How to Wash Hair Brushes at Home (5 Best Tips)

Be honest when was the last time you washed your hairbrush? Last week? Last year? Never?
If your brush could talk, it would beg for a spa day. And no, yanking out hair once in a while doesn’t count as cleaning. Built-up oil, dead skin, product gunk… it’s basically skincare enemies reuniting on your brush.

And listen, you can own the best shampoo on the planet, but if you’re brushing with a dirty tool, you’re undoing all that effort. Tragic. The good news? Learning how to wash hair brushes is way easier than you think and honestly kind of satisfying.

So grab a claw clip, throw your hair into a messy bun, and let me walk you through 5 best ways to clean your hair brushes bestie style. Stylish, simple, zero overwhelm. Let’s glow up your tools

Why Washing Your Hair Brush Actually Matters (Yes, Really)

Quick reality check: every time you brush, you transfer oil, sweat, dust, and styling product right back onto clean hair. Gross? A little. Fixable? Totally.

Clean brushes mean:

• Fresher hair for longer
• Less scalp irritation
• Better styling results
• Way fewer “why does my hair feel greasy already?” moments

IMO, this is peak low-effort beauty maintenance. Five minutes. Big payoff.

1. The Classic Shampoo Soak (AKA The No-Brainer Method)

This one’s the little black dress of brush cleaning—simple, reliable, always works. Start by pulling out all the trapped hair (use a comb or your fingers). Then fill a bowl with warm water + a few drops of shampoo. Submerge the brush bristles-down and let it soak for 10–15 minutes. Swirl it around gently, scrub between bristles with an old toothbrush, rinse, and air dry bristles facing down.

Why people love it:
It’s easy, uses stuff you already have, and works on most plastic brushes.

Best for:

• Everyday paddle brushes
• Detanglers
• Synthetic bristles

Hot tip: Skip soaking wooden brushes they hate water like suede hates rain.

2. Baking Soda Detox (For Brushes That Have Seen Things)

If your brush smells… weird? Or looks cloudy? This is your girl. Mix 1 tablespoon baking soda + warm water in a bowl. Add a drop of shampoo for extra grease-cutting power. Let the brush soak for 15–20 minutes, then scrub and rinse. Baking soda breaks down stubborn buildup like a champ. It’s giving deep clean energy.

Why this works:
Baking soda lifts oil and residue without harsh chemicals.

Best for:

• Product junkies (dry shampoo lovers, I see you)
• Brushes with visible white buildup

IMO this is the move when your brush needs a full reset, not a casual rinse.

3. Vinegar Rinse (Don’t Panic It’s a Glow-Up)

Yes, vinegar. No, your brush won’t smell like a salad. After shampooing your brush, mix 1 part white vinegar + 2 parts water and pour it over the bristles. Let it sit for 5 minutes, then rinse thoroughly. Vinegar kills bacteria and dissolves mineral buildup. Science, but make it chic.

Why people swear by it:
It disinfects without fancy cleaners and leaves bristles squeaky clean.

Best for:

• Brushes used on oily scalps
• Brushes that need sanitizing

Pro tip: Let it dry completely the vinegar scent disappears once dry. Promise.

4. Toothbrush Detail Clean (For Precision Queens)

Sometimes your brush doesn’t need a bath it needs attention to detail. Dip an old toothbrush into soapy water and scrub between each row of bristles. Focus on the base where grime loves to hide. Rinse lightly and pat dry. This method feels oddly satisfying, like cleaning white sneakers.

Why it’s clutch:
You control the clean and avoid soaking sensitive materials.

Best for:

• Wooden brushes
• Boar bristle brushes
• Brushes with cushions

IMO this is perfect if you’re a “clean but careful” type.

5. Dish Soap Power Wash (When Things Get Serious)

Dish soap cuts grease like nobody’s business. Use one tiny drop in warm water and scrub the brush thoroughly. This is not an everyday method—it’s more of a brush intervention.

Why it slaps:
Dish soap removes heavy oils fast. No mercy.

Best for:

• Brushes caked with hair oils
• Brushes used on extensions or wigs

Just rinse well leftover soap can dry out hair next time you brush.

How Often Should You Wash Hair Brushes?

Real talk? Once a week is ideal. If you use lots of product, maybe twice. Bare minimum? Every two weeks. Set a reminder. Pair it with laundry day. Romanticize it. Whatever works. Because clean hair deserves clean tools. Period.

What NOT to Do (Learn From My Mistakes)

I once soaked a wooden brush overnight. RIP. Avoid these common fails:

• ❌ Soaking wooden or cushioned brushes
• ❌ Using boiling water
• ❌ Drying bristles-up (water seeps into the base)
• ❌ Skipping drying time

Let brushes air dry fully before using them again. Damp brushes = bacteria party.

Quick Brush-Cleaning Cheat Sheet

If you’re in a rush, remember this:

• Plastic brush? Shampoo soak
• Product buildup? Baking soda
• Needs disinfecting? Vinegar rinse
• Wooden brush? Toothbrush scrub
• Grease overload? Dish soap

Save this. Screenshot it. You’ll thank me later.
