KÉRASTASE Genesis Hydra-Fortifiant Strengthening Shampoo Refill 16.9 fl oz – Lightweight Hydration & Breakage Reduction

Kérastase Genesis Hydra-Fortifiant Shampoo Refill is a gentle, strengthening cleanser that hydrates and fortifies weakened, fine or greasy-prone hair while helping reduce breakage during daily styling.

This refill-size Bain Hydra-Fortifiant delivers Kérastase’s signature blend of Edelweiss Native Cells and Ginger Root to clarify the scalp, add lightweight moisture and improve hair fiber resilience. Formulated to suit fine or oily scalps, the shampoo cleans without weighing hair down and pairs best with Fondant Renforcateur for added body and reinforcement.

How does this refill make hair feel and behave after washing?

After using the Hydra-Fortifiant refill, hair feels softer and more manageable with a lifted, lightweight finish. The formula balances hydration and clarity so strands avoid the heavy, limp feeling typical of richer conditioners.

• Gentle cleansing removes oil and impurities without stripping.
• Immediate hydration leaves hair soft to the touch.
• Lightweight texture maintains natural movement and volume.
• Paired use with Fondant Renforcateur enhances plumpness.

Will this help reduce breakage and hair fall during styling?

The shampoo is designed to strengthen the hair fiber and lower the chance of breakage by improving elasticity and resilience from root to tip. While not a medical treatment for hair loss, it supports healthier strands that resist snapping under tension and styling.

• Edelweiss Native Cells protect and bolster the fiber structure.
• Ginger Root helps reinforce the hair surface and scalp clarity.
• Regular use decreases the mechanical damage associated with brushing and heat.

How should I use the refill to get the best results?

Dispense the refill into your original pump bottle or shampoo container before use to maintain product stability and packaging sustainability. Work a small amount through wet hair, lather, then rinse; follow with Fondant Renforcateur for extra strengthening and volume.

• Refill into the original Kérastase bottle for accurate dosing.
• Apply to scalp and lengths, massage gently to activate actives.
• Rinse thoroughly and finish with the complementary conditioner.

Is this formula suitable for my hair type and routine?

Genesis Hydra-Fortifiant is aimed at people with weakened, fine or oil-prone hair who want a lightweight strengthening shampoo. It fits easily into daily or frequent washing routines and is compatible with styling products and heat tools when used alongside strengthening treatments.

• Best for fine, weakened, or greasy scalps seeking strength.
• Safe for color-treated hair when used as directed.
• Works well with additional Kérastase Genesis products for cumulative benefits.

Who is this for: This 16.9 fl oz refill is ideal for someone who regularly washes fine or oily hair and wants to replace the single-use bottle habit with a sustainable option without sacrificing performance. If you’re aiming to fortify fragile strands, reduce breakage during styling, and keep hair lightweight and hydrated, this is formulated to support those goals when used as part of the Genesis regimen.
