How to Clean and Maintain Hair Tools: Hairdryers, Clippers, Straighteners & More
There is something I wish everyone would do when they buy a new hairdryer, clipper, straightener or hot brush: read the instructions.
I know. Not exactly the glamorous part of opening a beautiful new hair tool.
Most of us remove the appliance, admire it, plug it in and leave the instruction booklet sitting in the box with all the other bits we promise ourselves we'll look at later.
But here's the thing.
That little booklet tells you how to clean your particular tool, how often it needs maintenance, what not to do and, importantly, how to troubleshoot some very simple problems.
And when you've invested in a good electrical tool, two minutes of maintenance can be far more useful than two years of complaining that it "doesn't work like it used to".
Let's look after these things properly.
Why cleaning your hair tools matters
Hair tools have a fairly tough life.
Hairdryers inhale dust, hair and styling product residue.
Clipper and trimmer blades collect tiny cut hairs while two pieces of metal move against each other at speed.
Straighteners and curling irons accumulate heat protectants, oils, serums and sprays.
Then, quite often, everything gets put straight back into a drawer.
Over time, that can affect airflow, cutting performance, heat distribution and the general condition of your equipment.
You don't need to become a hair-tool mechanic.
You simply need a few good habits.
Hairdryer not working properly? Check the filter first
This is my number one.
If your hairdryer suddenly feels less powerful, becomes unusually hot, cuts out or doesn't seem to have the airflow it once did, don't immediately assume the motor has given up.
Turn it around.
Look at the filter.
A hairdryer needs to pull air freely through its rear intake. With that air comes dust, lint, hair and particles of styling products.
Eventually, the filter can become clogged.
Restricted airflow means the dryer cannot breathe properly and may have to work much harder.
Think of trying to run while breathing through a scarf.
Not ideal.
How to clean a hairdryer filter
Every model is different, so your manufacturer's instructions always come first.
As a general routine:
- Switch the hairdryer off and unplug it.
- Allow it to cool completely.
- Remove the rear filter or filter cover if the manufacturer says it is removable.
- Gently remove accumulated hair, dust and lint.
- If the filter is specifically described as washable, clean it according to the manufacturer's instructions.
- Let every washable component dry completely before putting it back.
And I mean completely.
Water and electrical appliances don't need an introduction.
Does your hairdryer have an automatic cleaning function?
Some newer professional hairdryers include an automatic or reverse cleaning cycle.
Fantastic.
But having the feature isn't enough. You actually need to use it.
Check the manual for your specific model, as the activation method and recommended cleaning frequency can vary.
This is exactly why I keep coming back to that instruction booklet.
Clippers and trimmers need two things: cleaning and oil
This applies whether you're cutting human hair, trimming a beard or grooming a pet.
Those little blades are doing an enormous amount of work.
As they move, cut hair collects around and between the blade surfaces. Without proper cleaning and lubrication, friction increases and performance can deteriorate.
This is why many clippers and trimmers arrive with two rather unexciting-looking accessories:
A little brush.
A little bottle of oil.
Please don't throw them away.
They're there for a reason.
A simple clipper and trimmer routine
Again, follow the instructions supplied with your particular model, but routine maintenance generally involves:
- Switch the appliance off.
- Remove attachment combs.
- Use the supplied brush to remove loose hair from the blades and surrounding areas.
- Apply the manufacturer's recommended blade oil in the specified locations.
- Run the tool briefly if instructed to distribute the oil.
- Wipe away excess oil.
- Store the clipper clean and dry.
For a professional who uses clippers repeatedly throughout the day, maintenance will naturally need to occur more frequently than for someone tidying their hair at home every few weeks.
And yes, use proper clipper oil
Please don't get inventive here.
The oil supplied with your clipper or a suitable professional blade oil is formulated for the job.
Your kitchen cupboard does not contain an exciting alternative.
If you use clippers regularly, replacement blade oil is one of the few inexpensive purchases I'd absolutely recommend.
Not because it's glamorous.
Because a small bottle of oil is considerably cheaper than replacing a professional clipper prematurely.
Cleaning and disinfecting are not the same thing
This distinction is particularly important for professionals.
Removing visible hair from a clipper blade is cleaning.
Disinfecting equipment between clients is a separate hygiene process.
Lubricating the blade is another step again.
Hairdressers, barbers and professional groomers should follow the relevant hygiene requirements for their workplace as well as the manufacturer's instructions for their equipment.
Don't assume that spraying any household cleaner onto a professional tool is suitable.
Use products designed and approved for the purpose.
Straighteners collect more product than you think
Take a close look at the plates of a straightener you've been using for months.
Heat protectant, hairspray, serum and styling products can gradually leave residue on the surface.
That build-up isn't something I want sliding through freshly washed hair.
The solution is simple.
Switch the straightener off.
Unplug it.
Allow it to cool completely.
Then clean the plates using the manufacturer's recommended method, typically with a soft cloth.
Avoid abrasive scourers or anything that could scratch or damage the plate coating.
These are precision surfaces, not last night's roasting tray.
What about curling irons and wands?
Same principle.
Styling products can gradually accumulate on the barrel, particularly if you're a fan of hairspray or texture products.
Once the appliance is switched off, unplugged and completely cool, clean the barrel according to the manufacturer's instructions.
Don't scrape stubborn residue off with a sharp object.
If your beautiful curling iron requires a butter knife to clean it, we've taken a wrong turn somewhere.
Hot brushes and heated styling brushes
Hot brushes need a little extra attention because they collect both product residue and actual hair.
Once the tool is unplugged and cool, regularly remove strands trapped around the bristles.
Clean accessible styling surfaces according to the manufacturer's directions, and prevent water from entering electrical components.
A brush full of old hair isn't giving anyone their best blowout.
Don't forget the cord
Here's another habit I'd love to retire.
Finishing your hair, then winding the cord very tightly around the appliance.
It looks beautifully neat.
The cord may disagree.
Repeated bending and pulling of the cable, particularly near where it enters the appliance, can cause unnecessary stress.
Instead, allow the tool to cool and loosely coil the cord for storage.
If you notice exposed wiring, cracking, fraying, unusual heat around the connection or intermittent power, stop using the appliance.
Electrical repairs are not a beauty hack.
Cordless tools need care, too
Rechargeable clippers, trimmers and styling tools have made life wonderfully convenient, but batteries and charging systems still need to be treated properly.
Use the charger supplied or approved for your model.
Keep charging contacts clean and dry.
Follow any manufacturer instructions regarding charging and long-term storage.
And don't assume that because another charger physically fits, it's suitable.
That's a gamble I wouldn't take with an expensive tool.
Before deciding your hair tool is faulty, do this
This might be the most useful section of the entire article.
If your tool suddenly isn't behaving as expected, spend two minutes checking the basics before assuming something serious has happened.
Hairdryer
Is the rear filter clogged?
Does your model have a manual or automatic cleaning cycle?
Is the filter fitted correctly?
Clippers and trimmers
Are the blades packed with cut hair?
Have they been cleaned?
Have they been oiled according to the instructions?
Is the battery properly charged?
Is the blade or attachment seated correctly?
Straighteners, curlers and hot brushes
Is there significant product build-up?
Has the appliance been allowed to cool or reset if it has overheated?
Is the power connection secure?
If you've followed the manufacturer's troubleshooting instructions and the problem persists, absolutely contact the retailer, manufacturer, or authorised service agent, as appropriate.
That's what we're here for.
But sometimes the difference between "my dryer has stopped working" and "my dryer is working perfectly again" is a filter that needs cleaning.
Two minutes.
Drama over.
A five-minute maintenance routine
If you own several electrical hair tools, I'd make this a habit every few weeks.
Hairdryer: Check the filter.
Clipper or trimmer: Remove hair and check whether the blades need oil.
Straightener: Check the plates for product residue.
Curling iron: Check the barrel.
Hot brush: Remove trapped hair.
Cordless tools: Check the charging contacts and charger.
Everything: Look at the cords and plugs for visible damage.
Professionals who use equipment every day should check and maintain tools much more frequently, according to the manufacturer's recommendations.
Can proper maintenance make hair tools last longer?
Good maintenance can certainly help preserve performance and avoid preventable problems.
It cannot make an electrical appliance immortal.
Motors wear.
Batteries age.
Blades eventually need replacing.
Components can fail.
But there is a very big difference between normal wear and making an appliance fight through a blocked filter or running dry clipper blades day after day.
You paid for the tool.
Give it a fighting chance.
My professional rule
I've spent decades working with hair tools every day, and my rule is very simple:
Look after the tools that look after your hair.
You don't need an elaborate maintenance cupboard.
You don't need to spend Sunday afternoon polishing your hairdryer.
You need consistency.
Clean the filter.
Brush out the blades.
Use the correct oil.
Remove product build-up.
Store your equipment properly.
And when you buy a new tool, read the instructions before that booklet disappears into the box forever.
Professional tools are designed to work hard.
They shouldn't have to survive neglect as well.
Quick answers
How often should I clean my hairdryer filter?
Follow the instructions for your particular model. Frequency depends on the dryer and how heavily it is used. A professional salon dryer will naturally collect debris faster than one used occasionally at home. Don't wait for performance to noticeably deteriorate before checking it.
Why does my hairdryer keep cutting out?
Restricted airflow from a dirty filter can contribute to overheating and thermal protection activating on some dryers. Switch it off, unplug it and check the manufacturer's troubleshooting and filter-cleaning instructions. If the problem persists after correct maintenance, stop using it and seek appropriate support.
Why are my clippers pulling hair instead of cutting cleanly?
Hair build-up, inadequate lubrication, blade alignment, blade wear or other issues can affect cutting performance. Start with the cleaning and lubrication procedure specified by the manufacturer. If that doesn't resolve it, the blades or tool may need professional attention.
How often should clipper blades be oiled?
There isn't one schedule for every clipper. Follow the manufacturer's instructions for your model. Professional tools used continuously may require frequent lubrication.
Can I clean my straightener while it's warm?
Don't. Switch it off, unplug it and allow it to cool before cleaning according to the manufacturer's instructions.
Can I use any oil on clipper blades?
Use blade oil recommended by the clipper manufacturer or a suitable professional clipper oil. Don't substitute household or cooking oils.
Should I keep the instruction manual?
Yes.
That may be the most valuable maintenance product included in the box.
The takeaway
A good hair tool is an investment.
Looking after it shouldn't be complicated.
Most routine maintenance comes down to a handful of habits that take minutes but can help keep your equipment clean, efficient and performing as intended.
And if there's one thing I'd love you to remember after reading this, it's this:
Don't wait until something stops working before you start maintaining it.
Your hairdryer filter shouldn't need to stage a protest before you clean it.
Your clipper blades shouldn't need to start pulling before they see a drop of oil.
And that instruction booklet?
Give it five minutes.
It might save you considerably more later.
