You cleanse your scalp. You trim your ends. You invest in salon-quality shampoo and serums. But when was the last time you thought about your hairbrush?
At Square One Salon, we know the tools you use at home make all the difference in how your hair looks and feels every day. And while most of us don’t think twice about our hairbrushes, they play a critical role in the health of your strands and scalp. If your brush is more than a few months old—or hasn’t had a good cleaning in a while—it may be doing more harm than good.
Here’s everything you need to know about when (and why) it might be time to toss your old hairbrush and invest in a new hairbrush.
Why Your Hairbrush Matters
Hairbrushes aren't just for detangling and styling—they help distribute oils from your scalp, remove loose strands, and stimulate blood flow for a healthier scalp. The right brush can reduce breakage, improve shine, and even make your blowout last longer.
But over time, even the best brushes wear out. Bristles bend. Cushions break down. And worse? Your brush can become a breeding ground for bacteria, product buildup, and dead skin cells.
A dirty or damaged brush can:
Pull or snag your hair, causing breakage
Scratch or irritate your scalp
Redistribute old oils and product residue
Transfer bacteria, potentially contributing to scalp issues
If that sounds like something you’d rather avoid (we thought so!), read on to learn the signs that your brush has outlived its usefulness.
Signs It’s Time for a New Hairbrush
1. The Bristles Are Bent or Broken
Bristles are the most important part of any hairbrush. Once they start to bend, break, or fall out, your brush can no longer do its job effectively. Damaged bristles won’t glide smoothly through your hair and may actually cause more tangles and damage than they prevent.
2. The Cushion Is Ripping or Sinking
Many brushes, especially paddle or vented designs, use a cushioned base to reduce friction and give a gentler brushing experience. If the cushion is cracked, detached, or worn down, it’s time to replace the brush.
3. Your Brush is Caked with Buildup
Even if you clean your brush regularly, it’s difficult to fully remove years’ worth of product, oil, and dust. If your brush looks cloudy or gunky no matter how often you clean it, it’s probably past its prime.
4. It Smells a Little... Off
Let’s be real: your brush shouldn’t have a smell. If it does, it’s likely harboring bacteria or mildew, especially if it’s stored in a humid environment like your bathroom. Time for a fresh one.
5. You Can’t Remember When You Bought It
Like mascara or makeup sponges, brushes should be replaced regularly. If your brush is older than a year (and used daily), it’s likely worn down—even if it still looks okay on the surface.
How Often Should You Replace Your Hairbrush?
A good rule of thumb: replace your hairbrush every 6 to 12 months, depending on how often you use it and how well you care for it.
Daily use + heat styling? Every 6 months
Occasional use or short hair? Every 9–12 months
Natural bristle brushes? Sooner if the bristles soften or fall out
Pro tip: Use this opportunity to choose a brush that’s perfectly matched to your hair type and needs. Our stylists at Square One Salon can recommend the ideal tools to support your style, from detangling wet hair to creating the perfect blowout.
Choosing the Right Hairbrush for You
All brushes are not created equal. The right one for you depends on your hair texture, length, and goals.
Here are a few favorites we love at Square One:
Boar Bristle Brush: Great for smoothing and adding shine to fine or straight hair. Distributes oils beautifully and reduces frizz.
Paddle Brush: Best for long or thick hair. Covers a lot of ground quickly and is gentle on strands.
Round Brush (Ceramic or Boar): Ideal for blowouts and creating volume. Choose smaller barrels for tighter curls and larger ones for smooth volume.
Vent Brush: Perfect for quick drying and volume. Vents allow air to pass through, speeding up blow-drying time.
Detangling Brush or Wide-Tooth Comb: A must-have for curly, coily, or wet hair. Reduces pulling and helps maintain your curl pattern.

How to Keep Your Hairbrush Cleaner, Longer
Want to extend the life of your new brush? Follow these simple maintenance tips:
Remove hair after every use. A tail comb or your fingers work great for this.
Wash weekly. Soak in warm water with a little gentle shampoo, scrub with a toothbrush, and rinse well. Let it air dry bristle-side down.
Keep it dry. Store your brush in a dry, well-ventilated area—not the steamy corner of your shower.
Avoid sharing. Just like your toothbrush, keep your hairbrush personal to prevent bacterial transfer.
