Hair Extension Aftercare and Maintenance

Good hair extension aftercare isn’t complicated, but a few habits make a big difference.

Most problems we see don’t start with one dramatic mistake. It’s usually smaller things repeated over time: brushing too roughly at the roots, going to bed with damp hair, leaving maintenance too long or putting products where they shouldn’t go.

The fitting matters, obviously. But what happens once you leave the salon matters just as much.

This guide covers the practical side of looking after your extensions at home and knowing when it’s time to come back in.

What Actually Makes Hair Extensions Last Well?

Hair extensions need care in two different places: the extension hair itself and the point where it is attached to your own hair.

That distinction is important.

The lengths need moisture, gentle handling and sensible heat styling. The fitting area needs to stay clean, dry and free from unnecessary pulling or product build-up.

If you remember nothing else, start with these:

brush gently and regularly
support the fitting when detangling
don’t sleep with wet extensions
keep heavy oils and conditioners away from attachment points
dry the roots and fittings properly after washing
avoid pulling unnecessarily when tying the hair up
follow the maintenance schedule for your particular method
ask us if something suddenly feels different

The last one is worth paying attention to.

If an attachment starts slipping, pulling or feeling uncomfortable, it’s better to have it checked than to keep adjusting it yourself.

Brushing Extensions Without Tugging at the Roots

Brushing extensions is less about doing it constantly and more about how you do it.

Start lower down the hair and work through any tangles before moving upwards. If you begin at the root and drag the brush through a knot, all that tension has to go somewhere.

Hold or support the hair near the fitting while you work through the lengths.

Once the ends are clear, move gradually upwards.

A simple way to brush extensions

Separate the hair into manageable sections.
Start at the ends.
Work upwards a little at a time.
Support the hair around the attachment area.
Check gently around the roots so sections aren’t tangling together.

Pay particular attention to the back of the head and around the nape. Those areas tend to rub against clothing and are easy to miss when brushing.

You don’t need to attack the hair to get it smooth.

How Should You Wash Hair Extensions?

Wash them thoroughly, but don’t turn the root area into a knot while you’re doing it.

Keep the hair hanging down rather than piling it on top of your head and scrubbing everything together.

Work shampoo through the scalp carefully with your fingers. Rinse properly. When conditioning, concentrate mainly on the mid-lengths and ends unless you’ve been given different advice for your particular fitting.

Keep heavy conditioner away from bonds, beads, tapes and other attachment points. Where you put the product matters.

After washing

Avoid twisting the hair tightly in a towel.

Gently remove excess water and get the root area dry rather than leaving it damp for hours.

The extension lengths can take longer to dry than you expect, particularly when there’s a lot of hair fitted.

Can You Go to Bed With Wet Hair Extensions?

It’s best not to.

Going to sleep while the hair and fitting are still damp can encourage tangling and matting, particularly around the root area where movement against the pillow happens throughout the night.

Dry the hair properly before bed.

Once it’s dry, gathering the lengths loosely can help stop them moving around quite so much while you sleep.

A loose braid or ponytail is often easier to manage than leaving long extensions completely free overnight. The important word there is loose.

There’s no benefit in putting extra tension on the fitting while you sleep.

Heat Styling: The Attachment Matters

Human hair extensions can offer plenty of styling freedom, but where you place your heat matters.

Straighteners, curling tools and other hot appliances should be kept away from extension attachment points unless your stylist has specifically told you otherwise for your fitting.

The lengths are a different matter.

Use heat sensibly, apply an appropriate heat protectant and remember that extension hair doesn’t receive natural oils from the scalp in the same way your own growing hair does.

Too much high heat will catch up with the hair eventually.

You don’t need to stop styling your hair. Just don’t treat maximum heat as the default setting every morning.

Which Products Should I Use on Hair Extensions?

There isn’t one product list that works for every extension fitting.

What matters most is where products are being used.

Conditioning and moisturising products are generally focused through the lengths and ends, where the extension hair needs them most. Oils, masks and heavier products should not automatically be worked up into the fitting area.

The right routine also changes with the texture of the hair.

Straight extensions, loose waves and curly or highly textured hair won’t necessarily need the same amount of moisture or the same styling products.

If you’re unsure about something you already use, bring it up at your appointment. It’s easier for us to look at the actual product than for you to guess.

Curly and Textured Extensions Need a Slightly Different Routine

Curly hair doesn’t behave like straight hair with a bend in it.

Detangling, moisture and how you refresh the curl all need to take the texture into account.

With curly or textured extensions, work in sections and avoid repeatedly brushing through dry curls simply to make them look tidy. That can disturb the pattern and create unnecessary volume or frizz.

Pay attention to the ends and to areas where the hair rubs against clothing.

If your own hair is being blended with the extensions, you’re really looking after two textures at once.

Our Lush Curls page explains more about choosing and matching curly extension hair.

Everyday Habits That Make a Difference

You don’t need a complicated routine. You do need consistency.

Everyday habit	Why it matters
Brushing from the ends upwards	Reduces unnecessary pulling through knots
Supporting the root while detangling	Keeps tension away from the attachment
Drying the fitting properly	Avoids leaving the root area damp for long periods
Keeping heavy products away from attachments	Helps prevent unnecessary build-up around the fitting
Tying hair loosely for sleep	Reduces overnight tangling and friction
Keeping heat away from attachment points	Protects the fitting from avoidable heat exposure
Attending maintenance appointments	Allows grown-out fittings to be adjusted or refitted professionally

These are small things, but they add up.

What Should You Avoid With Hair Extensions?

A few habits cause more trouble than they’re worth.

Try to avoid:

brushing aggressively through knots
repeatedly pulling at individual extensions
picking at bonds, beads or tapes
cutting or removing attachments yourself
putting heavy oils directly onto fitting points
tying the hair extremely tightly
sleeping with the fitting still wet
leaving tangles around the roots to build up
ignoring an attachment that suddenly feels uncomfortable
putting off maintenance because the extensions still look fine from the outside

That last one catches people out.

Your hair continues to grow underneath an extension fitting. What looked and felt neat close to the scalp on day one won’t stay in exactly the same position indefinitely.

Salon Maintenance and Home Aftercare Aren’t the Same Thing

Home aftercare keeps the hair manageable between appointments.

Maintenance is the salon side of it: checking the fitting, adjusting it and refitting where needed.

Depending on the method, that may involve moving attachments back into position, checking individual sections, removing and reinstalling hair, or carrying out a full refit.

Different extension methods need maintenance at different stages, so there isn’t one timetable that applies to everyone.

That’s why the date given for your particular fitting matters more than a generic rule you’ve seen online.

Keep track of your own maintenance date

When you leave the salon, make a note of when you’ve been advised to return.

Don’t wait until the extensions become difficult to manage before thinking about maintenance.

How Do I Know If My Extensions Need to Be Checked?

Sometimes the hair still looks good but the fitting needs attention.

Get in touch if you notice:

unusual pulling or persistent discomfort
an attachment that has slipped or moved significantly
sections tangling repeatedly near the root
matting that you can’t gently separate
several attachments coming loose
a change in how the fitting sits
anything you’re tempted to cut, pull or remove yourself

A photograph can be helpful if you’re unsure what you’re looking at.

We’d much rather you ask than try to solve an attachment issue with a pair of scissors at home.

Swimming, Holidays and Hair Extensions

Extensions don’t mean putting normal life on hold, but holidays can change your usual routine.

Swimming, heat, frequent washing and wearing the hair tied up for longer periods can all mean you need to pay a little more attention to detangling and drying.

After swimming, don’t leave the hair sitting damp and tangled for the rest of the day.

Rinse it, handle it gently and make sure the fitting dries properly.

If you’re going away soon after getting a new set of extensions, mention it at your appointment. Knowing what the hair is about to be put through helps us give you more relevant advice.

Hair Extension Aftercare FAQs

How often should I brush my hair extensions?

Brush them regularly enough to stop tangles building up, particularly through the lengths and around areas prone to friction. Good technique matters more than brushing constantly.

Can I wash my hair normally with extensions?

Yes, but wash in a way that avoids tangling and unnecessary pulling at the attachments. Keep the hair hanging down and dry the fitting thoroughly afterwards.

Can I sleep with wet hair extensions?

We recommend drying the hair and root area before going to bed. Sleeping on damp extensions can make tangling around the roots much harder to manage.

Can I use oil on hair extensions?

Oil may be useful through some extension lengths and ends, but avoid applying heavy oils directly to attachment points unless you’ve been advised otherwise for your particular method.

How often do extensions need maintenance?

There isn’t one schedule for every fitting. Wefts, micro-links, tapes and other extension methods can have different maintenance and refit requirements, so follow the timeframe given for your application.

What should I do if an extension feels loose?

Don’t pull, cut or try to refit it yourself. Contact the salon so the attachment can be checked properly.

Can I use straighteners or curling irons on extensions?

Human hair extension lengths can be styled with heat, but use an appropriate heat protectant and keep hot tools away from attachment points unless you’ve been given different instructions.

Good Aftercare Should Be Manageable

You shouldn’t have to spend half your morning maintaining your extensions.

Brush them properly. Keep the fitting clean and dry. Be sensible with products and heat. Come back when maintenance is due.

And if something doesn’t feel right, ask.

We’d rather look at your actual fitting than have you trying to work it out from general advice online. Wefts, micro-links, tapes, bonds and sew-ins all have slightly different maintenance needs.
