The Kérastase Chronologiste Trio 2026 Holiday Set offers a complete revitalising ritual for hair experiencing signs of ageing. Infused with high-performance actives, the three-piece collection works to restore bounce, shine, and softness to dry, dull lengths. Set Contents: Chronologiste Bain Mini 80ml This revitalising shampoo gently cleanses the scalp and lengths while infusing the hair with hyaluronic acid and abyssine. The gel-to-foam formula removes impurities and helps to shield the hair fibre against environmental aggressors for a stronger, more moisturised finish. Chronologiste Masque 75ml An intensely nourishing hair mask enriched with hyaluronic acid and abyssine to deeply condition dry and dull lengths. The rich formula detangles each strand, promoting improved manageability, bounce, and a softer feel. Chronologiste Overnight Youth Serum 90ml This intensive overnight leave-in treatment utilises pro-xylane and ochrophyta algae to revitalise the hair as you sleep. The fast-absorbing formula melts into the hair to significantly reduce frizz and boost shine by morning.
