Elixir Ultime L'Huile Originale — Reddit Reviews
by Kérastase
Updated November 10, 2026
Silicone-rich smoothing serum for frizz and shine; overapplication flattens waves.
What the community says
A silicone-forward finishing serum with dimethicone, botanical oils, and fragrance, meant for mid-lengths and ends after styling. Fine, dry, frizz-prone hair may love the gloss and tiny-dose slip, but roots and loose waves can go flat.
