We have become accustomed to talking about longevity when it comes to skin, but hair deserves the same attention. With the launch of its Chronologiste Overnight Youth Serum, Kérastase is bringing this approach to hair care, exploring how we can maintain strength, shine and fullness as our hair changes over time.

Kérastase introduces its Chronologiste Overnight Youth Serum, bringing the science of hair longevity to an overnight treatment for stronger, shinier-looking hair.
The launch came to life at The Exchange TRX, where Kérastase hosted an exclusive pop-up featuring scalp scans conducted by The Soloists Salon. The consultations offered visitors a closer look at their scalp condition and a better understanding of their hair care needs. Izleen Izham, Shalma Aina and Bella Kuan were also part of the experience, discovering the new serum at the pop-up, while Kérastase made a striking statement by taking over the façade of TSLAW Tower.
At the heart of Chronologiste is Caviar of Longevity, a combination of Pro-Xylane and Ochrophyta Algae that Kérastase says works on both the scalp and hair. The approach addresses five visible signs of hair ageing: dryness, dullness, lack of volume, lack of thickness and frizz.
The latest addition, the Chronologiste Overnight Youth Serum, translates this philosophy into a nighttime ritual. Applied to dry or damp hair before bed, the leave-in formula delivers deep nourishment and lasting hydration without requiring a rinse. According to the brand’s clinical testing, it increases hair fibre diameter by 5.7 per cent after one use and 12.7 per cent after eight uses, while testing also recorded 66 per cent less frizz, 32 per cent more shine and 92 per cent less hair breakage.
Demi Moore, the face of Chronologiste, brings a personal perspective to the conversation. “My hair has always been a powerful part of who I am. When it feels strong and healthy, I feel more myself,” she says.
For Moore, whose long, dark hair has become a signature, the relationship between hair and identity is particularly resonant. Ultimately, Kérastase’s focus on hair longevity centres on maintaining its health, strength and vitality through every stage of life.
