The new standard: hair longevity

Rob Peetoom

Longevity for your hair, or in plain English: hair vitality. Research shows that women over 40 are happier than ever and also look younger than previous generations. They wear their hair longer, radiate more self-confidence, and are no longer dictated by age. Longevity is the new standard: not aging, but improving. And this doesn't just apply to your skin. Because your hair ages too: it becomes thinner, drier, duller, and coarser. Chronologiste was developed to reverse exactly that.

Chronologist resets your hair

Your hair tells the story of your life. Genetics, years of coloring or bleaching, hormonal changes like pregnancy, sun exposure, pollution, and stress all leave their mark. This manifests as frizz, loss of thickness and volume, dryness, dull shine, and a sensitive, dehydrated scalp.

Chronologiste works with two powerful ingredients that translate skincare science into hair care: pro-xylane and ochrophyta algae. Together, they reverse the signs of hair aging and boost cellular activity for optimal hair health.

Overnight wonder

The newest addition to the Chronologiste routine is the Overnight Youth Serum. A lightweight night serum for all hair types that reverses the signs of aging overnight. You'll wake up with hair that feels fuller and softer, 92% stronger, and 62% softer. It also provides heat protection for styling the next morning, without the need to reapply the serum. It carries Chronologiste's signature scent, a delicate blend of freesia and rose, and is the perfect addition to your hair vitality routine.

Demi Moore for Kérastase

At 63, Demi Moore is the new face of Kérastase, and the choice is telling. Long, shiny hair that defies the test of time. A look that belies her age. Moore isn't just the face of a brand; she's evidence of a movement. The woman who ages on her own terms, with hair that only gets better with age. Exactly what Chronologiste promises.

Time is on your side.

The updated Chronologiste line proves that your hair's best years are yet to come. With the updated Chronologiste line, Kérastase gives you the tools to actively reverse the signs of hair aging, night after night. Try it now in all Rob Peetoom salons, or view the collection online.
