A hairbrush picks up loose strands, styling products, dust and scalp oils as you use it. Cleaning it does not need fancy equipment, but the safest method depends on whether the brush is plastic, wood, padded or made with natural bristles.
Start by removing trapped hair
After each use or every few sessions, pull out loose strands with clean fingers, a wide-tooth comb or a dedicated brush-cleaning tool. Work gently around the bristles instead of cutting into the cushion or yanking out bristle rows. Removing hair first makes later washing more effective because water and cleanser can reach the base of the brush.
Check what your brush is made from
Solid plastic combs and many plastic brushes can tolerate a brief wash, but wooden handles, natural bristles, rubber cushions and glued components may be damaged by soaking. Some electric styling brushes should never be immersed in water. Check the maker's cleaning instructions before using any liquid, especially on heated tools or delicate materials.
For a washable plastic comb
Remove hair, rinse under lukewarm water and use a small amount of mild liquid soap with a soft clean toothbrush to reach between the teeth. Rinse well, shake away excess water and leave the comb to dry completely on a clean towel. Avoid very hot water that could warp plastic, and do not use abrasive scrubbers that roughen the surface.
For a cushioned or mixed-material brush
If the manufacturer permits damp cleaning, use a lightly moistened cloth or soft brush with a little diluted mild cleanser to clean the bristle bed. Avoid letting water collect inside the cushion, under glued sections or in the handle. Wipe away soap residue and allow plenty of airflow for drying. A submerged brush that traps water may develop odor or deterioration over time.
What about wooden brushes and natural bristles?
Wood can swell or crack if left wet for long periods, while certain natural bristles lose their shape with harsh washing. Remove hair frequently and follow the specific care instructions provided for that brush. If wiping with a damp cloth is allowed, use minimal moisture and dry promptly. Do not assume a social-media boiling-water method is safe for every tool.
How often should you clean it?
The right interval depends on how often you style, use sprays or oils and share tools. Removing hair regularly and doing a deeper clean whenever visible residue builds up is a practical approach. For someone using heavy leave-in products daily, more frequent cleaning may help. There is no magic weekly schedule that suits every brush and material.
Is disinfecting the same as cleaning?
No. Cleaning removes loose hair, oils, dust and residue; disinfection is a separate process with product-specific contact times and material compatibility. A casual splash of alcohol does not guarantee a brush is disinfected. If tools are used in a professional salon or shared setting, follow the relevant hygiene standards and manufacturer guidance.
Drying is as important as washing
Set a washed brush in a position that allows trapped moisture to drain where appropriate, and wait until fully dry before storing it in a closed drawer or bag. Never place a wet electric tool near a socket, and do not switch it on to 'speed dry' unless the manufacturer explicitly advises it. Persistent dampness and odor are signs to reconsider the cleaning method.
When is it time to replace a brush?
Bristles that have sharp broken tips, a cracked cushion, shedding bristle clusters, exposed adhesive or an odor that remains after proper care are reasonable signs of wear. A damaged brush can snag hair and be uncomfortable on the scalp. Replacing a worn tool may be more useful than buying another expensive treatment for apparent breakage.
The five-minute routine
Remove the trapped hair, inspect the brush material, clean only with an approved method, rinse or wipe away residue and let it dry completely. Repeat before buildup becomes stubborn. Good tool hygiene is not about making every brush sterile; it is about keeping hair care comfortable and avoiding unnecessary residue or pulling.
