SCIENCE
CAVIAR OF LONGEVITY
Continuous exposure to daily environmental and mechanical aggressions leads to a progressive ageing of the hair fibre, consequently contributing to an overall aged appearance.
To address these concerns, Kérastase has identified 5 signs of hair ageing - frizz, dullness, lack of thickness, lack of volume and dryness, and developed a targeted regimen, including an innovative night serum, designed to help reverse these signs.
KEY INGREDIENTS
Pro-Xylane™
A pioneering, eco-designed L’Oréal molecule that boosts essential Glycosaminoglycans (GAGs) to regenerate and revitalise the hair root.
Ochrophyta Algae
A biosourced, marine powered regenerating active that strengthens the scalp barrier.
