Kérastase

Professional luxury haircare with scalp-focused and strengthening formulas.

Kérastase has built its reputation as the gold standard in professional luxury haircare — a brand where formulation science meets salon experience. Founded in France and distributed exclusively through professional channels, Kérastase lines are designed around specific hair and scalp diagnoses: breakage-related hairfall (Genesis), moisture and repair (Nutritive), strand strengthening (Résistance), scalp health (Specifique), and more. Each product range is named and formulated for a precise concern, not a generic "moisturizing" or "strengthening" claim. The Genesis line — which includes the Genesis Serum Fortifiant — was developed specifically in response to hairfall caused by mechanical and chemical breakage rather than scalp conditions or androgenetic causes. Kérastase products contain fragrance as part of the signature salon experience, which is an important consideration for sensitive scalps. The brand is widely used in salons and is also available direct-to-consumer at a premium price point that reflects the formulation quality and professional heritage.

Frequently Asked Questions About Kérastase

What is Kérastase known for?
Professional-grade luxury haircare with targeted line architecture — each product range is formulated around a specific hair and scalp concern. The brand is known for the Genesis range (breakage-related hair fall, heat protection), Nutritive (dry hair, split ends, overnight hydration), Chronologiste (prestige anti-aging with Pro-Xylane and Abyssine), Gloss Absolu (anti-frizz and high shine across all formats), Spécifique (scalp balancing), and Elixir Ultime (iconic hair oil).
What is the Kérastase Genesis range for?
The Genesis range is specifically designed for hairfall due to mechanical and chemical breakage — not hormonal hair loss or androgenetic alopecia. It includes the Genesis Serum Fortifiant (daily scalp leave-in) and Genesis Defense Thermique (heat protectant blow-dry primer), creating a complete scalp-to-lengths anti-breakage system.
What is the Kérastase Chronologiste range?
Chronologiste is Kérastase's prestige anti-aging haircare line for hair that has lost softness, body, and luminosity over time. Key products include the Bain Régénérant Shampoo, the Hair Mask, and the Overnight Youth Serum — all featuring Pro-Xylane (L'Oréal's patented matrix-hydration active) and Abyssine (a marine deep-sea conditioning complex).
What is the Kérastase Gloss Absolu range?
Gloss Absolu is Kérastase's dedicated high-shine anti-frizz collection — delivering glass-like hair shine and frizz control across a full system: two shampoos for different hair types, conditioner, mask, leave-in spray, styling cream, glaze drops, and a hair perfume. Each product in the system layers onto the next for cumulative gloss results.
What is the Spécifique Bain Divalent shampoo for?
The Spécifique Bain Divalent is a dual-action balancing shampoo for the oily-roots-dry-ends hair type. Vitamin B6 regulates scalp sebum at the roots while Amino Acids protect the lengths from the purifying cleanse — allowing oily-scalp types to wash regularly without stripping their ends.
Is Kérastase good for sensitive scalps?
Kérastase products contain fragrance as part of the brand experience. For scalp sensitivity related to fragrance, proceed with caution and patch test. The Spécifique range is designed for sensitive scalp conditions but still contains fragrance — check individual product ingredient lists if fragrance sensitivity is a concern.
How does Kérastase compare to The Ordinary's scalp serum?
The Ordinary NMF + HA Scalp Serum addresses hydration-related scalp dryness with a minimal ingredient approach and no fragrance. Kérastase Genesis Serum Fortifiant addresses breakage-related hairfall and hair fibre strengthening with a professional-grade complex and the signature salon experience. They target different concerns and can be used as complementary products.
Where should I start with Kérastase?
Identify your primary hair concern first. For breakage and hairfall: Genesis Serum Fortifiant + Defense Thermique. For dry, frizzy hair: Nutritive 8H Night Serum. For aging hair: Chronologiste Shampoo + Mask + Overnight Serum. For glass-hair shine and anti-frizz: Gloss Absolu system (pick the shampoo for your hair type). For oily scalp with dry ends: Spécifique Bain Divalent.
