A Second Life: Kerastase Resistance Therapiste

Twenty years ago, Kérastase created Résistance to empower women to take better care of their hair. Now, Kérastase is ushering in a new era for hair care with Résistance Thérapiste, writes Chloe Falivene.

Clients are frequently torn between their desire to create beautiful looks and their guilt at all the damage over-processing can cause. Colour treatments and styling tools provide glamour – but at a price, with split ends and brittle hair worsening over time. That’s where Résistance Thérapiste comes in.

Soin Premier

Promising complete renewal of stressed or damaged hair, Résistance Thérapiste is the culmination of 15 years of research. Studies revealed that hair treated with Résistance Thérapiste products had 120% more resistance and a 75% reduction in split ends. The new line combines a pioneering scientific discovery about hair structure with the regenerative power of an ancient plant to deliver results in as few as 10 applications.


L’Oréal expertise has discovered that hair is composed of more than just ceramide and keratin. In fact, Keratin Associated Proteins (KAPs) link keratins together, providing an amazing 50% of hair’s overall structure. Damage breaks down these critical proteins, slowly destroying the structural integrity of each follicle. Résistance Thérapiste rebuilds hair fibre with Fibra-Kaps, a complex designed to compensate for KAP loss. The innovative compound combines a gluco-peptide, a wheat protein derivative, and 6 amino acids that attach themselves to damaged hair and activate KAP synthesis, restoring uniformity and smoothness.


To further promote regeneration, Kérastase has unlocked the secrets of Myrothamnus Flabellifolia, known as the “resurrection plant.” Myrothamnus grows in arid conditions, and can survive even the most severe droughts. Once the rain comes, the plant begins a second life. From this plant comes the Séve de Résurrection (resurrection sap) that Résistance Thérapiste uses to revive hair.

Serum Therapiste

The line includes four new products containing both the Fibra-Kaps complex and the Séve de Résurrection:

1. Soin Premier Thérapiste – Used pre-shampooing for clients with fine hair, it’s formulated to bind hair for protection during washing.
2. Bain Thérapiste – This semi-solid gel with cationic polymers boosts repair power in fine and thick hair.
3. Masque Thérapiste – The rich texture of this Masque fuses onto thick hair to fill it with reparative complexes.
4. Sérum Thérapiste – The last step for both fine and thick hair, this thermo-protective serum moisturizes and provides a topcoat to treat and seal follicle ends.

Kérastase has hand-picked international model Cameron Russell (featured in Vogue, Harper’s Bazaar, and Elle, among others) as the muse of the new campaign. Russell’s fantastic career and positive attitude embody the refreshing and restorative aspects of Résistance Thérapiste. Committed to making a difference in the world, Russell’s courageous TEDx presentation on beauty is one of TED’s 20 most popular talks of all time.

The Résistance Thérapiste collection will be available in salons from August. For more information, visit
