Look closely at the base of a well-used hairbrush and you will usually find more than hair: a grey, fluffy layer of dust, dead skin, dried styling product and scalp oil. So how do you clean a hairbrush properly without ruining it? This guide explains how to remove trapped hair, wash off build-up, adapt the method for each type of brush, and dry it so it does not turn musty in Singapore’s humidity.
A dirty brush puts that residue straight back onto freshly washed hair, which is why hair can feel limp or greasy sooner than it should. Brushes also tend to live in bathrooms, where steam from the shower keeps them damp for hours.
The job itself is quick. Removing hair takes a minute or two, and a full wash takes about ten minutes plus drying time. Once it is part of a routine, it barely registers.
Why hairbrush cleaning matters
Each time you brush, the bristles collect shed hair, natural scalp oil, flakes of skin and any leave-in product, serum or spray you use. Over time this forms a sticky mat at the base of the bristles that traps dust from the air. A brush in that state spreads oil and old product through clean hair, does not grip or detangle as well, and can start to smell.
Regular hairbrush cleaning also extends the life of the brush. Build-up and trapped moisture loosen cushion pads, swell wooden handles and make natural bristles go soft and splayed.
Brushes are personal items, and it is sensible for each person in the household, including children, to have their own. If someone in the family has head lice, the US Centers for Disease Control and Prevention’s guidance on treating head lice lists soaking combs and brushes in hot water of at least 130°F, about 54°C, for 5 to 10 minutes as an additional measure. Check that a brush can tolerate heat before you do this; many plastic combs can, but cushioned and wooden brushes may not. Water this hot can scald, so handle it with care and keep children away from the basin.
How often should you clean your hairbrush?
There is no official schedule for this, so treat these as practical guidelines:
- Remove loose hair: every few days, or whenever you can see it building up. It only takes a moment.
- Wash the brush: roughly every two to four weeks for most people.
- Wash more often: if you use a lot of styling products, oils or dry shampoo, if the brush is used on a child’s hair daily, or if anyone has had a scalp problem.
A brush that smells, feels sticky, or leaves your hair looking oily straight after brushing is overdue regardless of the calendar.
What you need
- A wide-tooth comb, the end of a rat-tail comb, or a pencil to lift hair out.
- Small scissors for hair that is tightly wound around the bristles.
- A bowl of lukewarm water.
- Mild shampoo or a few drops of gentle liquid soap.
- A soft old toothbrush, kept only for cleaning.
- A clean towel.
Avoid bleach, strong disinfectants and abrasive powders. They can damage bristles and cushions, and harsh residues are not something you want near your scalp. Never mix cleaning products, and never combine bleach with ammonia or acids. If you choose to wipe a plastic handle with an alcohol-based disinfectant, do it in a ventilated room away from flames and test a small hidden spot first.
How do you clean a hairbrush? A step by step method
Step 1: Remove the hair
- Work the teeth of a comb or the tip of a pencil under the hair at the base of the bristles and lift it upwards in sections.
- Pull the loosened hair away. On a paddle brush it often comes out as one mat.
- If hair is wound tightly, carefully snip across it with small scissors between the rows of bristles, taking care not to cut the bristles or the cushion, then pull out the pieces.
Step 2: Wash off the build-up
- Mix a small squeeze of mild shampoo or soap into a bowl of lukewarm water.
- Dip only the bristle side into the water, or wet the toothbrush in it, depending on the brush type described below.
- Scrub gently around the base of each row of bristles with the toothbrush, where most of the residue sits.
- Wipe the handle and the back of the brush with a damp cloth.
Step 3: Rinse and dry
- Rinse the bristles under lukewarm running water, keeping the brush bristles down so water drains away from the base.
- Shake off excess water and blot with a clean towel.
- Lay the brush bristles down on a dry towel so water can drain out, and leave it in an airy room until completely dry.
Washing methods by brush type
Not every brush tolerates water in the same way, so adapt the wash to what you have.
Plastic brushes and detangling brushes
These are the easiest. Solid plastic brushes with no cushion can be dipped in soapy water and scrubbed freely, then rinsed. They are also the type most likely to cope with a hot water soak if you are dealing with head lice, but check that the plastic will not warp.
Cushioned paddle brushes
Paddle and cushion brushes have a rubber pad with a small air hole in it. If water gets into that hole it can sit inside the cushion for days. Avoid submerging the brush. Instead, dip just the bristle tips or use a damp toothbrush, keep the brush bristles down while rinsing, and dry it face down. If you see water inside the cushion, press gently on the pad over a towel to push it out.
Wooden brushes
Wood swells, cracks and loses its finish when it is soaked. Never leave a wooden brush in water. Clean the bristles with a barely damp toothbrush and a little soapy water, wipe the wood with a damp cloth, then dry it straight away with a towel and leave it to air dry.
Natural bristle brushes
Natural bristles, often found on brushes used for smoothing, are porous and can soften or splay if soaked. Clean them like a wooden brush: lift out the hair, work a small amount of shampoo through the bristles with your fingers or a toothbrush, rinse briefly with the bristles facing down, and dry thoroughly.
Round brushes and combs
Round brushes trap hair in a spiral, so cut along it with scissors before pulling it out. Metal-barrelled round brushes should not be soaked, as water can collect inside the barrel. Plain combs are simple: soak in soapy water for a few minutes, scrub between the teeth with a toothbrush and rinse.
Drying in a humid home, and preventing musty smells
In Singapore, the drying step decides whether a brush stays fresh. A brush left on a bathroom counter after a hot shower may never fully dry, and trapped moisture at the base of the bristles or inside a cushion is what leads to smells and mould.
- Dry brushes bristles down on a towel in a bedroom or living area, ideally with a fan running or the air-conditioning on.
- Wash brushes in the morning or early evening so they have hours to dry before use.
- Do not use a hair dryer on high heat, which can melt or warp bristles and loosen glue.
- Store brushes in an open, ventilated spot rather than a closed drawer, and away from the shower and toilet.

Fitting it into your household routine
Hairbrushes are easy to forget, so give them a regular slot. Many families wash brushes on the same day they change the bed linen, which also makes sense because pillowcases collect the same oil and product; our guides on how often to change bed sheets and washing pillows cover those jobs. While the soapy water is out, it is a good moment to wash makeup tools too, following our guide on cleaning makeup brushes.
If a helper takes care of this for the family, show her the method for each brush type once, and label or separate each person’s brush so they are not mixed up. It is a natural fit within a wider household cleaning schedule.
Replace a brush when bristles are bent, melted or missing, the cushion is split or no longer springs back, or a musty smell remains after washing and drying. And if you notice ongoing itching, flaking, sores or patchy hair loss on the scalp, see a doctor rather than relying on cleaning alone.

Frequently Asked Questions
Can I soak my hairbrush overnight?
Only if it is a solid plastic brush or comb with no cushion, wood or natural bristles. Soaking cushioned, wooden and natural bristle brushes lets water into the pad, swells the wood and softens the bristles, so those should be cleaned with a damp toothbrush and dipped only briefly. In most cases a short soak of a few minutes is all that is needed anyway.
How do I get the grey fluff out of the bottom of my brush?
That grey layer is usually a mix of dust, lint, dead skin and dried product trapped under the hair. Remove the hair first with a comb, then scrub around the base of each row of bristles with a soft toothbrush dipped in warm, soapy water. Rinse with the brush facing down and dry it completely in an airy room.
What is the best way to dry a hairbrush?
Blot it with a towel, then lay it bristles down on a dry towel so water drains away from the base and out of any cushion. Leave it in a well-ventilated room, ideally with a fan or air-conditioning running, until it is fully dry. Avoid drying it in a steamy bathroom or with a hair dryer on high heat.
Should family members share hairbrushes?
It is better for each person to have their own brush. Brushes carry scalp oil, skin flakes and product, and sharing makes it easier to pass on problems such as head lice. If a brush has been used on someone with head lice, the CDC lists soaking combs and brushes in hot water of at least 130°F, about 54°C, for 5 to 10 minutes, provided the brush can tolerate the heat.
When should I replace a hairbrush?
Replace it when the bristles are bent, melted or missing, the cushion is torn or flattened, the handle is cracked, or the brush still smells musty after a thorough wash and dry. A brush in poor condition snags and breaks hair, and a damaged cushion can trap water and grime that cleaning cannot reach.
Conclusion
Keeping a hairbrush clean comes down to three habits: lift out the hair every few days, wash away build-up every few weeks with mild shampoo and a soft toothbrush, and dry the brush face down somewhere airy. Match the method to the brush, keeping water away from cushions, wood and natural bristles, and your brushes will stay fresh and work better for longer.
