Unlike any other serum, Elixir Ultime oil manages to pack a multitude of rich active ingredients into its melt-in-the-hand formula, concentrating on eliminating frizz, damage & split ends. Directions for use: For best results, apply a little Kérastase Elixir Ultime Serum Solide to dry hair after brushing & where possible, as a beauty touch-up as part of your day.

Do not apply to the roots.
