Kerastase Resistance Serum Extenioniste (Scalp and Hair Serum) 50ml

Kerastase Resistance Serum Extenioniste (Scalp and Hair Serum) 50 ml is a precision treatment engineered to boost vitality from root to tip. It nourishes the scalp while reinforcing each hair fiber, delivering visibly healthier, more resilient hair day after day.

What makes this serum unique

• Ceramide-based surface recovery: helps protect the hair fiber at the outer layer, restoring surface smoothness and resilience against daily wear and styling.
• Creatine-powered strength: an amino acid that penetrates the hair matrix to reinforce the internal structure, improving resistance to breakage and helping strands feel sturdier over time.
• Scalp-first approach: designed to nourish the scalp while supporting overall hair health, creating a healthier foundation for ongoing styling.

Why it matters for your hair

For hair that looks dull or feels fragile, this serum offers more than surface conditioning. By addressing both the scalp and the fiber, it helps reduce breakage from root to tip and promotes a softer, smoother finish that still holds volume and movement. The result is hair that not only looks stronger but also feels more resilient to daily styling stresses.

Who should use it

• Individuals experiencing scalp dryness or sensitivity who want a reinforcing treatment that supports hair strength.
• Anyone looking to improve hair resilience and reduce visible breakage, especially with regular heat styling or chemical treatments.
• Those seeking a targeted, leave-in serum that treats both the scalp and the hair fiber in a single step.

How to use

1. Apply a small amount of serum directly to the scalp at the crown and along partings.
2. Massage gently with fingertips to promote absorption and stimulate circulation.
3. Distribute any remaining serum through the lengths to ensure even coverage.
4. Style as usual. Use consistently as part of your regular hair care routine to maintain results.

What to expect

• Scalp feeling refreshed and nourished, not weighed down.
• Hair that feels soft, smooth, and visibly stronger with improved resilience.
• Enhanced foundation for daily styling, helping reduce breakage over time.

Why choose this treatment

Unlike generic serums, Resistance Serum Extenioniste blends ceramide‑based surface recovery with creatine’s deep reinforcement. This dual-action approach targets both the external hair surface and the internal structure, delivering a practical solution for healthier scalp health and robust hair fibers—without sacrificing a natural, touchable finish.
