FIND YOUR PERFECT SHADE WITH THESE STEPS
Hair extensions have come a long way. What was once a beauty secret reserved for red carpets and music videos is now part of everyday life – and the technology, quality and variety available today means there's genuinely never been a better time to wear them.
We've gone from obvious, one-size-fits-all clip-ins to incredibly sophisticated, natural-looking sets crafted from real Remy human hair in dozens of shades, tones and textures. The game has changed completely.
And with that evolution has come something even more exciting: the ability to colour-match with real precision. The closer your extensions sit to your natural shade – depth, tone and everything in between – the more undetectable they become. And that’s the goal here.
No matter if you're adding length or volume or both, this guide will walk you through exactly how to find your perfect match.
HOW TO COLOUR-MATCH HAIR EXTENSIONS
With a little know-how, nailing your match is far more straightforward than you might think.
STEP 1: KNOW YOUR BASE COLOUR
Before you can match anything, you need to understand what you're working with. Take a proper look at your hair in natural daylight, not overhead lighting, not your bathroom mirror at 7am. Natural light is the only light that shows your true colour accurately.
Consider your depth (how light or dark your hair is overall) and your tone (whether it pulls warm, cool or neutral).
- Warm hair tends to have golden, red or copper undertones
- Cool hair sits more ashy or beige
- Neutral hair sits somewhere in between
This distinction matters more than most people realise when it comes to choosing extensions that truly blend.
STEP 2: MATCH TO YOUR MID-LENGTHS AND ENDS
This is the step that trips most people up. Your instinct might be to match extensions to your roots, but your roots are almost always your darkest point – especially if you've had any lightening, balayage or natural fading over time. Extensions sit from mid-length downwards, so that's exactly where your colour match should come from.
Hold your potential shade against the mid-lengths and ends of your hair in natural light. If it disappears into your hair without a hard line, you're onto a winner.
STEP 3: DON'T IGNORE YOUR UNDERTONES
This is where a lot of people go slightly wrong, even when the depth looks right. Two shades can appear identical at first glance but behave very differently once they're in your hair – because of undertone.
If your hair has warm undertones, a cool-toned extension (even in the same depth) will look off. And vice versa. Always check the tone description when shopping, and if you're ever unsure, err on the side of matching warmth with warmth and cool with cool.
A slightly imperfect depth match is far less noticeable than a clashing undertone.
STEP 4: CONSIDER YOUR COLOUR TECHNIQUE
If your hair is one solid, natural shade, finding your match is relatively straightforward. But most of us are working with something a little more nuanced – highlights, balayage, ombre or grown-out colour that's created natural variation throughout.
For highlighted or balayage hair, a blended or multi-tonal extension shade will almost always look more natural than a single flat colour. Look for shades described as blended, rooted or two-tone, as these are designed to mimic the dimension of colour-treated hair rather than sitting as a block of colour against it.
STEP 5: WHEN IN DOUBT, GO LIGHTER
If you're torn between two shades, the general rule is to go slightly lighter rather than darker. Darker extensions against lighter hair create a more obvious contrast, whereas a slightly lighter shade tends to blend more forgivingly – particularly towards the ends, where hair naturally lightens anyway.
That said, this is a general guide rather than a hard rule. If you have very dark hair, going lighter can look just as jarring. Trust your eye, use natural light and don't rush the decision.
FAQs
CAN YOU COLOUR HAIR EXTENSIONS TO MATCH YOUR HAIR?
Technically, yes – but it's not something we'd actively encourage.
Remy human hair extensions can be coloured, but they're more porous than virgin hair, which makes the result harder to predict – especially when lifting to a lighter shade. There's a real risk of uneven colour, dryness or shortened lifespan, which is why our honest recommendation is to find your match before you buy rather than after.
If you do decide to go ahead, please make sure it's done by a professional who has experience working with extension hair. Going darker is always the safer direction, and the result will be far more predictable than going lighter.
WHAT IF MY HAIR HAS MULTIPLE TONES FROM BALAYAGE OR HIGHLIGHTS?
Opt for a multi-tonal or blended extension shade rather than a single flat colour. These are specifically designed to replicate the natural variation of highlighted or balayage hair, making for a far more seamless blend.
SHOULD I MATCH EXTENSIONS TO MY ROOTS OR MY ENDS?
Always match to your mid-lengths and ends. Your roots are typically your darkest point, and since extensions sit from mid-length down, that's the area that needs to blend most convincingly.
WHAT IF I CAN'T FIND AN EXACT MATCH?
Very few people find a perfect one-to-one match straight away – and that's okay. A close match in the right tone will always look more natural than a closer depth match in the wrong tone. When in doubt, book a consultation with a stylist who can assess your hair in person.
