Kérastase Première Sérum Filler Fondamental – Lightweight Repair & Shine Serum for Damaged Hair

Available in Canada at Curious Salons

For
Damaged, dull, brittle, or calcium-stressed hair needing softness, hydration, frizz control, and a lightweight, luminous finish.

Description
A featherlight veil of restoration. Kérastase Première Sérum Filler Fondamental is a leave-in repairing serum designed to hydrate, smooth, and protect hair weakened by calcium buildup and damage. Its fluid texture absorbs instantly, delivering weightless moisture while sealing the fibre for effortless shine and softness.

Enriched with citric acid, glycine, and smoothing actives, this serum helps preserve the hair’s suppleness after decalcifying treatments, protecting the fibre from humidity, dryness, and heat styling. Perfect for hair that breaks easily, feels stiff, or looks dull — especially in Canada’s hard-water regions — it leaves hair silky, resilient, and beautifully refined.
