To clean out hair brushes, remove shed hair, wash the bristles in soapy water, rinse well, and let each brush air dry fully.
If your brush looks fuzzy with lint and old strands, every pass through your hair spreads oil, styling residue, dust, and dead skin back onto your scalp. Learning how to clean out hair brushes keeps your hair fresher between wash days and helps your brushes last longer.
Why Clean Hair Brushes Regularly
A brush touches your scalp day after day. Oil, styling creams, dry shampoo, and airborne dirt grab onto the bristles and cushion. Over time that mix forms a gray film that clings to each pin and sits at the base of the bristles.
Dermatology and hair care experts explain that this kind of buildup traps bacteria, yeast, and tiny skin flakes. That grime can transfer right back to freshly washed hair, leaving it dull, sticky, or itchy much sooner than it should.
A dirty brush can also snag more. Hairs caught around the base tighten and act like little nets, tugging at strands every time you pull the brush through your hair. That extra pull can stress fragile or processed hair and encourage breakage over time.
How To Clean Out Hair Brushes Step By Step
This method works for most plastic and mixed bristle brushes. You can adjust the soak time and water level later when you deal with wood or natural bristles.

Step 1: Remove Trapped Hair
Start by pulling out as much hair as you can with your fingers. Turn the brush sideways and work from one end to the other. If the hair is knotted tight around the base, slide the tip of a tail comb under the clump and lift it up in sections. Short sessions now save time during each deep clean.
Step 2: Mix A Gentle Cleaning Solution
Fill a bowl or sink with warm water and add a small squeeze of shampoo. Swish your hand to create light suds. Many stylists suggest using the same gentle shampoo you like on your scalp, since the goal is to remove oil and product without stripping or damaging bristles.
If the brush feels coated with heavy styling products or hairspray, add a teaspoon of baking soda to the water. This boosts the cleaning power of the mix and helps cut through sticky residue on the bristles and cushion.
Step 3: Soak And Scrub The Brush
Place the brush bristle-side down in the bowl. For plastic brushes you can usually submerge the head fully. For cushioned or vented designs, keep the water line below the handle connection so water does not seep into glued joints.
Let the brush soak for about 5–10 minutes. Then dip the toothbrush into the soapy water and scrub along the base of the bristles. Work in small sections, moving row by row, to loosen lint and residue that sits at the roots.
Step 4: Rinse Thoroughly
Once the base looks clean, rinse the brush under a gentle stream of warm water. Point the bristles downward so dirty water runs away from the handle. Keep rinsing until the water runs clear and no more suds appear between the bristles.
Any leftover soap on the brush can transfer to your hair later and leave it dull or stiff, so take your time on this step.
Step 5: Dry Your Brush Correctly
Shake off extra water and gently pat the bristles with a towel. Lay the brush bristle-side down on a dry towel in a warm, airy spot. This position lets moisture drain away from the cushion and handle so parts do not loosen or warp.
Let the brush dry completely before you use it again. If the core stays damp, it can harbor mildew or odors that show up every time you style.
Cleaning Hair Brushes For Different Materials
Not every brush can handle a long bath. Material and construction matter, so adjust your routine to keep each tool in good shape.
Plastic And Synthetic Bristle Brushes
Plastic handles and nylon pins are the easiest to scrub. They tolerate full immersion in warm, soapy water, as long as you avoid water that feels scalding to the touch. Cleaners such as diluted vinegar or a small amount of household ammonia in water are also common options when brushes need extra degreasing.
After soaking, use the toothbrush to scrub the pad, barrel, and around each pin. Pay close attention to vent holes or cushioned centers where lint tends to collect. Rinse well and air dry completely before storage.
Boar Bristle And Mixed Bristle Brushes
Boar bristles are more delicate and can dry out if you leave them in water for too long. Skip long soaks and focus on quick dips instead. Swirl just the bristles in the soapy water, keeping the handle as dry as possible.
Scrub from base to tip in the same direction as the bristles. Rinse under a light stream of water, squeeze out extra moisture with a towel, and dry the brush with bristles facing down.
Wooden Handles And Cushioned Pads
Wood swells and cracks when it absorbs too much water. For brushes with wooden backs or handles, clean the bristles with a damp toothbrush and soapy water, but wipe the wood itself with a barely damp cloth.
If the brush has a soft rubber or foam cushion, dunk only the bristles and pad for a short soak, then pat everything dry. Leaving a cushioned brush soaking in a sink for half an hour can let water seep behind the pad and loosen the glue.
Thermal And Metal Barrel Round Brushes
Round brushes with metal or ceramic barrels help speed up blowouts, but those barrels collect fine lint and melted product. Pull out trapped hairs first, then soak the barrel in soapy water while keeping the handle joint above the water line.
Use a toothbrush to scrub through each row of holes around the barrel. Rotate as you go so you clear lint out of every opening. Rinse well and dry the brush on a towel with the handle resting higher than the barrel, so water drains away from the joint.
How Often To Clean Hair Brushes
Stylists generally suggest a quick hair removal session every few days and a deeper wash at least once a month. A Real Simple guide also recommends monthly cleaning, or every two weeks with heavy styling products. That schedule keeps grime from building up between bristles.
People with dandruff, scalp acne, or frequent product use may benefit from more frequent cleaning. Some dermatology clinics advise weekly cleaning for those with breakout-prone skin so bacteria and oil from the brush do not sit against the skin on the neck and hairline.
A simple rule: if the base of the brush looks gray, fuzzy, or dusty even after you pull out loose hair, it is time for a wash.
| Brush Use Habit | Deep Clean Schedule | Quick Hair Removal |
|---|---|---|
| Light daily brushing, little product | Every 4 weeks | Every 3–4 days |
| Daily brushing with styling creams or oils | Every 2 weeks | Every other day |
| Heavy hairspray or dry shampoo use | Weekly | After each styling session |
| Dandruff or scalp acne present | Weekly, plus disinfecting step | Every other day |
| Shared brushes in a household | Every 1–2 weeks | Before each new user |
| Rare use travel or gym brush | Every 6–8 weeks | Before packing away |
| Professional salon tools | Multiple times per week | Between clients |
Extra Hygiene Steps For Hair Tools
Cleaning out hair brushes is mainly about appearance and styling performance, but hygiene matters too. Brushes can collect microorganisms, especially when they live in warm, humid bathrooms.
When And How To Disinfect
After washing and rinsing plastic brushes or combs, you can dip the bristle area in a mix of one part household vinegar to four parts water for a few minutes, then rinse and dry. Some guides also suggest diluted ammonia as an option for synthetic tools.
If a family member has head lice, medical sources such as the Mayo Clinic Health System suggest soaking combs and brushes in hot water at least 130°F (about 54°C) for several minutes, then drying completely, along with washing bedding and hats.
Shared Brushes And Breakouts
Sharing brushes with others spreads oil, flakes, and any microbes clinging to the bristles. That mix can irritate sensitive skin along the hairline and may contribute to clogged pores on the forehead or back.
If you need to share tools, clean and disinfect them between users. In a salon, regulations often require cleaning combs and brushes between clients for this reason.
Common Mistakes When Cleaning Hair Brushes
A few habits wear out brushes faster or leave them less clean than you might expect. Avoid these missteps and your tools will stay in good shape for longer.
Using Water That Is Too Hot
Boiling or near-boiling water can warp plastic bristles and damage glue that holds pads and handles together. Warm water that feels comfortable on your skin is enough to loosen oil and product buildup.
Soaking Wood Handles For Too Long
Leaving a wooden brush or a brush with a wooden handle soaking in a sink can cause swelling, cracks, and peeling finish. Keep soaks short and targeted at the bristles, then dry the wood right away.
Skipping Regular Hair Removal
Waiting months before you pull shed hair from the bristles makes every deep clean harder. Strands wrap around the base, trap lint, and block access to the cushion when you scrub.
Putting Wet Brushes Away In Closed Spaces
Stashing a damp brush in a drawer, gym bag, or cupboard slows drying and can lead to musty smells. In some cases a fine dark film may appear along the pad or handle, which suggests mold growth.
Always dry brushes in an open, airy space before you pack them away. Lay them on a towel or hang them with bristles pointing down so water does not collect at the base.
Cleaning Hair Brushes Thoroughly At Home
Once you know how to clean out hair brushes, the job turns into a quick, almost automatic part of your routine. Pull out shed hair several times a week, give your main brush a soapy soak every few weeks, and match the method to the material of each tool.
A clean brush glides more smoothly, keeps fresh hair cleaner for longer, and cuts down on lint, flakes, and product streaks showing up in every style. With a small bowl, a bit of shampoo, and ten spare minutes, you can reset all your brushes and start your next styling session with a fresh slate.
