How to Disinfect a Hairbrush Safely: Clean First, Then Disinfect When Needed
How to Disinfect a Hairbrush Safely: Clean First, Then Disinfect When Needed
A hairbrush can collect shed hair, skin flakes, oils, dust, and styling-product residue, but that does not mean it needs a strong disinfectant every time you clean it. The most useful distinction is between cleaning and disinfecting. Cleaning physically removes debris and many germs with soap, water, and scrubbing. Disinfecting uses a chemical product to kill germs that remain after cleaning.
According to the CDC's cleaning and disinfecting guidance, updated June 3, 2025, cleaning with soap and water is enough in most household situations; extra disinfection is mainly useful when someone is sick or at higher risk of illness. That principle applies well to a personal hairbrush: remove the buildup first, then add a disinfecting step only when there is a reason and the brush material can tolerate it.
Do You Actually Need to Disinfect Your Hairbrush?
For routine personal use, usually not. A brush covered with hair spray residue, scalp oil, or lint needs a thorough cleaning before anything else. The CDC notes that dirt and organic material can interfere with disinfectants, so spraying a dirty brush and calling it sanitized skips the most important first step.
Disinfection becomes more reasonable after a household illness, when a brush has been shared in a situation where germ transfer is a concern, or when a healthcare professional has told you to take extra precautions. Head lice are a separate case with their own CDC procedure, covered below.
Action: If the brush is for one healthy person and there is no known exposure, clean it thoroughly and dry it completely. If there is a specific infection or contamination concern, clean first and then use a compatible disinfection method.
Can Your Hairbrush Safely Get Wet?
Before washing or disinfecting anything, look at how the brush is built. A one-piece plastic detangling brush can usually tolerate much more water than a wooden brush, a natural-bristle brush, a pneumatic cushion brush, or a powered styling brush.
Brush type
Practical starting point
Main caution
Solid plastic or metal brush
Warm soapy water, rinse, then optional compatible surface disinfectant
Check the disinfectant label for the surface type and contact time
Cushioned or vented brush
Clean the bristles and exposed base with limited water
Avoid flooding holes, seams, or the cushion unless the maker permits immersion
Wooden handle or natural bristles
Use minimal moisture and the manufacturer's care method
Soaking can damage finishes, wood, natural fibers, or adhesives
Electric or heated brush
Unplug it and follow the manufacturer's cleaning directions
Do not immerse powered components
Manufacturer instructions really do vary. Tangle Teezer's current FAQ tells users to remove loose hair, scrub with soap and warm water, rinse, and let the brush dry naturally. By contrast, Mason Pearson's care guidance for its pocket brushes calls for warm water and mild shampoo and says to dry with the bristles facing down. There is no one drying orientation or soaking rule that fits every brush.
Action: If your brush has wood, a rubber cushion, natural bristles, glued parts, or electronics, check the maker's instructions before immersing it or applying a disinfectant.
What Do You Need?
A comb tail, hair pick, or your fingers for lifting trapped hair
Mild liquid soap or shampoo
A clean soft toothbrush or small cleaning brush
Warm water
A clean towel and a well-ventilated place to air-dry
Optional: an EPA-registered disinfectant labeled for the relevant hard, nonporous surface, if disinfection is actually needed
How Do You Disinfect a Washable Plastic or Metal Hairbrush?
1. Remove all trapped hair first
Pull out loose strands from the bristles or teeth. For a dense paddle brush, lift hair from the base with a comb tail or hair pick before pulling it away. Removing this layer makes the next cleaning step much more effective.
Start by removing trapped hair so soap and water can reach the bristles and brush base.
Action: Keep working until you can see the base of the brush between the bristles. If hair is tightly wound around a round brush, loosen it carefully without cutting or scratching the bristles or barrel.
2. Wash away oil and styling-product residue
For a fully washable plastic or metal brush, use warm water and a small amount of mild soap or shampoo. Scrub between the bristles, around the base, and along the handle with a soft toothbrush. Rinse away soap and loosened residue. For a cushioned, wooden, natural-bristle, or partly glued brush, clean only the parts the manufacturer says may be wetted rather than automatically soaking the whole tool.
A soft toothbrush helps remove oily buildup and styling residue between bristles before any disinfecting step.
This cleaning step is not optional if you plan to disinfect. The CDC's household guidance says surfaces should be cleaned before sanitizing or disinfecting because soil can make it harder for chemicals to reach and kill germs.
Action: Do not move on until visible residue is gone. If the brush still feels waxy or sticky, wash it again rather than compensating with more disinfectant.
3. Disinfect only if there is a reason—and follow the label
