Damaged hair can look dull and frayed on the outside even when it's getting stronger underneath. Years of processing and hard water roughen each strand's surface and splinter the ends, and a rough, uneven surface scatters light instead of reflecting it, so hair looks flat and the ends look ragged and thirsty. All the repair in the world doesn't show if the surface isn't sealed and smooth.

This lightweight finishing oil is the last step in the Première routine, made with weightless oils and silicones that glide over the surface to seal it smooth. It wraps split, frayed ends to bind them down, lays the surface flat so light bounces back as glassy shine, and shields hair from heat when you style, all without any greasy weight. A pipette or two is all it takes to make repaired hair actually look repaired.

The shine is instant: one application and hair looks up to 4 times shinier, with sealed, smoother ends. Used regularly to finish your Première routine, the brand measures up to 92% fewer split ends and stronger-feeling hair. Because it shields against heat every time you style, your ends stay sealed instead of fraying further.
