Details

Repair that lasts. Kérastase Première Sérum Filler Fondamental is a leave-in repairing serum that helps fill and smooth damaged areas, reduce frizz and restore shine, while protecting hair between washes. A Curious stylist favourite.

Key Ingredients, Explained

  • Citric acid: An organic acid (AHA) that captures and removes calcium build-up from hard water, inside and on the surface of the hair, to fight dullness and stiffness.
  • Glycine: An amino acid that penetrates the hair's inner layer once calcium is removed, helping reconnect broken bonds between keratin chains to reduce breakage.

Why We Love It

  • Leave-in repair.
  • Smooths and reduces frizz.
  • Restores shine.

Best For

Damaged, frizzy or brittle lengths.

How to Use

  1. Apply 2 to 3 pumps to damp lengths and ends.
  2. Style as usual. Do not rinse.

Curious Stylist Tip

Apply to damp hair before blow-drying, then finish dry ends with Huile Gloss.
