Natural Deodorant and Underarm Odor: A Holistic Guide to Staying Fresh

By Kiran Kaur, Founder & Skincare Formulator, Body Care by Kiran

You shower, put on fresh clothes, apply deodorant—and still wonder, “What’s that stink?”

Sometimes, the answer is closer than you think. Trust me.

“Mama… It’s You!”

During peri-menopause, when my hormones felt all over the place, I was sitting on the couch with my son when I noticed a smell.

“Son, let me do an underarm detox on you—because you stink!”

He politely replied, “Mama, I hate to say this to you… but it’s you who’s stinky.”

Nothing like your child lovingly solving a mystery you weren’t prepared to solve. 😂

It became a precious memory—and a reminder that even someone who formulates deodorant has underarm moments. Hormonal shift can change sweating and body odor, so our routines may need to change, too.

I’ve also noticed occasional odor changes around Thanksgiving, when I get enthusiastic about processed snacks and holiday treats. That’s my experience, not proof that a particular food caused it. It simply reminds me to pay attention without giving myself a guilt trip.

Why Do My Armpits Smell Even After Showering?

Underarm odor develops when skin bacteria break down substances in sweat. Showering helps, but it doesn’t stop you from sweating again. Hormones, processed foods, medications, stress, personal hygiene, and clothing can influence what you notice.

Smelling different doesn’t automatically mean you’re unclean or need a cleanse. (see Harvard Health link below)

That’s why BCBK’s Underarm Salve includes magnesium hydroxide for odor care, alongside kaolin clay and arrowroot to absorb excess moisture, plus shea butter, jojoba oil, and beeswax to condition skin.

Because sweat is normal, but nobody’s inviting the underarm odor party. 😉

Natural Deodorant vs. Antiperspirant

Deodorant helps control odor. Antiperspirant reduces sweating. When switching to natural deodorant, you may notice more wetness because you’re no longer using the same sweat-reducing ingredients.

Sweat’s main job is cooling your body. Your liver and kidneys handle most waste removal, so stronger odor isn’t evidence that toxins are leaving.

We can respect our body’s need to sweat and still prefer that our underarms don’t announce us before we enter a room.

Do You Need an Underarm Detox?

There’s no proven need for an underarm detox or established “4–6 week” detox timeline when changing deodorants.

The ritual I mentioned to my son was a paste of bentonite clay and apple cider vinegar with the mother—something I’ve personally enjoyed.

And that vinegar smell? My husband cannot stand it. One whiff and he’s finding somewhere else to be. So when I need uninterrupted “me time”… apparently, I have a secret weapon. 😂

No promises about drawing out toxins, but clearing some space around me? My husband can confirm.

Jokes aside, clay and vinegar can irritate skin, especially after shaving. “With the mother” doesn’t make vinegar irritation-free. Gentle cleansing with ACV + Bentonite clay + Water is a simpler starting point, and burning or itching isn’t a detox milestone. Read more about armpit detox here.

Simple Habits for Fresher Underarms

Cleanse gently and dry well. Avoid aggressive scrubbing.

Follow product directions. More deodorant isn’t always more effective. Use our Underarm Salve as a overnight Mask (Kaolin Clay and Magnesium based). Consistency is key.

Wear fresh, cotton, silk, wool clothing. Your deodorant shouldn’t have to battle yesterday’s shirt.

Notice personal patterns. Stress, hormonal changes, certain foods, and alcohol may influence sweating or odor.

Listen to your body | skin. Stop using products that cause irritation. 

Seek your holistic | medical advice for sudden odor changes, unexplained heavy sweating, night sweats, or persistent skin irritation.

BCBK’s Underarm Salve + Mineral Salt Mist

Our duo pairs a baking soda-free Underarm Salve with a potassium alum Mineral Salt Mist for everyday odor care.

Choose from Sandalwood, Blue Tansy and Rose, or Lavender, featuring aromatic ingredients instead of synthetic fragrance.

What About Potassium Alum?

Potassium alum is potassium aluminum sulfate, a mineral salt that can occur naturally. A 2016 laboratory study found that it inhibited four bacterial strains associated with underarm odor. This supports its potential use in deodorants, although it doesn’t establish how long BCBK’s finished mist provides protection.

Our mist and salve are made without aluminum chlorohydrate, a common antiperspirant ingredient. It uses a different aluminum-containing salt instead.
