On the JJ Barnes Blog, while I know how important it is to keep your hair clean and healthy, I’ve never put much thought into my brush… so today I’m asking, how dirty is your hairbrush, and what is the best way to clean it?
Picture this: your trusty hairbrush, the one you grab every morning to tame your mane, is secretly hosting a microscopic rave. And the guest list? A motley crew of bacteria that could make your scalp crawl—literally. Recent research from Fresha, a beauty and wellness marketplace, revealed that your everyday detangling brush might be a cozy home for some seriously unsavory characters, including bacteria linked to food poisoning, skin infections, and even fecal contamination. Yikes! But don’t toss your brush just yet. With a little know-how, you can keep it clean and your scalp happy. Let’s dive into the dirty details and some pro tips for keeping your hairbrush squeaky clean.

How Dirty Is Your Hairbrush?
A professional swab test on a typical detangling hairbrush uncovered a bacterial lineup that sounds like it belongs in a horror flick. We’re talking about:
- E. coli: Yep, the stuff associated with food poisoning and, uh, fecal matter. While not all strains are harmful, some can cause serious tummy troubles or infections.
- Staphylococcus aureus: This sneaky bug can spark everything from minor skin irritations to full-blown infections like pneumonia.
- Clostridium perfringens: A food poisoning culprit that brings on cramps, diarrhea, and vomiting. Not exactly the vibe you want near your head.
- Bacillus cereus: Another food poisoning fiend, known for causing nausea and diarrhea.
- Pseudomonas aeruginosa: A particularly nasty guest for anyone with a weakened immune system, potentially causing infections in your lungs or urinary tract.
- Faecal streptococci: Not always dangerous, but their presence screams “fecal contamination.” Gross, right?
These findings aren’t just icky—they’re a wake-up call. Your hairbrush is a magnet for scalp oils, dead skin cells, styling products, and apparently, some pretty sketchy bacteria. Left unchecked, these could lead to scalp irritation or worse. So, how do you evict these unwanted guests? Let’s talk cleaning.
How Often Should You Clean Your Hairbrush?

Not all brushes are created equal, and some need more TLC than others. Here’s the breakdown:
- Blow-dry brushes: These get cozy with damp hair and styling products, so clean them after every use to avoid buildup.
- Slick back and edge brushes: These brushes are constantly rubbing up against scalp oils, products, and the hair around your face. Give them a scrub at least twice a week to keep irritation at bay.
- Combs: Unless you’re slathering them with gel, once a week is usually enough.
Regular cleaning isn’t just about hygiene—it’s about keeping your brush in tip-top shape and your scalp free from irritation. Plus, who wants to run a bacteria buffet through their hair?
How to Clean Your Hairbrush Like a Pro

Cleaning your hairbrush doesn’t require a hazmat suit or a chemistry degree—just a few simple steps and some household items. Here’s how to do it without wrecking your brush:
- Clear the Debris: Start by removing loose hair and gunk. A pin-tail comb or a specialized brush-cleaning tool (you can find these online) works wonders for scraping out the fuzz.
- Soak It: Mix warm water with a gentle shampoo (baby shampoo is a great choice) in a sink or bathtub. Let your brush soak for a few minutes to loosen the grime.
- Scrub-a-Dub: Grab an old toothbrush and gently scrub the bristles or teeth to dislodge any stubborn buildup. Be thorough but gentle—you don’t want to damage those bristles.
- Rinse and Dry: Rinse the brush thoroughly under running water, then let it air dry on a towel with the bristles facing down to avoid water pooling in the base.
- Handle with Care: Once a week, wipe the brush handle with an alcohol wipe to zap any bacteria where your hands hang out most.
A quick heads-up: steer clear of harsh chemicals or boiling water. They might seem like a good idea, but they can melt or warp your brush, cutting its lifespan short.
Why It Matters
Your hairbrush isn’t just a tool—it’s a breeding ground for bacteria if you let it get out of hand. Regular cleaning keeps your scalp healthy, your hair looking its best, and those creepy crawlies at bay. Plus, a clean brush glides through your hair like a dream, making styling easier and more effective.
So, next time you reach for your hairbrush, give it a quick once-over. Is it looking a little fuzzy? Maybe it’s time for a spa day. Your scalp (and your stomach) will thank you.
