Resistance Serum Extentioniste is a leave-in hair serum specifically formulated to nourish brittle, damaged hair. It uses Kérastase's powerful ceramide complex and lipids to rebuild weakened strands from the inside, before sealing the cuticle to protect strands and prevent further breakage. Massaged into the scalp, it cleanses and stimulates the scalp area while defending against environment aggressors and pollutants. The result: more resilient, well-nourished and fabulously shiny hair.


  • Fortifies brittle, damaged fibres
  • Promotes elasticity and strengthens hair
  • Cleanses and nourishes the scalp


Apply up to three pipettes of the serum to the scalp area weekly or biweekly. Using your fingertips, massage into the scalp with circular motions to cover the whole scalp area.
