What this review covers
- Core families: Nutritive, Resistance, Blond Absolu and Genesis lines
- Formats: shampoos, conditioners, masks, serums and oils through salons and professional retailers
- Positioning: prestige salon
- Where it is sold: sold through salons, professional retailers and its online shop
- Start here: a core variant for salon buyers who want a diagnosed, concern-led hair routine
Verdict
Judged as a prestige salon range, Kérastase works best when bought from its core families, led by Nutritive, Resistance, Blond Absolu and Genesis lines. Diagnosis-led selling is central: lines are named for hair states, not just for a single benefit. Buy the variant that fits an existing routine, in a size that will be finished, and the brand does its job without fuss; buy on a limited variant alone and repurchasing becomes the weak point.
Pros
- Concern-led salon lines with detailed hair-type guidance
- Core families are easy to repurchase because they are sold through salons, professional retailers and its online shop
- A prestige salon range with choice across shampoos, conditioners, masks, serums and oils through salons and professional retailers
Cons
- Premium pricing and salon distribution narrow easy access
- Variant names matter: two nearby variants can differ in shade, scent or formula
- Limited additions may not be restocked in the same form
What the brand makes
The Kérastase range grew out of Paris in 1964, as a professional salon hair-care brand into a broad catalogue led by Nutritive, Resistance, Blond Absolu and Genesis lines. What holds it together is not one product but a shared approach: recognisable packaging, steady restocking, and variants aimed at different budgets and routines.
Range depth varies by store. A large retailer may carry the full spread of a family, while a smaller shop stocks only its most popular variants. Checking the brand's own listing before a trip saves a wasted journey when a specific shade, scent or size is the point of the purchase.
Formats and hair types
The practical question is format first, variant second. Kérastase offers shampoos, conditioners, masks, serums and oils through salons and professional retailers, and each format fits a different routine: a compact pack for a bag or a trip, a standard pack for a bathroom shelf, a larger pack for a household that goes through product quickly. Matching format to routine avoids half-used products left behind.
Who it is for
Expect the strongest fit for salon buyers who want a diagnosed, concern-led hair routine. The range rewards a buyer who wants options under one brand roof and does not want to hunt for stock. It is less about a single standout product and more about a dependable shelf of related choices.
Who should skip it
It is a weaker match where you want supermarket prices or a single all-purpose shampoo. In that situation, comparing one or two specialist alternatives side by side with a core Kérastase variant, rather than browsing the whole catalogue, gives a fairer test of whether the brand earns a place in the routine.
This is general information, not medical advice.
How to choose before you buy
Begin with what is already known: a shade, scent or formula that has worked, a sensitivity to avoid, a budget ceiling. Those three facts narrow a large catalogue to a short list quickly, and the remaining choice is usually between two or three close variants rather than dozens.
Finally, compare like with like on value: the same variant, the same size, across two or three sellers. Prices move by retailer and region, and no price is quoted here for that reason. A multipack only saves money if every unit in it is a variant that will actually be used.
This review draws on public brand information, not on product testing. Where a variant is limited or seasonal, treat restock as uncertain and prefer a core variant for a daily routine.
Frequently asked questions
What is Kérastase?

What products does Kérastase make?
The catalogue covers shampoos, conditioners, masks, serums and oils through salons and professional retailers. Nutritive, Resistance, Blond Absolu and Genesis lines are the families most stores carry, while other variants appear in fewer outlets.
Who is Kérastase for?
It suits salon buyers who want a diagnosed, concern-led hair routine. The range rewards a buyer who wants options under one brand rather than a single fixed product.
Who should skip Kérastase?
It is a weaker match where you want supermarket prices or a single all-purpose shampoo. That is a mismatch of range, not necessarily a fault in the product itself.
How much does Kérastase cost?
Pricing moves too much by store and region to quote usefully. Check two or three sellers for the same variant and size, and treat a single-store price as a snapshot, not a standard.
