Kérastase is a French haircare house rooted in professional salon expertise, and its ranges are organised by hair need rather than by look. To choose well, start with what your hair needs most, whether that is care for blonde or coloured hair, moisture for dry hair, or body for fine hair, then pick a shampoo, a conditioner or hair mask and a serum from the same range.
The Kérastase Approach to Haircare
Kérastase describes itself as expert haircare for women and for professional hairdressers. Its catalogue is built around shampoos, conditioners, hair masks, oils, serums and targeted treatments, and its thinking is treatment-led rather than decorative. Each range is shaped around a particular concern, from strength and density to colour care and nourishment, which is why the range name on the bottle matters more than the product type.
The house also gives weight to finish and touch. Elixir Ultime, the range behind its best-known hair oil, is the clearest expression of that: care that is meant to feel as good in the hand as it looks in the mirror. The practical lesson is simple. Read the range name first, decide whether it matches your hair, and only then choose the format.
Shampoo and Hair Masks for Blonde and Coloured Hair
Lightened, highlighted and coloured hair asks for gentler care, and Kérastase has a range for each. Blond Absolu is for blonde hair. The Blond Absolu Bain Ultra-Violet Shampoo is a violet shampoo made to help neutralise unwanted brassiness in blonde and grey hair, with hyaluronic acid and edelweiss. The Masque Ultra-Violet Hair Mask follows the same idea in a rinse-out mask, helping to counter brassy undertones for a cooler finish. To finish, the Blond Absolu Cicaplasme Leave-In Hair Serum pairs hyaluronic acid with edelweiss in a lightweight formula you do not rinse out.
If your hair is coloured rather than lightened, look to Chroma Absolu. The Nourishing Chroma-Respect Shampoo, part of that programme, is a creamy gel shampoo for coloured hair of medium to coarse texture, made to cleanse gently while caring for the colour. Violet formulas are best kept for blonde and grey hair; for other shades, a colour-care shampoo is the more useful everyday choice.

Shampoo and Hair Masks for Dry Hair
Dry hair needs nourishment without heaviness, so the texture of each step matters. The Nutritive Bain Satin Shampoo is a daily shampoo for dry hair with a lightweight, hydrating feel. The Niacinamide and Glycerin Nourishing Shampoo is made for coarse, dry hair and comes with a controlled-dose pump. For a weekly treatment, the Spécifique Masque Hydratant Amino Acid and Ceramide Hair Mask has a creamy texture for dry, sensitised lengths.
If dryness shows mostly as dullness, the Elixir Ultime Le Bain Huile Sacrée De Marula Shampoo is the house's oil-infused wash for hair that needs renewed shine. It brings the Elixir Ultime idea of finish and shine into the wash itself, which suits anyone who likes the feel of an oil but prefers a simpler routine.

Fine Hair and Curly Hair
Fine hair is easily weighed down, so lighter formulas work best. The Volumifique Bain Volume Système Ampliflex Shampoo is a lightweight shampoo designed to help fine hair feel fuller and more buoyant. Densifique is the range for hair that looks lacking in density: the Densifique Densimorphose Hair Treatment Mousse is a light foam that supports body and substance.
Curly hair usually wants the opposite: more moisture and more slip. Curl Manifesto is the range for it. The Curl Manifesto Shampoo is a creamy shampoo for wavy, curly and afro textures that cleanses without stripping. The Curl Manifesto Fondant Hydratation Essentielle Conditioner brings softness and hydration to curly, very curly and coily hair, and helps support curl definition.

Building a Routine: Shampoo, Conditioner or Mask, Serum
A good routine has three steps. First, a shampoo chosen for your scalp and hair need. Second, a conditioner on most washes, or a hair mask when your lengths need more. Third, a leave-in serum or oil on towel-dried or dry lengths to finish. Staying within one range keeps the textures and intentions consistent, which is how the house organises its care.
Résistance shows how this works for hair that feels over-processed or weakened. The Résistance Bain Thérapiste Shampoo has a balm-in-shampoo texture for very damaged lengths. The Résistance Masque Extentioniste Hair Mask is the richer rinse-out step for lengths that need extra care. The Résistance Sérum Thérapiste Hair Serum is a leave-in for lengths and ends, finishing the routine with a smoother look. If you blow-dry, the Résistance Extentioniste Thermique Length Caring Gel Cream is a lightweight leave-in made to care for lengths during heat styling, applied before the dryer.

How Often to Use a Hair Mask
A hair mask takes the place of your conditioner, not an extra step after it. For most hair, once a week is a sensible starting point. Dry, lightened or coloured hair may enjoy a mask twice a week, while fine hair is often happier with a mask once a week, applied to the mid-lengths and ends only, keeping it away from the roots.
Apply a mask to clean, towel-dried hair so it is not diluted, comb it through, and leave it for the time given on the pack before rinsing well. If your hair begins to feel heavy or limp, use the mask less often and return to your conditioner in between. The directions on each product always come first.
Choosing a Kérastase Hair Care Set as a Gift
Haircare is a personal gift, so the safest choice is a set built from one range. If you know the person's hair, choose the range that matches it: Blond Absolu for a blonde, Curl Manifesto for curls, Nutritive for dry hair. A shampoo and a hair mask from the same range make a considered pair, and a serum or oil turns it into a full routine.
If you are unsure of their hair type, K Soleil is an easy choice for someone who spends time in the sun. The K Soleil Bain Après-Soleil Eau de Coco Shampoo gently cleanses hair exposed to sun and heat, the K Soleil Masque Après-Soleil Eau de Coco Hair Mask is a rich cream for lengths after days outdoors, and the K Soleil Huile Sirène Hair Oil Mist is a bi-phase mist that refreshes lengths in one quick spray. Together they make a summer set that suits a holiday or a birthday in the warmer months.
