Kérastase Chronologiste Overnight Youth Hair Serum

The Kérastase Chronologiste Overnight Youth Hair Serum is a luxurious, overnight age-corrective leave-in serum infused with Pro-Xylane™ and Ochrophyta Algae. Specially engineered to work in harmony with your nighttime recovery cycle, this premium leave-in formula reverses the 5 signs of hair aging by addressing dryness, frizz, dullness, lack of volume, and brittle strands. It deeply hydrates, smooths, and builds body from root to tip, transforming fine or weakened hair into touchably thick, resilient locks with a completely weightless touch. Perfect as a nocturnal restorative treatment, it seamlessly prepares your hair for morning styling by providing robust 450°F heat protection against thermal damage.
