The Story

A concentrated overnight serum formulated to restore and strengthen bleached or colour-treated hair. High‑concentration hyaluronic acid replenishes moisture while Edelweiss extract supports fibre resilience. Designed for hair weakened by lightening, the lightweight texture absorbs without residue to reduce breakage and help prevent split ends — a nightly ritual for smoother, stronger lengths by morning.

Apply a few pumps to towel-dried or dry lengths and ends before bed. Distribute evenly; do not rinse. Style as usual in the morning. Use nightly for best results.

Formulated around high‑concentration hyaluronic acid to draw and retain moisture within the fibre. Edelweiss extract provides antioxidant support to sensitised strands. Free‑weighting texture ensures even distribution and absorption for effective overnight repair.

At Ellie Jules, every order is prepared with care to ensure it arrives as beautifully as it was chosen. Enjoy complimentary shipping on orders over €100, with secure, reliable delivery across our full range of jewelry, fragrances, skincare, accessories, and home accents.

About Kerastase

Kérastase: Pioneers of Luxury Hair Care

Provenance: France

Kérastase is a French hair care house rooted in professional salon expertise, with a catalogue built around shampoos, conditioners, masks, oils, serums and targeted treatments for varied hair and scalp needs. The brand’s official site presents it as expert hair care for women and professional hairdressers worldwide, reflecting a category positioned at the intersection of performance and ritual.

Its philosophy is treatment-led rather than decorative: ranges such as Blond Absolu, Chronologiste, Genesis, Curl Manifesto and Densifique are structured around specific hair concerns, from strength and density to colour care and nourishment. Within this grounded assortment, Elixir Ultime stands out as the brand’s iconic hair oil, a defining expression of Kérastase’s focus on finish, touch and visible refinement.

Kérastase matters because it helped establish premium hair care as a discipline of diagnosis, targeted formulas and salon credibility. It remains a reference point for consumers seeking technically informed care with a distinctly French provenance and professional heritage.
