How to Clean Hair Brushes: 3 Easy Steps

Your hairbrush is a magnet for more than just tangles. Every time you style your hair, that brush collects dead skin cells, scalp oil, old product residue, and dust. If you don’t clean it, you are brushing that grime right back onto your freshly washed head. Learning how to clean your hairbrush prevents greasy roots and keeps your scalp healthy.

How Often Should You Clean Your Hair Brush?

Think of your hairbrush like a sponge. It absorbs everything it touches. Over time, that buildup creates a breeding ground for bacteria and yeast. Using a dirty brush can make clean hair look oily faster and might even irritate your scalp.

• Daily: Remove loose hair strands after every use.
• Weekly: Do a deep clean if you use heavy styling creams, gels, or hairspray.
• Monthly: Perform a deep clean if you generally keep your hair product-free.

Phase 1: Remove the Hair (Pre-Clean)

Before you get the bristles wet, you need to clear out the trap of loose strands. This applies to all brush types.

• Time: 2 minutes
• Difficulty: Beginner

What You’ll Need

• Rat tail comb (or a pen/pencil)
• Small scissors

1. Lift the Hair

Take a pointed object, like the end of a rat tail comb, a pen, or a toothpick. Slide it under the mat of hair at the base of the bristles. Gently pry the hair upward to loosen it from the brush pad.

2. Cut the Knot

If the hair is tightly matted around the bristles, don’t yank it. Take small scissors and cut down the center of the hair clump. This creates two distinct sides that are easier to peel away.

3. Peel and Toss

Pull the loosened hair off the brush with your fingers or a wide-tooth comb. Throw the debris in the trash.

Phase 2: Deep Cleaning (Choose Your Method)

Not all brushes are waterproof. You must choose the right cleaning method based on your brush material to avoid ruining the wood or glue.

Method A: The Soak (For Plastic & Synthetic Brushes)

This method is best for plastic paddle brushes, wet brushes, and solid synthetic combs.

• Time: 30 minutes
• Difficulty: Easy

What You’ll Need:

• Bowl or clean sink
• Warm water
• Shampoo or dish soap
• Old toothbrush

The Steps:

1. Create a Bath: Fill a bowl or sink with warm water. Add a squirt of clarifying shampoo or dish soap to cut through the grease.
2. Soak: Submerge the brush completely. Let it soak for 15 to 30 minutes. This softens the stubborn gray lint and product buildup.
3. Scrub: Take an old toothbrush and scrub between the bristles. Focus on the base of the pad where the “gray fuzz” collects.
4. Rinse and Dry: Rinse with warm running water. Shake out excess moisture. Lay the brush face down on a clean towel to air dry.

Method B: The Dip & Scrub (For Wood & Boar Bristle)

Wood absorbs water, which causes it to swell and crack. Natural boar bristles can also hold unpleasant odors if soaked too long. Use this gentle method instead.

• Time: 10 minutes
• Difficulty: Intermediate

What You’ll Need:

• Warm water
• Gentle shampoo (sulfate-free is best)
• Clean toothbrush

The Steps:

1. Mix Solution: Mix a few drops of shampoo into a small cup of warm water. Do not fill a sink.
2. Dip the Tool, Not the Brush: Dip your toothbrush into the soapy water. Do not submerge the hairbrush.
3. Gently Scrub: Scrub the bristles and the rubber pad with the damp toothbrush. Work in small circles to lift dirt without soaking the wood handle.
4. Quick Rinse: Briefly pass the bristles under running water to rinse the soap. Do not let the water engulf the wooden handle or base.
5. Dry Immediately: Wipe the wood handle dry with a cloth. Lay the brush bristles-down on a towel so water drains away from the wooden base.

Hacks for Stubborn Buildup

Sometimes standard soap isn’t enough. Here are a few tricks to sanitize and refresh your tools.

Vinegar for Sanitizing

White vinegar is a natural disinfectant. It kills bacteria and dissolves mineral buildup from hard water.

1. Mix equal parts water and white vinegar in a bowl.
2. Soak plastic brushes for 10 minutes (skip this for wood).
3. Rinse thoroughly to remove the vinegar smell.

Baking Soda for Deodorizing

If your brush smells like wet dog or stale perfume, baking soda is the answer.

1. Mix 1 teaspoon of baking soda into a cup of water.
2. Dip an old toothbrush into the mixture.
3. Scrub the brush pad and bristles. The grit helps scrub away grime while neutralizing odors.

Dryer Sheets for Static

Lint sticks to brushes because of static electricity. Dryer sheets can help.

1. Place a dryer sheet in a bowl of warm water.
2. Soak your plastic brushes in the water for 15 minutes.
3. Rinse and dry. This helps loosen hair and reduces future static cling.

How to Clean Lice from Brushes

Finding lice is stressful, but cleaning the tools is straightforward. You need to ensure the nits (eggs) are dead so they don’t re-infest the family.

• Time: 24 hours
• Difficulty: Beginner

1. Freeze the Tools

Gather all combs, brushes, and hair accessories. Place them in a sealed gallon-sized freezer bag. Leave the bag in the freezer for at least 24 hours. The extreme cold kills lice and eggs.

2. Boil (Plastic Only)

For sturdy plastic combs, you can boil them in water for 10 minutes. Do not do this with rubber-cushioned brushes or wood, as they will melt or warp.

3. Deep Clean

After freezing or boiling, wash the brushes with warm soapy water to remove any debris.

When to Throw Away a Hairbrush

No hairbrush lasts forever. You should generally replace your brush every 6 to 12 months. However, watch for these signs that it is time to toss it sooner:

• Broken Bristles: If the protective balls on the tips of the bristles fall off, the sharp plastic can scratch your scalp.
• Cracked Pad: If the rubber cushion is cracked, it traps bacteria that you cannot reach to clean.
• Melted Spots: If your hair dryer has melted the bristles, they will snag and break your hair.

FAQs

Can You Soak a Wooden Brush?

No, never soak a wooden brush. Wood is porous and will absorb the water. This causes the wood to warp, crack, and eventually rot. It can also loosen the glue holding the bristles in place.

Why Is There Gray Fuzz In My Hairbrush?

That gray fuzz is a combination of sebum (scalp oil), dead skin cells, dust, and lint from your clothing or bedding. It clumps together with leftover hair product to form sticky, gray lint.

What Do Hairdressers Use to Clean Brushes?

Salons typically use a blue liquid called Barbicide. It is a powerful hospital-grade disinfectant. While effective, it is harsh and not usually necessary for home use unless you are sharing brushes with many people.

How Do I Get Dust Out of My Boar Bristle Brush?

Use a fine-tooth comb to rake through the bristles first. Then, dip a toothbrush in soapy water and gently scrub the bristles from the base outward. wipe it dry immediately with a microfiber cloth.

Can Hydrogen Peroxide Clean a Hairbrush?

Yes, hydrogen peroxide is a good disinfectant. You can mix it with water to soak plastic brushes. It helps kill bacteria and yeast that might contribute to dandruff or scalp acne.

Can a Dirty Hair Brush Cause Greasy Hair?

Yes. If you brush clean hair with a dirty brush, you are redepositing old oil and dirt back onto your strands. This makes your hair look flat and greasy much faster than normal.

How Do You Clean a Round Brush?

Round brushes are tricky because the hair wraps tight. Use small scissors to carefully cut along the length of the barrel (between the bristle rows). Once the hair is cut, peel it off in a sheet. Wash the barrel with warm soapy water and let it air dry.
