Why Kérastase Dominates the Damaged Hair Market

Before diving into specific product recommendations, understanding what sets Kérastase apart in the luxury haircare space helps explain why these products consistently deliver superior results for damaged hair.

Founded in 1964 by French hairstylist François Dalle, Kérastase was created specifically for salon professionals. This heritage ensures:

• Concentrated formulations designed for maximum efficacy
• Professional-grade ingredients not found in mass-market products
• Targeted solutions for specific hair damage types
• Salon-tested protocols for optimal results
