Kerastase: Choosing a Range by Hair Type, Building a Routine and Using Codes

Kerastase is the L'Oreal-owned professional hair-care brand sold in salons and through its own US site. It is organised into ranges, each aimed at a hair need: dryness, damage, color, frizz, thinning or scalp concerns.

A Kerastase order goes well when you pick the range that matches your hair's actual problem, buy the steps you need rather than the full regimen, and time purchases to its codes and gifts.

Choosing a Kerastase range

Nutritive is for dry hair, with versions for fine and thick textures.

Resistance targets damaged, weakened hair; it includes Ciment Thermique, a heat protectant.

Chroma Absolu is for color-treated hair, designed to help color last.

Blond Absolu is for lightened or blonde hair, including a purple product to counter brassiness.

Discipline is for frizz and humidity control.

Genesis targets hair fall caused by breakage, and Specifique and Symbiose focus on scalp concerns.

Curl Manifesto is for curly and coily hair.

Pick by your main issue. If your hair is both colored and dry, Chroma Absolu usually comes first, with a Nutritive mask as a second step.

Kerastase product names

Kerastase uses French names for steps. A Bain is shampoo; a Fondant is conditioner; a Masque is a mask; a Serum or Huile is a leave-in treatment or oil.

Elixir Ultime is Kerastase's famous hair oil line, and suits most hair types for shine and softness.

Read the hair type on each product page. Kerastase often makes the same range in "light" and "rich" versions.

Building a routine without overbuying

You don't need every step. Start with a Kerastase shampoo and one conditioner or mask from your chosen range.

Add a leave-in or oil if your ends are dry or you use heat tools. A heat protectant is worth it if you style with heat daily.

A mask once or twice a week is enough for most people. Use conditioner the rest of the time.

Kerastase products are concentrated. Use less than you would with a supermarket shampoo and a bottle lasts longer.

Sizes and value

Kerastase sells travel, standard and large refill or liter sizes for many products.

Once you know a Kerastase product suits your hair, larger sizes usually cost less per ounce. For a first try, a standard or travel size is safer.

Sets bundle a routine at a lower combined price than buying separately, and are good for trying a full range.

Hair fall and scalp concerns

The Genesis and Specifique ranges are cosmetic products for the look and feel of hair and scalp.

Sudden or heavy hair loss, patches of loss or a persistent itchy scalp should be seen by a doctor or dermatologist. Kerastase products can support care but do not treat medical causes.

Getting the most from each Kerastase product

Apply a Kerastase mask to towel-dried hair rather than soaking-wet hair, so the product isn't diluted, and leave it on for the time stated on the pack.

Focus conditioners and masks on the lengths and ends. Scalp products from the Specifique or Symbiose ranges are the ones meant for the roots.

Use oils and serums on damp or dry ends in small amounts. A pump or two of Elixir Ultime is usually enough for shoulder-length hair; more tends to weigh fine hair down.

If a Kerastase product stops giving the results it did, your hair may have changed. Color, heat styling and the seasons shift what it needs, so revisit the range choice rather than adding more steps.

Buying genuine Kerastase

Kerastase is sold through salons, selected retailers and its own US site. Products from unofficial marketplace sellers can be old stock, diverted salon stock or fakes, and there is little recourse if a bottle looks or smells wrong.

Buying from the Kerastase site or an authorized salon means fresh stock and a clear returns route. Check the current Kerastase return terms before opening anything, since opened beauty products are often treated differently.

If a price elsewhere is far below the Kerastase site on a current product, treat that as a warning sign rather than a bargain.

Where the Kerastase savings are

The 20% Kerastase code is the best percentage discount. Put it on the order with large sizes or sets, where it saves the most.

MYKER is a fallback if the 20% code is excluded from your items or expired.

The free travel-size Elixir Ultime mask is a good way to try the line. Use it on a small reorder where a percentage saving would be modest.

Kerastase usually allows one code per order, and codes may exclude new launches, sets or first-order-only offers. Check the cart before paying.

Common questions

Which Kerastase range is best for dry hair?

Nutritive, in the version for your hair thickness.

Is Kerastase worth it over drugstore brands?

Many people find it performs better and lasts longer because it is concentrated. Try a travel size first.

Can Kerastase stop hair loss?

Kerastase Genesis targets breakage-related fall. For real hair loss, see a doctor.

Where should I buy Kerastase?

From the Kerastase site, an authorized salon or a retailer the brand lists. Marketplace bargains carry a risk of old or fake stock.
