FAQ

HOW DOES KÉRASTASE SCIENTIFICALLY DEFINE HAIR AGING?
Kérastase defines hair aging as a process where the hair fiber undergoes diverse modifications due to both intrinsic biological factors and extrinsic environmental aggressions. This leads to a degradation of structural integrity, surface properties, and changes in composition, resulting in both invisible root causes (e.g., DNA instability, cell senescence, chronic micro-inflammation) and observable cosmetic attributes such as dryness, dullness, frizz, and changes in volume and thickness.

WHAT ARE THE SPECIFIC COSMETIC SIGNS OF HAIR AGING THAT CHRONOLOGISTE TARGETS?
Chronologiste targets five specific cosmetic signs of hair aging: dryness, dullness, frizz, lack of volume, and lack of thickness. These manifestations are linked to compromised smoothness, decreased hydration, and alterations in fiber structure.

WHAT IS THE CORE SCIENTIFIC PRINCIPLE OF THE CHRONOLOGISTE RANGE?
The core scientific principle is the “Science of Hair Vitality,” an approach that moves beyond simply reversing visible signs of aging. It employs a dual-action strategy to “Reverse” existing visible signs and “Reboost” cellular activity. This aims to work with the hair’s biology to address the invisible root causes of hair aging, thereby prolonging the hair’s beauty health-span and enduring vitality.

HOW DO PRO-XYLANE™ AND OCHROPHYTA ALGAE WORK TOGETHER IN CHRONOLOGISTE?
These two key ingredients form the “Caviar of Enduring Hair,” providing synergistic action. Pro-Xylane™ primarily influences hair density and scalp cellular dynamics, while Ochrophyta Algae contributes hydration, elasticity, and environmental protection. Their combined action comprehensively addresses the multifactorial aspects of hair aging at both the follicular and fiber levels, leading to an optimized scalp microenvironment and reinforced hair fiber architecture.
