Active Ingredients

Pro-Xylane

An advanced molecule born from green chemistry, derived from a natural sugar found in beech wood. A superstar in anti-aging skincare, it strengthens and deeply hydrates hair, plumping each strand for a fuller, thicker look, so aging hair feels healthier, stronger, and more youthful.

Ochrophyta Algae

A bio-sourced deep-sea algae, rich in antioxidants, minerals, and nutrients that help revitalize hair and the scalp as they age. It replenishes and protects against the daily stress that leaves hair looking dull and tired, so strands look revived, healthier, and full of youthful vitality.

Why it Works

Why the problem exists

You catch your reflection, and your hair just looks a little thinner and flatter than it used to. Hair ages the way skin does: over time, each strand grows finer and weaker, loses density, and holds onto moisture and shine less. So it can look tired and miss the body you remember.

Why this product solves it

This overnight serum works while you sleep to target age-related thinning. Pro-Xylane, a patented anti-aging molecule (the same kind used in skincare), helps rebuild and plump the fibre so strands feel thicker and stronger, while mineral-rich Ochrophyta algae (kelp) revitalizes and nourishes tired hair. Smooth one pump through your lengths at night, and it works while you sleep- no rinsing in the morning.

What to expect over time

You'll wake up to softer, shinier hair, and with regular nightly use, Kérastase measures strands about 5.7% thicker in diameter, 66% less frizz, and up to 92% stronger. It's a slow-build treatment, so the fuller, healthier feel really shows the longer you use it.
