Krastase Resistance Serum Extentioniste Fortifying Leave-In Serum for Stronger, Healthier Hair

Give your hair the strength it needs to grow long and strong with the Krastase Resistance Serum Extentioniste, a concentrated leave-in treatment designed to protect and reinforce weak, breakage-prone strands.

Infused with powerful ceramides, this lightweight, non-greasy serum helps to seal the hair cuticle, while lipid-based ingredients create a smooth, fortified surface. The formula works from root to tip to help rebuild the hair fibre, delivering strength, resilience, and visibly healthier lengths.

Applied directly to the scalp and hair, the serum forms a protective barrier against environmental stressors, while gently cleansing away impurities to promote a fresh, clean feel. Ideal for anyone looking to support healthy hair growth and reduce split ends and breakage.
