Redken vs Kérastase: Two different philosophies.
Both worth your consideration.

Redken and Kérastase share a parent company — but that's where the similarity ends. They occupy different price points, different philosophies, and address hair concerns with meaningfully different ingredient strategies. Knowing which to use (and when to use both) is the difference between a routine that maintains your hair and one that genuinely transforms it.

THE ZENNKAI PERSPECTIVE

Same parent company. Completely different job to do.

redken built its reputation on accessible, protein-rich professional care that delivers real results for everyday hair. kérastase built its reputation on solving the hair problems that other brands couldn't. after 40 years carrying both, our take: start with redken if you're building a routine. reach for kérastase when the routine stops being enough.

Redken vs Kérastase for Metro Vancouver Hair

In Metro Vancouver, the Redken vs Kérastase decision often comes down to severity of concern and how Vancouver's specific environment is affecting hair. For colour-treated clients, Redken Color Extend Magnetics' EDDS chelating technology is one of the few daily shampoos specifically formulated to remove calcium, copper, and iron from Vancouver's tap water that accelerate fade — uniquely effective for Vancouver's water chemistry. Kérastase Première addresses the same mineral damage at a deeper structural level for hair where buildup has caused cumulative bond damage. For frizz in Vancouver's coastal humidity, Kérastase Discipline provides multi-day resistance on thicker hair; Redken Frizz Dismiss handles daily management across hair types.

A Note from our Founder

"I've sold both Redken and Kérastase since the early days of Zennkai, and the question I get most often from clients is whether the price difference is worth it. The honest professional answer: it depends on the concern. Redken built its reputation on accessible, science-backed professional care that delivers real results for everyday hair — the Acidic Bonding Concentrate range is genuinely excellent and works for most clients. Kérastase built its reputation by solving the hair problems that other brands cannot — Chronologiste for density loss, Première for severe damage, Genesis for hair-thinning concerns. My recommendation: start with Redken when you're building a daily routine. Reach for Kérastase when the routine stops being enough. The clients who get the strongest results often layer both — a Redken daily system with a Kérastase weekly mask for whatever advanced concern they're managing."

FREQUENTLY ASKED QUESTIONS

Is Redken or Kérastase?

Both brands are owned by L'Oréal and deliver professional-grade results, but they serve different priorities. Redken is protein-focused, widely accessible, and built for targeted concerns at a lower price. Kérastase is clinically precise, formulated with pharmaceutical-grade actives, and designed for deep progressive transformation. For everyday professional care, Redken is excellent value. For a persistent specific problem, Kérastase is the specialist.

Is Kérastase worth the extra cost over Redken?

If you have a specific hair concern — thinning, severe damage, colour longevity, or aging hair — Kérastase's targeted clinical formulations often justify the premium. Redken delivers strong results at a more accessible price and is the better choice for general maintenance, volume, or budget-conscious professional care. Many clients use both: Redken for daily washing and Kérastase for intensive weekly treatment.

Can I use Redken and Kérastase together?

Yes — and this is a common approach among professional clients. Pairing a Redken shampoo and conditioner with a Kérastase treatment masque gives you professional daily cleansing at a reasonable price point, with the benefit of clinical treatment on wash days. Both are L'Oréal professional lines formulated to compatible standards.

Which brand is better for colour-treated hair?

Both brands have strong colour-care lines. Redken Color Extend Magnetics uses an anionic active system to lock in colour molecules and extend vibrancy between services. Kérastase Chroma Absolu and Blond Absolu use patented Chroma-Captive technology alongside ceramides and hyaluronic acid for more intensive colour protection and fibre repair. For moderate colour maintenance, Redken is excellent. For heavily processed, frequently coloured, or bleached hair, Kérastase typically delivers more targeted results.
