Kérastase Première NZ: The Repair Range, Explained

Première is the range we hand over most often when someone sits down, runs their fingers through their lengths and says the words we hear every week: "it just keeps snapping." It's Kérastase's answer to genuinely damaged, weakened hair, and it's become the quiet workhorse in our colour room. When a client's ends are fraying or their hair has lost its bounce after one too many lightening sessions, this is the line we reach for first.

If you've been searching for Kérastase Première in NZ and trying to work out whether it's right for you, here's the honest, salon-floor version of what it does, who it suits and how to actually use it.

What Kérastase Première is built to fix

Première is a repair range, not a hydration range. That distinction matters. Plenty of haircare promises to make hair "feel" better by coating it, but the moment is gone the second you wash again. Première is designed to work on the structural side of damage — the breakage, the split ends, the loss of strength and elasticity that comes from colour, heat and the everyday wear of brushing and tying hair up.

The hero of the range is glycolic acid (you'll see it called Acide Glycolique on the packaging). It's the same family of ingredient skincare brands use to refine and resurface, and Kérastase has built the line around it to help reduce breakage and smooth the hair fibre from the inside out. The result our clients notice most isn't a single "wow" — it's that their hair stops shedding broken pieces on the bathroom floor and starts holding its shape between appointments.

So Première sits squarely in the damaged and broken hair camp. If your concern is more about thirst — hair that drinks moisture and stays dry — you may be better starting with a hydration-led line instead, and we'll come back to that below.

Who it's actually for

We reach for Première when we see a few specific things in the chair:

• Colour-worn hair that's started to break. Blondes and balayage clients especially, where repeated lightening has thinned the strand and the mid-lengths feel papery.
• Visible split ends and frayed ends between cuts, where someone wants to buy a little time before their next trim.
• Hair that's lost its stretch. Healthy hair stretches and springs back; damaged hair stretches and stays limp or snaps. Première targets that elasticity.
• The "rough cuticle" feeling — that catch and tangle when you run your hands down the lengths.

If that sounds like your hair, it's worth a look. If your hair is genuinely healthy and you just want shine or softness, this is more firepower than you need, and there are gentler everyday options in our full Kérastase range that will suit you better.

The Première routine, the way we'd build it

Repair works best as a small system rather than one hero product, because each step does a different job. Here's how we'd put it together for someone with breakage-prone, colour-treated hair.

Start with the shampoo

The Première shampoo is the foundation — it cleanses while beginning the glycolic-acid repair work. If you've got dense or particularly tangly hair, the decalcifying-style cleanser in the range is the one we point people towards, because it helps clear the mineral and product build-up that makes damaged hair feel even rougher. Browse the wider shampoos selection if you want to compare.

Follow with a conditioner or mask

This is where the real repair happens. The Première conditioner detangles and seals, and the more intensive mask is the step we'd push hardest for anyone whose ends are actively splitting. Used once or twice a week in place of your conditioner, a treatment mask gives the fibre proper time to drink in the active ingredients. Have a look through our masks and treatments to see the heavier-duty options.

Lock it in with a leave-in

The step most people skip and shouldn't. A Première leave-in or repair serum carries on protecting through heat styling and daily handling, which is exactly when breakage tends to happen. If you blow-dry or use irons, this is non-negotiable for us. Our leave-in treatments sit alongside the rest of the line.

You don't need every product at once. If budget's tight, start with the mask and the leave-in — those two carry the most weight for damaged hair.

Première vs the rest of the Kérastase wall

Kérastase makes a lot of ranges, and it's easy to buy the wrong one for your hair. Here's how we steer people.

If your hair is colour-treated and lightened but more brittle and dry than actively breaking, our colourists often pair or compare Première with the bond-and-strength side of the line. The Blond Absolu range is purpose-built for lightened blondes — toning and nourishing brassy, fragile colour — and Résistance is the classic strength-and-repair line for weakened, over-processed hair.

If the core issue is moisture rather than damage — hair that's parched, rough and dehydrated — we'd point you to Nutritive for everyday nourishment or the dry and dehydrated edit across brands.

And if you simply want the showpiece shine on hair that's in decent nick, Elixir Ultime is the cult oil range our clients buy on repeat. It's a different job to Première — gloss, not structural repair — so don't reach for it expecting to fix breakage.

The short version: Première is for hair that's breaking. If yours isn't breaking, there's probably a better-matched range.

Why genuine matters with Kérastase

Kérastase is the range our colourists use daily, and we only sell what we'd put on our own clients. We're an authorised stockist, so everything is the real product, properly stored and current — which is worth saying because professional haircare gets faked and grey-imported more than most people realise, and old or counterfeit stock simply won't perform. With a repair line like Première, where the active ingredients are doing the heavy lifting, authenticity is the difference between results and a wasted spend.

One last salon note: repair takes a few weeks. Hair grows slowly and the fibre rebuilds gradually, so give a Première routine a solid month before you judge it. The clients who stick with it are the ones who come back telling us their hair finally feels like theirs again.

Frequently asked questions

What does Kérastase Première do?

Première is Kérastase's repair range for damaged, weakened hair. Built around glycolic acid (Acide Glycolique), it works on the structural side of damage — reducing breakage, smoothing split ends and restoring strength and elasticity, rather than just coating the hair to feel better short-term.

Is Kérastase Première good for colour-treated and bleached hair?

Yes. It's one of the ranges our colourists reach for most for lightened, colour-worn hair that has started to break or feel papery through the mid-lengths. For lightened blondes specifically, it pairs well with Blond Absolu for toning and nourishment.

What's the difference between Kérastase Première and Résistance?

Both target weakened hair. Première is the newer repair line led by glycolic acid, focused on breakage, split ends and fibre smoothing. Résistance is the long-standing strength-and-repair range for over-processed, fragile hair. Our colourists often compare the two depending on how the hair behaves in the chair.

How do I use the Kérastase Première range?

Build it as a small system: cleanse with the Première shampoo, then repair with the conditioner or mask (once or twice a week for actively splitting ends), and finish with a leave-in or serum to protect through heat and daily handling. If budget's tight, start with the mask and leave-in.

How long until I see results from Kérastase Première?

Give it a solid month. Hair rebuilds gradually, so the change shows over a few weeks of consistent use — most clients first notice less breakage on the bathroom floor and hair that holds its shape better between appointments.

Is Crew an authorised Kérastase stockist in NZ?

Yes. Crew Stylists is an authorised stockist of genuine Kérastase, so every product is the real thing, properly stored and current. We ship NZ-wide from our Queenstown salon, with free shipping on orders over $99.
