A finishing serum for renewed hair. Kérastase Résistance Sérum Thérapiste is a dual-phase repairing serum for very damaged and over-processed hair. It instantly repairs and reinforces the fibre, seals ends and protects against blow-dry damage and split ends, with heat protection up to 230°C (450°F). 30 ml. A Curious stylist favourite.

Key Ingredients, Explained

Fibra-Kap™: A complex of 6 amino acids and a wheat protein derivative that helps compensate for the proteins very damaged hair has lost, restoring strength and elasticity.
Sève de Résurrection (resurrection plant extract): From Myrothamnus flabellifolia, a plant known for its regenerating power, to help revitalize weakened hair.

What It Does

Heat protection up to 230°C (450°F).
Repairs, reinforces and resurfaces the fibre.
Seals ends and protects against split ends.
Makes blow-drying up to twice as fast, with a smooth, shiny finish.

Why We Love It

Tames flyaways on dry hair.
Small bottle, a little goes a long way.

Best For

Very damaged, over-processed hair, especially thick hair that is heat styled.

How to Use

Apply 1 to 2 pumps to washed, towel-dried hair.
Work through mid-lengths and ends.
