How to Match Hair Extensions to Your Hair Colour | Dream Girl

There is a moment, when the shade is right, where nobody can tell. Not your colourist, not your closest friend, not you in the mirror at the wrong angle in bad lighting. The hair simply looks like yours, only more of it.

Getting there is less about luck than most people think. Shade matching is a skill, and like most skills it comes down to knowing what to look at. Length you can adjust. Texture you can style. Colour is the one that has to be right from the start.

Here is how to get it right the first time.

Start with your base, not the bottle

The most common mistake is matching to what your hair is supposed to be rather than what it actually is.

If you colour at home or in the salon, the shade on the box or the number in your notes tells you what went on. It does not tell you what came out, or what has happened since. Colour shifts. Warm tones lift as they oxidise, ash tones fade, and six weeks of shampoo does its own quiet work.

So put the box aside. Take a section from the mid-lengths, roughly at the level where your extensions will sit, and work from that. That is your true base, and that is what you are matching.

If you have visible regrowth, note it, but do not match to it. Extensions sit below the root area. Matching to a root you can see is how people end up with hair that reads darker at the ends than it should.

Warm, cool or neutral: reading your undertone

Two people can both be a medium brown and look completely different, because underneath the depth there is a tone. This is the part that catches people out.

Warm hair carries gold, red or copper underneath. In sunlight you will see amber or a hint of ginger through the mid-lengths. Shades like Caramel Brown, Golden Chestnut and Light Toffee live here.

Cool hair reads ashy, with grey, blue or violet underneath. In sunlight it stays smoky rather than glowing. Ash Brown, Dark Ash Brown, Medium Ash Brown and Mouse Brown sit in this family.

Neutral hair sits between the two without pulling strongly either way. Chocolate, Medium Brown and Chestnut Brown are good examples.

A quick way to check: hold your hair against a sheet of plain white paper in daylight. The white gives you a reference point, and whatever tone is hiding in your hair will announce itself.

Depth is easier to correct than tone. A shade one level too light or too dark can often be blended in. A warm shade sitting next to cool hair will always look like a separate piece, no matter how well it is fitted.

How to read our shade names

Our shade names carry more information than they first appear to, and once you can read them the range gets much easier to navigate.

Plain names are solid, single-tone shades. Jet Black, Natural Black, Darkest Brown, Dark Brown, Chocolate, Medium Brown, Chestnut Brown, Mouse Brown, Dark Blonde, Medium Blonde, Light Honey Blonde, Strawberry Blonde, Lightest Blonde, Snow White. One colour, root to tip.

Numbers are the professional colour code, so your stylist can work from them directly. Darkest Brown 2, Dark Brown 3, Dark Ash Brown 9, Medium Ash Brown 10, Caramel Brown 12, Dark Blonde 16, Light Golden Blonde 20, Golden Honey Blonde 26. If you know your colour number from the salon, this is the fastest route to your match.

B is for balayage. Light Brown Balayage (B2/8), Brown Soft Balayage (B4/8/1) and Ash Brown Platinum Balayage (B6A/60) are graduated, going deeper at the top and lighter through the length, the way hand-painted colour does.

P is for a blend. Dark Light Brown Mix (P2/6), Light Brown Ash Blend (P6/14), Cool Ash Brunette Blend (P6A/2A), Black Auburn Blend (P1B/30), Brown Strawberry Blonde Mix (P4/27) and Silver Blonde (PSilver/60) weave two tones together through the whole length rather than graduating.

Named melts are our multi-tonal shades, blended for a specific finish. Sugar Syrup (18/613), Canyon Clay (18/16/613), Glam Touch, Gold Mist and Luminous Blonde.

Where you check the shade matters

Never make the final call under a bathroom spotlight, and never under shop lighting.

Daylight is the only honest light. Stand near a window, ideally on an overcast day, and hold the hair flat against your own rather than in front of it. Overcast light is the least flattering and the most truthful, which is exactly what you want.

Then check again indoors, under the lighting you actually live in. Warm bulbs at home pull a cool shade slightly warmer, and the reverse is also true. If it holds up in both, you have your match.

When your hair is not one colour

Most hair isn't. Balayage, highlights, root shadows, sun-lifted ends, three years of grown-out colour: it is rare for anyone to be a single flat shade from root to tip.

This is where the B and P shades earn their place, because they already have movement built in and behave the way coloured hair behaves.

If you have balayage, match the top third of the extension to your mid-lengths and let the graduation handle the rest. The Luxe Prestige Slim Tape In carries the widest selection of balayage and blended tones in the range, so it is the natural starting point if your colour is multi-tonal.

If you have highlights rather than balayage, a P blend usually reads better than a B graduation, because highlights run through the length rather than concentrating at the ends.

And if your own colour is genuinely uniform, a single tone is the cleaner choice. Blended shades on flat hair read as a deliberate style rather than an invisible one, which is lovely if it is what you want and jarring if it isn't.

Going lighter, going darker

You do not have to match. Plenty of women use extensions to add dimension deliberately, placing lighter pieces around the face or deeper tones underneath for contrast.

If you are going lighter, keep it within two shades of your base and place the lighter hair where light would naturally hit: around the face, through the top layers. Further than that without professional placement tends to read as separate rather than blended.

If you are going darker, you have more room. Deeper shades sit more forgivingly against a lighter base, particularly underneath.

The Luxe Volume Clip In set carries the broadest shade range of anything we make, running from Jet Black through to Snow White, which makes it the easiest place to experiment with dimension.

Silver, platinum and snow white

These deserve their own note, because they behave differently.

Cool, pale shades show every trace of warmth around them. If your own hair has any yellow or gold left in it, Snow White or Silver Blonde will sit next to it and expose it immediately. That is not a fault in the hair, it is simply how pale tones work.

If you are working in this family, get your own colour properly toned first, then match. It is worth doing in that order.

Between two shades? Go darker

It happens constantly. You narrow it down to two, and neither is quite it.

Go darker. Slightly deeper extensions recede into your own hair and read as depth. Slightly lighter extensions come forward and read as a separate piece. Depth is quiet, lightness is loud.

The better option, though, is not to guess at all. Screens are unreliable: every phone, laptop and monitor renders colour differently, and no photograph of hair has ever been entirely honest about tone.

A quick checklist

• Match to your mid-lengths, not your roots and not the box
• Check the undertone against plain white paper in daylight
• Confirm in overcast daylight, then again in your home lighting
• Look at a B or P shade if your own colour has movement in it
• Stay within two shades if you are going lighter
• Tone your own hair first if you are working in platinum, silver or white
• When torn between two, take the darker one

FAQ

Can I dye human hair extensions to match my colour?

Human hair can be coloured, but it behaves differently to hair growing from your head, because it is no longer receiving natural oils. Depositing colour or toning down is generally safer than lifting. We would always recommend a colourist rather than a home kit, and a strand test first. Choosing the right shade at the point of purchase is far easier than correcting it afterwards.

What do the letters and numbers in the shade names mean?

Numbers are the professional colour code your stylist works from. B indicates a balayage shade, graduated from deeper at the top to lighter through the length. P indicates a blend, where two tones run together through the whole length.

How do I match extensions to balayage or highlighted hair?

Match the top section of the extension to your mid-lengths and let a B or P shade handle the rest. Trying to match a single flat colour to multi-tonal hair rarely works, because the eye picks up the lack of movement immediately.

Do screens show hair colour accurately?

Not reliably. Screen calibration, ambient lighting and photography all affect how a shade appears. Use online images to narrow your options, then confirm properly before ordering.

Will the extensions still match after my hair grows out?

Your own colour will keep shifting, so at some point the match will drift. Most people refresh their colour on a schedule anyway, and it is worth having your extensions with you at that appointment so your colourist can work to both.

Where to go next

Once you have your shade, the next question is how you want to wear it. Our guide to professional versus ready to wear extensions walks through both routes and who each one suits.
