KÉRASTASE Genesis Hydra-Fortifiant Shampoo Refill 16.9 fl oz — Silicone-Free Strengthening & Hydrating

Kérastase Genesis Hydra-Fortifiant Refill is a silicone-free strengthening shampoo that hydrates and fortifies weakened, breakage-prone hair while clarifying the scalp.

This refill-size shampoo blends Edelweiss native cells and ginger root extract in a lightweight, sulfate-free base tailored for fine to greasy hair. It gently cleanses buildup, delivers moisture where hair needs it, and helps make strands more resistant to mechanical stress. The formula avoids silicones for a natural-feeling finish and is offered in a 16.9 fl oz refill pouch to reduce packaging waste.

How does this shampoo reduce hair breakage without weighing hair down?

The Genesis Hydra-Fortifiant formula targets both scalp and fiber: ginger root helps strengthen the hair at its base while Edelweiss cell extract supports fiber resilience. Because it’s silicone-free and formulated for fine or oily hair, it restores hydration without leaving residue that would flatten the hair.

• Ginger root extract: supports fiber strength at the root.
• Edelweiss native cells: protect and fortify hair structure.
• Light cleansing base: removes excess oil and impurities.
• Silicone-free finish: maintains natural volume and movement.

Will this work on color-treated or fragile hair?

While this shampoo is designed to be gentle, it focuses on strengthening and hydration rather than color protection. Its mild cleansing action suits delicate strands and reduces friction during mechanical styling, which can lower the chance of breakage for fragile or chemically treated hair.

• Mild surfactants: clean without harsh stripping.
• Strengthening actives: help reinforce weakened fibers.
• Compatible with regular color care routines when followed by appropriate conditioners or masks.
• Best paired with complementary Kérastase Genesis products for targeted color and damage concerns.

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

Pour the refill into your existing Kérastase bottle or a pump dispenser, then apply to wet hair focusing on the scalp and roots. Massage to work up a gentle lather, rinse thoroughly, and follow with a strengthening conditioner or serum for mid-length and ends.

• Use a small amount for fine hair; increase if hair is thicker.
• Massage gently to avoid extra mechanical stress on fragile strands.
• Rinse completely to prevent buildup and preserve lightness.
• Refill pouch reduces single-use plastic and is cost-effective.

What kind of results can I expect over time?

With consistent use, hair typically feels cleaner, more hydrated where needed, and better able to withstand daily styling. While immediate smoothing or shine will vary by hair type, ongoing use supports reduced fiber weakening and a fuller, more resilient feel.

• Cleaner scalp and reduced excess oiliness.
• Improved strand resistance to breakage from brushing and styling.
• Maintained lightness and natural movement thanks to silicone-free formulation.
• Refill format offers economical ongoing maintenance.

Who is this for: Kérastase Genesis Hydra-Fortifiant Refill is intended for people with fine, oily, or weakened hair who want a strengthening shampoo that hydrates without heaviness. It suits those seeking a salon-grade refill option and anyone aiming to reduce packaging waste while maintaining daily care for breakage-prone strands. If your priority is color protection or ultra-rich conditioning, pair this shampoo with a dedicated color-care conditioner or a targeted mask from the Kérastase range.
