Ingredients: AI-inferred — not yet verified
Formulation inferred from manufacturer published ingredient lists. Kérastase Elixir Ultime is a classic leave-on hair treatment providing high shine, smoothness, and heat protection through a blend of volatile silicones and rich plant oils. While effective cosmetically, its score is impacted by environmental persistence of cyclic silicones (D5) and fragrance allergens.

Kérastase Elixir Ultime is a highly effective styling oil for shine and heat protection. If you prioritize immediate cosmetic finish and do not have fragrance sensitivities, it is safe and performant. However, those seeking eco-friendly or silicone-free alternatives may prefer plant-based oils.
Be cautious if
Individuals with fragrance allergies, sensitive scalps, or those intentionally avoiding cyclic silicones due to environmental bioaccumulation.
Against your clean standard
Conditional — Passes general human safety standards at permitted concentrations, but fails strict eco-clean criteria due to non-biodegradable cyclic silicones and undisclosed synthetic fragrance.

Does Kérastase Elixir Ultime L'Huile Originale Hair Oil contain parabens, sulfates or fragrance?
A straight yes or no for the ingredient groups people most often want to avoid, checked against this product's published formulation.
