If you've ever caught a whiff of yourself halfway through the day and wondered whether your armpit hair might be part of the problem, you're not alone.
Some guys shave their underarms, others keep things trimmed, and plenty have never given their armpit hair a second thought. But if body odor is something you deal with regularly, you might be wondering whether a little grooming down there could make a difference.
Turns out, it might.
Trimming your armpit hair can make it easier to keep your underarms clean and may help reduce lingering odor. But before you grab the clippers, it's worth understanding what's actually causing that smell in the first place.
Your Armpit Hair Isn't What Smells
Here's something you might not know. Sweat itself is generally odorless.
That unmistakable armpit smell happens when certain bacteria living on your skin break down substances in your sweat.
Your body has two main types of sweat glands. Eccrine glands produce the watery sweat that helps cool you down during a workout or on a hot afternoon. Apocrine glands, found in areas like your armpits, release a thicker fluid containing proteins and fats.
When bacteria break down components of that fluid, they produce the compounds responsible for body odor.
That's why you can finish a workout drenched in sweat and barely smell, yet notice some serious underarm odor on a day when you haven't been particularly active.
Your natural skin bacteria, sweat composition, clothing, and hygiene habits all play a part.
And while armpit hair doesn't create body odor on its own, it can make it easier for that smell to stick around.
So, Does Armpit Hair Make You Smell Worse?
Not necessarily, but it can give sweat and odor more places to linger.
Think about what happens during a long summer day. You're sweating, your shirt is pressed against your underarms, and there's probably a combination of moisture, natural skin oils, and deodorant collecting in the area.
Now add a thick patch of armpit hair.
Hair provides additional surface area where sweat and odor-producing substances can collect. When your underarms stay damp for extended periods, you may notice that unpleasant smell hanging around longer than you'd like.
Of course, this doesn't mean every guy with hairy armpits smells bad.
Some men have plenty of underarm hair and rarely deal with noticeable odor. Others shave regularly and still struggle to stay fresh throughout the day.
Your individual body chemistry matters, and so does your daily grooming routine.
But if you have thick underarm hair and find that odor tends to linger even after washing, trimming might be worth a try.
What Happens When You Trim Your Armpit Hair?
You don't have to shave everything off to make underarm grooming a little easier.
Trimming removes some of the hair where sweat and residue can collect, leaving less for you to wash through when you shower. It can also make it easier to apply deodorant directly to your skin rather than coating a thick layer of hair.
And there's some research suggesting that removing underarm hair can help with odor.
A small clinical study published in the Journal of Cosmetic Dermatology in 2016 looked at how different underarm hair removal methods affected odor after washing. Researchers found that shaving and waxing were associated with greater odor reduction than washing alone under the study conditions.
The study didn't establish whether simply trimming your hair shorter produces the same results, so don't expect a quick pass with the clippers to eliminate body odor.
Still, trimming is a reasonable option if you want to make your underarms easier to clean without committing to a completely shaved look.
Should You Trim or Shave?
That depends on how much hair you want to keep and how your skin responds to grooming.
Trimming is probably the easiest place to start if you've never done much with your armpit hair.
Grab an electric body groomer with a guard and start with a longer setting. You can always go shorter, but you can't exactly put the hair back once you've cut it.
Leaving a little length also means you're less likely to deal with some of the irritation that comes with shaving close to the skin.
Shaving, on the other hand, removes hair right at the skin's surface. That can make washing easier and leave less hair for sweat and odor to cling to.
But smooth underarms aren't for everyone.
Shaving can cause razor bumps, ingrown hairs, and irritation, especially if you have sensitive skin or tend to shave too aggressively.
If you prefer shaving, use a clean, sharp razor and take your time. Avoid repeatedly going over the same area, and give your skin a little breathing room afterward.
And if you'd rather leave your armpit hair alone? That's fine, too. Hair removal isn't a requirement for good hygiene.
Does Trimming Help Your Deodorant Work Better?
If you've ever sprayed deodorant onto thick armpit hair, you know that some of it can end up on the hair instead of your skin.
Keeping your underarm hair shorter may make application a little easier, especially if you use a spray deodorant.
With less hair in the way, you can apply the product more directly and evenly across your underarms.
But that doesn't mean you need to shave for your deodorant to do its job.
What matters most is starting with clean, dry skin and applying the product according to its directions.
It's also worth knowing the difference between deodorant and antiperspirant.
Deodorants are designed to manage body odor. Antiperspirants temporarily reduce the amount of sweat reaching your skin.
If sweat isn't your biggest concern and you simply want to smell fresher throughout the day, deodorant may be all you need.
A Few Grooming Habits That Actually Make a Difference
Trimming might help, but it's only one piece of the puzzle.
If you want to keep underarm odor under control, start with the basics.
Wash your underarms thoroughly. A quick rinse isn't always enough, especially after a sweaty workout. Use a gentle body wash and take a little extra time to clean your underarms, particularly if you have thick hair.
Dry off before applying deodorant. Spraying deodorant onto damp skin isn't ideal. After showering, dry your underarms thoroughly before applying your usual product.
Don't live in your sweaty gym clothes. We get it. Sometimes you finish a workout and have a dozen other things to do before you can shower. But sitting around in damp clothing can make lingering odor worse. Change into a clean shirt when you can.
Pay attention to your shirts. Certain fabrics, particularly some synthetic workout materials, can hold onto unpleasant odors even after washing. If your favorite gym shirt starts smelling the second you put it on, your armpits might not be the problem.
Try trimming if odor keeps hanging around. You don't have to make a dramatic change. Shorten your underarm hair, keep up with your usual hygiene routine, and see whether you notice a difference over the next couple of weeks.
And remember, deodorant works better as part of a consistent grooming routine than as a last-minute attempt to cover up yesterday's sweat.
