KÉRASTASE Genesis Hydra-Fortifiant Shampoo for Weak or Damaged Hair — 8.5 fl oz, Silicone-Free Strengthening & Hydrating

KÉRASTASE Genesis Hydra-Fortifiant Shampoo is a silicone-free daily cleanser formulated to gently remove oil and buildup while strengthening hair prone to breakage from brushing.

This shampoo is part of KÉRASTASE's Genesis range and combines ginger root and native edelweiss cells to support fragile strands that suffer from mechanical damage and oilier scalps. It’s designed for everyday use on normal, oily and combination hair types and works best when paired with the full Genesis regimen—conditioner and serum—to help manage detangling, nourishment, and scalp clarity.

How does this shampoo help reduce breakage during brushing?

The formula focuses on reinforcing weakened fibers to lower the risk of breakage caused by mechanical stress like brushing. It cleanses without stripping, which helps hair maintain hydration and flexibility, making strands less likely to snap when combed.

• Contains ginger root to support scalp health and reduce sebum-related friction.
• Native edelweiss cells help fortify the hair fiber’s surface for improved resilience.
• Lightweight cleansing removes buildup that can make hair stiff and prone to snapping.

Will this work for oily scalp or fine hair?

Yes—this shampoo is formulated for normal, oily and combination scalps and is well-suited for thin or fine hair that needs gentle care. Its balanced cleansing action removes excess oils and pollutants that weigh down fine strands without adding silicones that can create residue.

• Gently lifts sebum and environmental particles from the scalp.
• Silicone-free formula avoids heavy buildup that flattens fine hair.
• Helps restore a clean, lightweight feeling to roots for better volume.

How should I use it for best results in my routine?

Apply on wet hair, lather, rinse, and repeat if needed—following with a Genesis conditioner maximizes detangling and nourishment. Regular use as part of a targeted routine gives the best outcome for reduced breakage and easier styling.

• Use daily or as often as you normally wash hair for consistent scalp clarity.
• Pair with Genesis conditioner and serum for deeper fiber reinforcement.
• Rinse thoroughly and avoid contact with eyes; rinse immediately if contact occurs.

Is this shampoo safe for color-treated or heat-styled hair?

The gentle, non-silicone formula is compatible with color-treated and heat-styled hair because it cleans without harsh stripping or heavy residues. By improving detangling and reducing breakage risk, it helps protect styled hair from additional mechanical stress.

• Non-stripping cleansing supports color longevity by avoiding aggressive detergents.
• Strengthening agents help hair withstand heat styling and daily handling.
• Follow with conditioner and protective treatments from the Genesis line for optimal care.

Who is this for: KÉRASTASE Genesis Hydra-Fortifiant Shampoo is aimed at people with thin, fine, oily, or combination hair that shows signs of mechanical damage—especially breakage from brushing. It’s a daily-use option for anyone seeking lightweight cleansing, improved detangling, and fiber reinforcement without silicones. For best results, incorporate the shampoo into the full Genesis system—conditioner and serum—to address scalp clarity, manageability, and strand strength together.
