Therapist Serum

Discover Kérastase Double Serum Therapist, an ideal solution for very damaged and stressed fine or thick hair. This revolutionary serum rebuilds the hair fiber, providing a targeted response for hair that has reached an erosion level of 3-4. When your hair needs intensive treatment to deeply repair and smooth the fiber, Therapist Serum offers an effective solution. The secret lies in FIBRA-KAP™ technology, which fills in missing KAPs—micro-proteins crucial for keratin cohesion. By reactivating their synthesis, this serum restores vitality to the hair fiber. KAPs are often reduced due to repeated blow-drying, stress, and deficiencies, weakening the hair. This leads to deterioration, split ends, and breakage. Thanks to powerful FIBRA-KAP™ technology, this Kérastase serum for extremely damaged hair can deeply regenerate the hair fiber. Enriched with resurrection sap, it also restores essential hydration to the core of every hair. Double Serum Therapist is actually a fusion of two hair products. The first, a lightweight oil-based formula, provides deep hydration, while the second, a richer cream texture, targets damaged ends. The result is spectacular: split ends are repaired, and the hair fiber regains its natural smoothness. The results are quickly noticeable: your hair comes back to life, becoming soft to the touch and incredibly shiny. Using Double Serum Therapist is simple and effective. Apply it to wet hair before blow-drying or as a finishing touch on dry hair. As an added bonus, this serum provides heat protection up to 230°C and halves drying time. Give your hair the attention it deserves with Kérastase Double Serum Therapist for deep repair and striking shine.
