Overnight Anti-Aging Hair Serum

The Kérastase Chronologiste Night Serum 30ml is an overnight regenerating leave-in serum that works while you sleep to visibly improve hair quality. This intensive anti-aging treatment helps combat dryness, frizz, loss of volume and lackluster hair, leaving strands stronger, softer and more radiant by morning.

The formula is enriched with Pro-Xylane™ and Alga Ochrophyta, highly effective actives that work overnight to plump the hair fibre and enhance hair appearance. The lightweight "quick-break" texture melts instantly into lengths and ends without weighing hair down, wrapping hair in the iconic Chronologiste fragrance.

Perfect as an overnight treatment for dry, dull, frizzy or mature hair.
