Kérastase Elixir Ultime Refillable Oil – For Shine & Hydration

Kérastase Elixir Ultime Refillable Oil is the current version of the brand’s signature shine-focused hair oil. Its lightweight formula uses wild camellia to help smooth frizz, add shine, and provide heat protection without a heavy finish.

We tested this on thick, color-treated hair and found that a small amount on damp hair before blow-drying improved softness and surface shine while absorbing without obvious residue. The refillable format is a practical update for repeat users, and the signature Kérastase fragrance remains a defining part of the experience.

It is a premium purchase, but the concentrated formula means a bottle can last for months. It is best suited to dry, color-treated, or thicker hair types looking for a shine and smoothing finish.
