KÉRASTASE Strengthening Nutri-Fortifiant Shampoo for Weak, Damaged Hair — Hydrating & Anti-Breakage

This salon-grade formula combines Edelweiss native cells and ginger root to target hair weakened by mechanical and environmental stress. Designed for dry, fragile hair that tends to fall out due to breakage, the shampoo cleanses without stripping natural moisture and prepares hair for improved resilience. Its rich yet lightweight lather detangles and smooths the fiber so that hair feels softer and looks healthier over time when used regularly as part of the Genesis regimen.

How does this shampoo reduce hair breakage?

The formula reinforces the hair fiber by delivering nourishing ingredients that help fortify weak points along the strand. Regular cleansing removes buildup that can lead to tangles and mechanical damage during brushing, while the conditioning agents smooth cuticles to minimize friction.

• Contains ginger root extract to strengthen hair at the root and along the fiber.
• Edelweiss native cells help protect and fortify weakened strands.
• Gentle surfactants cleanse without over-drying, reducing breakage from brittleness.
• Detangling effect cuts down on mechanical damage during styling and combing.

Will it hydrate dry, frizzy hair without weighing it down?

Yes — the Nutrition-Fortifiant balance targets hydration while maintaining lightness so strands don’t become limp. Moisturizing agents smooth and plump the fiber surface, giving frizz control and slip for easier styling without a heavy residue.

• Hydrating ingredients lock in moisture for a softer feel.
• Light conditioning agents preserve volume and movement.
• Improves manageability so less product or heat is needed to style.

How should I use it for best results?

Apply to wet hair, massage into the scalp to create a gentle lather, then rinse thoroughly; repeat if hair is very dirty. For a complete routine, follow with the matching Genesis conditioner or mask to seal the fiber and maximize anti-breakage benefits.

• Use on wet hair; massage scalp for 30–60 seconds, then rinse.
• Repeat the wash for intensive clarifying on days with heavy product buildup.
• Pair with Genesis conditioner or serum to fortify and detangle after washing.

Is it suitable for color-treated or sensitive scalps?

The gentle cleansing base and nourishing actives make it generally compatible with color-treated hair, while the mild formula reduces harsh stripping. If you have a very sensitive scalp, patch testing is recommended and consult with your stylist if concerns persist.

• Formulated to clean without aggressive sulfate stripping.
• Helps maintain color vibrancy by avoiding over-drying of the fiber.
• Patch test recommended for highly reactive scalps.
