TREAT THEM WELL, AND THEY’LL NEVER LET YOU DOWN
There's something genuinely special about a fresh set of extensions. The length, the volume, the way your hair moves – it's ✨everything✨.
But like any good investment, extensions only stay that way with the right care behind them. The difference between a set that lasts six months and one that starts looking tired after six weeks almost always comes down to routine.
The good news is that caring for your extensions isn't complicated – it just requires a little consistency and the right products in your corner.
No matter if you’re a newbie or a seasoned wearer wanting to get more life out of your set, here’s how to care for hair extensions like a pro.
STOCK UP ON HAIR EXTENSION CARE PRODUCTS
Just because your extensions aren't growing out of your scalp doesn't mean they don't deserve a little TLC.
If anything, they deserve more.
Your natural hair has a secret weapon: your scalp's sebum, which travels down each strand over time, naturally conditioning and protecting the hair fibre. Extensions don't have that luxury. Without that built-in nourishment, they rely entirely on what you give them, which means the right products aren't optional.
Here are some faves at Hair Island:
OLAPLEX NO.4 BOND MAINTENANCE SHAMPOO
The gold standard of gentle cleansing. Olaplex No.4 is sulfate-free, bond-strengthening and kind enough for regular use without stripping the hair fibre. It cleans effectively while keeping extensions feeling soft, manageable and healthy wash after wash. Follow with the No.5 conditioner for the full
MOROCCANOIL MOISTURE REPAIR SHAMPOO & CONDITIONER
Argan oil-enriched and deeply nourishing, this duo is particularly brilliant for extensions that are feeling dry or lacklustre. It restores softness and shine without leaving any heavy residue, making it a great everyday option for those who wash more frequently.
K18 LEAVE-IN MOLECULAR REPAIR HAIR MASK
KÉRASTASE RÉSISTANCE BAIN EXTENTIONISTE
A salon-grade shampoo that was practically made for extension wearers. Formulated to strengthen and protect the lengths and ends – exactly where extensions need the most attention – it's a step up for anyone looking to seriously invest in their hair care routine.
MOROCCANOIL PERFECT DEFENSE HEAT PROTECTANT
Before any heat tool touches your extensions, this needs to be on them. Lightweight and non-greasy, it protects up to 230°C and doubles as a smoothing primer that leaves hair looking polished before you've even picked up the straighteners.
BUMBLE AND BUMBLE HAIRDRESSER'S INVISIBLE OIL
A finishing product that pulls everything together. A few drops worked through dry extensions adds serious shine, tames frizz and provides a layer of UV and environmental protection. Use sparingly – this is a little-goes-a-long-way situation – but when used right, it's the thing that gives your hair that freshly-styled, glossy finish.
Used consistently, these products will make a noticeable difference to how your extensions look, feel and – most importantly – how long they last. Extensions are an investment, and your product shelf should reflect that.
WASH DAY: DO IT RIGHT
How often you wash your extensions depends on the method you're wearing, but as a general rule, less is more. Over-washing is one of the quickest ways to shorten the life of your extensions, so aim to wash every two to three days at most, and only when necessary.
When you do wash, always brush your extensions through gently before getting them wet to remove any tangles. Wet hair – extension or otherwise – is at its most vulnerable, and tackling knots when the hair is already saturated puts unnecessary stress on both the hair fibre and the bonds.
Wash in a downward motion, working the shampoo through from root to tip rather than piling the hair on top of your head. This keeps the cuticles smooth and minimises tangling. Follow with conditioner from mid-length to ends, avoiding the roots and any bonds or attachment points entirely.
DRYING & HEAT STYLING
Always allow your extensions to dry as thoroughly as possible before sleeping or styling. Going to bed with wet or damp extensions is one of the most common causes of matting and tangling – and once that sets in, it's difficult to reverse.
When using heat tools, a good heat protectant is non-negotiable. Look for a lightweight heat protectant spray or serum that shields the hair fibre without leaving any sticky or heavy residue – applied to damp hair before blow-drying, or to dry hair before straightening or curling.
Keep your tools at a moderate temperature; there's no need to go above 180°C for extensions, and anything higher risks long-term damage to the hair fibre over time.
BRUSHING: THE HABIT THAT MAKES ALL THE DIFFERENCE
Brushing your extensions regularly – and correctly – is one of the simplest things you can do to keep them in great condition.
Use a soft-bristle or loop brush specifically designed for extensions and always start from the ends, working your way up to the roots rather than dragging a brush straight through from top to bottom.
Hold the hair at the mid-length as you brush to reduce tension on the bonds or attachment points and aim to brush through at least morning and evening. Before bed, a loose plait or braid will minimise overnight tangling significantly.
STORAGE (FOR CLIP-INS)
If you're wearing clip-in extensions, how you store them between wears matters just as much as how you care for them when they're in.
Always brush them through before storing and keep them in a breathable bag or box away from direct sunlight and heat. A satin or silk storage bag is ideal – it protects the hair fibre without causing friction.
FAQs
WHAT ARE THE BEST PRODUCTS FOR HAIR EXTENSION CARE?
Sulfate-free shampoos and conditioners are your starting point. Beyond cleansing, a good heat protectant and a nourishing leave-in treatment will go a long way in keeping your extensions looking and feeling their best.
CAN I USE DRY SHAMPOO ON HAIR EXTENSIONS?
Yes, but sparingly. Dry shampoo can be useful for refreshing extensions between washes, but too much buildup around the bonds or roots can cause issues over time. Apply lightly at the roots only and brush through thoroughly afterwards
HOW OFTEN SHOULD I WASH MY HAIR EXTENSIONS?
It depends on the type you're wearing.
For semi-permanent extensions like nano rings, washing every two to three days is a good general guideline – enough to keep your scalp healthy without over-stripping the hair.
For clip-ins, far less frequent washing is needed – roughly every 10 to 15 wears, or when you notice product build-up making them harder to style.
Either way, the key principle is the same: extensions don't produce natural oils the way your scalp does, so less is always more when it comes to washing.
CAN I GO SWIMMING WITH HAIR EXTENSIONS?
It's best to avoid it where possible, particularly in chlorinated or salt water, as both can dry out and damage extension hair significantly. If you do swim, wear your hair up, rinse immediately afterwards and follow with a nourishing conditioning treatment. Always ensure your hair is fully dry before sleeping.
HERE’S THE TRUTH THOUGH
Of course, even the best care routine in the world can only do so much if you're not starting with quality extensions. The foundation is key. Remy human hair that's been properly sourced and crafted will always outlast and outlook cheaper alternatives – no matter how good your product shelf is.
