How to Clean Hairbrushes (The Right Way): A 5-Minute Deep Clean + Real-World Tips
Your hairbrush doesn’t just collect loose hair. Over time, it traps scalp oil, sweat, dead skin cells, airborne dust, and styling product residue—then redistributes all of it back onto your freshly washed hair every time you brush.
This guide gives you a fast, proven 5-minute sink-bath method, plus brush-type-specific care (boar bristle, wooden, round, electric), and practical tips people actually use at home.
Quick Summary (TL;DR):
Remove hair first (30–60 sec)
Soak bristles-down in warm soapy water (3–5 min) (plastic brushes)
Scrub the bristle base with an old toothbrush (most important step)
Rinse until water runs clear
Dry bristles-down to prevent odor/mold
Quick Navigation
Why You Should Clean Your Hairbrush (It’s Dirtier Than You Think)
Even if your hair looks clean, your brush can hold a “hidden layer” of oil and residue near the bristle base. That buildup can make hair look greasier faster, reduce styling results, and even create a musty smell if moisture gets trapped.
What You’ll Need (Simple Supplies You Already Have)
Basic supplies:
Warm water (not hot)
A few drops of shampoo or gentle dish soap
An old toothbrush (key for the bristle base)
- A towel for drying
Optional (for tough situations):
A small pinch of baking soda (heavy buildup)
A small splash of white vinegar (odor/mineral deposits — rinse well)
5-Minute Deep Clean Method (Best for Most Plastic Brushes)
Step 1 — Remove Hair First (30–60 Seconds)
Before you touch water, remove all trapped hair using your fingers, a comb, or a brush-cleaning rake tool.
For tightly wound hair (especially round brushes), carefully snip it in a few places with small scissors first.
Why it matters: Hair removal speeds up washing and prevents sink clogs.
Step 2 — The 5-Minute Sink-Bath (Soak + Swish + Scrub)
This method works for most plastic paddle brushes and vented brushes:
Fill your sink with warm water
Add a few drops of shampoo or gentle dish soap
Soak the brush bristles-down for 3–5 minutes
Gently swish and rub the bristles in the water
Use an old toothbrush to scrub the bristle base (where residue hides)
Rinse thoroughly until water runs completely clear
Pro reminder: Scrubbing the bristle base is the difference between “looks clean” and “actually clean.”
Step 3 — Rinse & Dry Correctly (Prevents Odor and Mold)
Shake off excess water
Pat dry with a towel
Lay the brush bristles-down on a clean towel
Air-dry completely in a ventilated area
Why bristles-down? Water drains away instead of pooling at the base.

Brush-Type Instructions (Don’t Treat All Brushes the Same)
Paddle & Vented Brushes (Plastic)
✅ Perfect for the sink-bath method above.
Use warm—not hot—water to protect cushioned pads and adhesives.

Round Brushes (Especially Metal Barrels)
⚠️ Minimize soaking time. Water can get trapped inside the barrel.
Modified approach:
Remove hair thoroughly (most important for round brushes)
Quick 2-minute soak instead of 5
Scrub bristles + barrel with a toothbrush
Rinse quickly and dry immediately (prop horizontally)

Boar Bristle Brushes (DO NOT SOAK)
❌ Never submerge. Natural bristles absorb water and can develop persistent odor.
Correct method:
Remove hair first
Mix warm water + a few drops of shampoo in a bowl
Dip only the tips of bristles (avoid the base/wood)
Lightly scrub with a toothbrush
Wipe with a barely damp cloth
Dry bristles-down with airflow

Wooden / Bamboo Brushes (Minimal Water Only)
⚠️ Wood and water are not friends. Avoid soaking.
Safe method:
Remove hair
Wipe handle/body with a slightly damp cloth + mild soap
Use a barely damp toothbrush between bristles if needed
Wipe clean with damp cloth (remove soap)
Dry immediately with a towel

Heated or Electric Styling Brushes (NEVER Submerge)
❌ Electronics + water = disaster.
Safe method:
Unplug and cool completely
Wipe with slightly damp cloth
Use cotton swabs for gaps
For stubborn buildup: cloth dampened with rubbing alcohol
Air-dry fully before plugging back in
Real-World Tips People Actually Use
Shampoo just works: It’s made to break down scalp oils and product residue.
The bristle base is the real problem area: Toothbrush scrubbing is the game-changer.
A quick refresh hack: Some people scrub two brushes against each other under running water with a bit of soap (not as deep, but fast).
Don’ts (Mistakes People Regret)
Don’t use boiling water (warps plastic, loosens glue, flattens cushions)
Don’t soak boar bristle or wooden brushes
Don’t put brushes in the dishwasher on heated dry
Don’t dry brushes bristles-up (water pools at the base → odor/mildew)
How Often Should You Clean Your Hairbrush?
Every 2–3 days: Remove trapped hair (30 seconds)
Once a week: Deep clean (most people’s sweet spot)
Every 3–4 days (heavy product users / oily scalp): Deep clean more often
Every 2 weeks: If you rarely use products and have normal-to-dry scalp
FAQ
Can I clean a hairbrush with shampoo?
Yes—shampoo is one of the best choices for breaking down oils and product residue.
Why does my hairbrush get gray lint/fuzz?
It’s a mix of dust, fabric fibers, dead skin cells, oils, and dried product residue—usually trapped at the bristle base.
How do I remove heavy product buildup?
For plastic brushes: warm water + shampoo/dish soap, soak 3–5 minutes, then scrub the bristle base. Add a pinch of baking soda for stubborn residue.
Can I use vinegar to clean my hairbrush?
You can use a small splash in warm soapy water for mineral deposits—just rinse extremely thoroughly.
My brush still smells after cleaning—what now?
Odor usually means moisture trapped at the base. Dry bristles-down with good airflow. Persistent smell may mean internal mold in the cushion pad.
When should I replace my hairbrush?
Replace if bristles are bent/splayed, pad cracks or feels mushy, odor persists, or the brush snags hair.
