KERASTASE Premiere Anti-Frizz Hair Repair Serum | Bond Repair & Heat Protection

Salon-grade repair for all damaged hair types

Every day, hair endures heat, humidity, and environmental stress. The Kerastase Premiere Anti-Frizz Serum is a leave-in treatment designed to shield strands while delivering targeted repair. With a lightweight feel, it helps hair look smoother and more luminous as you style.

This serum acts as a protective veil, defending against heat up to 450F, resisting humidity, and taming frizz so hair maintains a controlled, polished finish from morning to night. You may notice a visibly reduced appearance of split ends and a stronger, shinier look with continued use, without weighing hair down.

How it works and what it contains

• Peptides help strengthen and smooth the hair shaft for a more cohesive texture.
• Glycine assists in reconnecting keratin links, supporting structural integrity and reducing breakage risk.
• Dual-action care protects against heat while reinforcing the strand from within for long-term resilience.

What to expect in real-life use

• Up to 3x smoother hair compared with unwashed hair, with a softer feel and easier styling.
• Visible reduction in the appearance of split ends and a stronger overall look over time.
• About 85% more shine compared with unwashed hair in typical usage conditions.

How to use

• Apply to towel-dried hair, focusing on mid-lengths and ends.
• Leave-in and proceed with blow-dry or air-dry for the preferred finish.

Included in the Kerastase Premiere Collection, this serum offers dual-action care designed to strengthen hair from the inside out while delivering a smoother, more polished exterior. It’s a practical daily step for those seeking manageability, shine, and resilience without sacrificing weight or movement.
