discovery Deodorant Set

I’ve been using the Underarm Bar for a few years now and am so glad I found it! When switching to clean deodorant, I went through some smelly times. The underarm bar helped tremendously with that. When my favorite clean/green deodorant was discontinued, I decided to try Kaia deodorants with the discovery set. Turns out I like how they perform better than the other deodorant I was using! Just need to figure out which scent I like best because they’re all lovely! If you need a clean deodorant that performs, you can stop your search here. And, do yourself a favor and get the Underarm Bar, too!
