THE HORMONAL IMPACT ON DEODORANT EFFICACY

Has your go-to deodorant ever… lost the plot? 

One day it works like a dream, then suddenly it’s barely making it to the interval. There are plenty of possible causes, but the answer can often be related to hormones. 

So if you’ve noticed a shift in your body odour, or found your deodorant has stopped working right when you needed it most, read on to find out what may be going on behind the scenes. 

PSA: We’re using terms like “female hormones” to reflect commonly searched-for language, but as a fiercely inclusive brand we recognise that hormonal fluctuations are not limited to one gender. All are welcome at AKT, and our products are built around shared experiences - such as abruptly smelling like a neglected PE kit bag for no apparent reason. Thanks a bunch, hormones. 

Right, let’s get into it. 

What Actually Causes Body Odour?

Let’s clear something up: sweat isn’t actually the villain. 

Body odour is caused by bacteria breaking down sweat in warm, enclosed areas (like our underarms). It’s why even the most pristine routine can still result in smelly or sweaty armpits.

Usually, a good wash and a reliable deodorant will keep things firmly under control. But if things do start to change, that can be your cue to take a look backstage. 

Can Hormones Cause Smelly Armpits?

In short: yes. Very much so.

If you’ve ever wondered “can hormonal imbalance cause smelly armpits?”, your hunch was right. Hormonal shifts can increase sweat production and alter how your body smells, which is why smelly armpits and hormones often go hand in hand.

This can show up during:

• Smelly armpits during pregnancy and early pregnancy

• Postpartum smelly armpits 

• Smelly armpits when breastfeeding (as if you don’t have enough to juggle)

• Perimenopause sweaty armpits

• Menopause smelly armpits (more on that in a mo)

• Smelly armpits when going through GAHT or HRT 

So if your deodorant suddenly isn’t cutting it, your hormones may have been sneakily rewriting the script.

Menopause and Smelly Armpits

Awareness is thankfully starting to grow around the symptoms people experience when going through the menopause. Mood shifts, brain fog, sleep problems, itchy ears – and very commonly, a change in BO. 

So why do so many people notice smellier armpits during menopause? Surprisingly, it’s not necessarily to do with hot flashes. 

A drop in oestrogen during menopause can lead to increased testosterone levels, which in turn ramps up sweat production. More sweat = more bacteria = a noticeable shift in odour.

So if you’re experiencing:

• menopause underarm sweating

• menopause smelly armpits

• or simply wondering “can menopause cause smelly armpits?”

You’re not alone. It’s incredibly common and manageable with the right support (and the right menopause deodorant).

Stopping the Stink: A Deodorant That Keeps on Performing

When hormones change, your deodorant needs to work harder to keep up.

That means choosing a formula that works with your body, not against it. Many people turn to a natural deodorant for smelly armpits, especially as awareness grows around ingredients like parabens.

AKT’s The Deodorant Balm is designed to absorb moisture without blocking sweat glands, helping to manage excessive sweating underarms – while keeping odour firmly under control.

So whether you’re looking for:

• the best deodorant for menopause

• the best women’s deodorant for smelly armpits

• or simply a reliable deodorant for sweaty armpits no matter your gender

…The Deodorant Balm is built to go the distance.

Performance Notes

How our hormones behave is largely out of our control, but there are a few daily habits that can help when dealing with smelly armpits hormone situations:

• Start with clean skin
  Our Body Wash Concentrate and Foaming Body Scrub will provide a good cleanse for your skin to help get rid of the bacteria that causes odour.

• Apply beyond the underarms
  Inner thighs, under the bust, behind the knees – anywhere prone to sweat can benefit, just make sure it’s whole-body safe like The Deodorant Balm. 

• Keep things trimmed
  At AKT we’re firm supporters of hair everywhere! Still, underarm hair can hold onto bacteria and odour, so if you’re struggling with smell, trim your underarm hair when needed.

So… What’s the Best Deodorant for Smelly Armpits?

AKT’s The Deodorant Balm is the UK’s most-awarded deodorant for a reason. Our formula naturally absorbs perspiration without blocking your sweat glands, helping you feel fresh and dry all day long.

It’s trusted by performers, athletes and those navigating everything from pregnancy smelly armpits to smelly armpits during perimenopause and menopause because it’s designed to perform under pressure.

But you needn’t take our word for it. Here’s just a few of the tens of thousands of glowing reviews:

Amazing menopause product

"I have been using this product for the last 5 months and will NEVER use anything else again!! Entering my menopause journey has left me a bit stinky and this has completely stopped any pong!!!"

– Victoria

Smells devine!

"The deodorant balm works wonders! Going through menopause has changed my body's reaction to perspiring and I needed a new deodorant that was safe to use and would work. I will never go back! The AKT balm feels good and such a tiny amount is needed plus it's gentle enough to use under breasts, down my back and upper lip."

– Jacqui P. 

The only deodorant that works for me.

"As a postpartum mum, I found that I was sweating like I never had before. I used to *gasp* use a popular spray full of aluminium. However…. It started to cause me severe irritation on my newly sensitive skin. I tried 4 different natural brands before coming across AKT. Each brand either left me still stinky, still sweaty and sticky or they just smelled BAD. I’ve been a loyal AKT user for the past year and will never go back to anything else. It’s a beautiful added ritual to my mornings and evenings!"

– Franchesca C
