KÉRASTASE Nutri-Fortifiant Strengthening Shampoo 16.9 fl oz — Sulfate-Free for Weak & Damaged Normal-to-Dry Hair

KÉRASTASE Genesis Nutri-Fortifiant Shampoo is a strengthening, nourishing cleanser formulated to gently purify the scalp and reduce hair breakage for weak or damaged, normal-to-dry hair.

This sulfate-free shampoo is designed to cleanse without stripping moisture while delivering fortifying nutrients that help hair resist fallout from mechanical stress like brushing. Paired in the regimen with the complementary Fondant Renforcateur conditioner, it aims to detangle, smooth and replenish hydration so strands look healthier and feel more resilient. The formula targets fragile fibers and scalp clarity to create a foundation for stronger-looking hair.

How does this shampoo reduce breakage during daily styling?

The Nutri-Fortifiant formula focuses on strengthening weakened hair fibers and improving manageability so combing and styling cause less mechanical damage. It replenishes lipids and moisture to reduce friction between strands and helps smooth cuticles for fewer snags.

• Fortifying ingredients reinforce fiber structure and elasticity.
• Hydrating agents reduce tangling and minimize friction when brushing.
• Gently clarifying surfactants remove buildup without drying hair out.
• Works well with conditioner to add slip for easier detangling.

What results can I expect after regular use?

With consistent use, hair appears less prone to breakage and feels softer and more manageable. Scalp clarity improves, which helps styling look cleaner and hair reflect more natural shine without feeling weighed down.

• Reduced visible fallout from brushing and styling over time.
• Smoother, hydrated strands with improved combability.
• Cleaner scalp and refreshed texture between washes.
• Enhanced shine and polished appearance when paired with the conditioner.

Is this shampoo suitable for my hair type and concerns?

It’s formulated for normal to dry hair that’s fragile or damaged and prone to falling due to weakness. The gentle cleansing system and nourishing actives make it a good daily or frequent-wash option for those seeking strength without stripping natural oils.

• Recommended for fragile, weakened, or chemically treated hair types.
• Effective for hair that tangles easily or loses strands from brushing.
• Not intended as a medicated hair-loss treatment—supports fiber resistance.
• Pairs with conditioners and treatments from the same line for best results.

How should I use this shampoo for maximum benefit?

Apply to wet hair and massage gently into scalp to lift impurities and distribute the formula along lengths. Rinse thoroughly and follow with the Fondant Renforcateur conditioner to detangle and seal hydration into the hair fiber.

• Use a coin-sized amount and lather at the roots, then work through lengths.
• Rinse completely and apply conditioner focusing on mid-lengths to ends.
• For fragile hair, avoid aggressive towel rubbing—pat dry and detangle with a wide-tooth comb.
• Use consistently to maintain strengthened, more resilient strands.

For a complete routine, use it alongside the Fondant Renforcateur conditioner and other KÉRASTASE Genesis products tailored to reduce breakage and enhance fiber nourishment.
