Kérastase Chroma Absolu NZ: Colour Protection and Shine

If you've just walked out of the salon with fresh balayage, a glossy brunette or a re-toned blonde, the next few weeks decide how long it lasts. Colour fade isn't only about pigment washing out. It's the hair fibre weakening, the surface roughening and that mirror-like shine going flat. Chroma Absolu is the range our colourists reach for when a client's investment in colour needs to actually hold, and it's become one of the most-asked-for lines we ship across New Zealand.

Here's how it works, who it suits, and how to build a routine that keeps your colour looking like it did the day you left the chair.

What Kérastase Chroma Absolu is built to do

Chroma Absolu is Kérastase's dedicated colour-treated hair range. It targets the two things colour clients care about most: stopping premature fade and keeping that glassy shine. The formulas are built around lactic acid and a centella asiatica (cica) complex, which work on the hair's surface and inner fibre rather than just coating the outside.

The acid technology matters more than it sounds. Colouring and lightening lift the cuticle and shift the hair's pH. When the cuticle stays raised, pigment leaks out faster and light scatters instead of reflecting, which is why faded hair looks dull as well as washed out. The acid-based formulas help the cuticle lie flatter, so colour stays locked in and the surface reflects light properly. That's the shine you're paying for.

The Chroma Absolu range, piece by piece

It's a focused line, which makes it easy to build a routine without overthinking it. These are the heroes we recommend most often through the Chroma Absolu collection.

Bain Riche Chroma Respect is the cleansing cream for thick, dry or coarse colour-treated hair. It cleanses gently while feeding moisture back in, so you're not stripping the colour you just paid for. For finer colour-treated hair, the lighter Bain Chroma Respect does the same job without weighing the roots down. If you're not sure which suits you, the rule of thumb is simple: coarse or parched hair takes the Riche, fine or flat hair takes the lighter Bain.

Fondant Cica Chroma is the everyday conditioner, formulated to detangle and smooth while reinforcing fibres weakened by colour. It's the one that makes wet hair feel manageable again and stops mid-lengths snagging.

Masque Chroma Filler is the weekly deep treatment. Think of it as a top-up for hair that's been pushed by repeated colour or lightening. It targets the weak points along the fibre and rebuilds body and bounce, which is why it sits comfortably alongside other masks and treatments in a serious colour-care routine.

Soin Acide Chroma Gloss is the one clients fall for. It's an in-shower acid gloss you apply after shampooing, leave for a couple of minutes and rinse. The high concentration of acid technology smooths the cuticle in one short hit, and the shine result is genuinely visible the first time you use it. If your colour has gone flat between salon visits, this is the fastest fix.

Sérum Chroma Thermique is the leave-in heat protectant. It shields colour from heat styling up to high temperatures while adding slip and shine, which is non-negotiable if you're using a straightener or hot brush on coloured hair. It works as both a styling primer and a finishing oil, so it earns its place among our leave-in treatments and hair oils.

Who Chroma Absolu suits best

If you colour your hair at all, Chroma Absolu is relevant to you. It's especially worth it if you're spending real money on balayage, foils, vivids or a glossy refresh, because the range is designed to protect that exact investment.

That said, it's not the only answer. If your hair is more damaged than it is faded, our colourists often pair Chroma Absolu's colour protection with a bond-repair approach from the Metal Detox family, which neutralises the metal particles in hair and water that cause colour to oxidise and break during the colour process. For hair that's outright fragile and snapping, repair-focused care should come first, then colour protection on top.

Blondes have a slightly different brief. Chroma Absolu protects the integrity and shine of lightened hair, but it isn't a toning range, so it won't neutralise brassiness on its own. If your priority is keeping blonde cool and bright, look at Blond Absolu for the purple-toning side, and use Chroma Absolu underneath it for the protection and gloss. Plenty of our blonde clients run both.

Building your routine

A complete Chroma Absolu routine is more straightforward than it looks. Wash with your matched Bain, follow with Fondant Cica Chroma on mid-lengths and ends, and swap in the Masque Chroma Filler once a week instead of your conditioner. Add the Soin Acide Chroma Gloss whenever colour starts looking dull, and never heat-style without the Sérum Chroma Thermique first.

One habit makes the biggest difference: keep your water cooler when you rinse colour-treated hair, and don't over-wash. Hot water reopens the cuticle and accelerates fade, which undoes the work the acid formulas are doing. Stretching washes to every two or three days protects both your colour and your time.

Where Chroma Absolu fits in the wider Kérastase world

Kérastase is a system, and Chroma Absolu handles one job extremely well: colour. If you've got other concerns running at the same time, the line plays nicely with the rest of the Kérastase range. Coloured hair that's also dehydrated benefits from a Nutritive layer, fine coloured hair that needs body can borrow from Genesis or Densifique, and stressed scalps still need their own care regardless of what's happening on the lengths. The point is to treat colour with Chroma Absolu and not expect it to fix everything else.

Frequently asked questions

What does Kérastase Chroma Absolu do?

Chroma Absolu is Kérastase's colour-treated hair range. It uses lactic acid and a cica (centella) complex to help the cuticle lie flat, which locks colour pigment in and reflects light for glossy shine. It protects salon colour from premature fade while smoothing and strengthening the fibre.

Is Kérastase Chroma Absolu good for blonde hair?

Yes, it protects the shine and integrity of lightened blonde hair, but it isn't a toning range, so it won't neutralise brassiness on its own. Many of our blonde clients pair it with Kérastase Blond Absolu for purple toning and use Chroma Absolu underneath for protection and gloss.

Which Chroma Absolu shampoo should I use?

Use Bain Riche Chroma Respect if your hair is thick, dry or coarse, and the lighter Bain Chroma Respect if your hair is fine or tends to go flat. Both cleanse gently to avoid stripping colour, the difference is how much moisture they deliver.

What is the Chroma Absolu acid gloss treatment?

Soin Acide Chroma Gloss is an in-shower treatment you apply after shampooing, leave for a couple of minutes, then rinse. Its high concentration of acid technology smooths the cuticle for visible shine straight away, making it the fastest fix when colour starts looking dull between salon visits.
