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

KÉRASTASE Genesis Hydra-Fortifiant Shampoo is a daily strengthening cleanser formulated to hydrate the scalp and reduce hair breakage from brushing for weak, oily, or combination hair.

This silicone-free bain from KÉRASTASE gently removes sebum, pollution and product build-up while nourishing fragile strands. Enriched with Ginger Root and Edelweiss native cells, the formula targets hair weakened by heat styling and mechanical stress without weighing hair down. It’s designed to be used regularly as the cleansing step in the Genesis routine to prep hair for conditioning and targeted serums.

How does this shampoo reduce hair fall caused by breakage?

The formula fortifies the hair fiber to make strands less prone to snapping during brushing and styling. It focuses on improving hair resilience rather than altering scalp oil levels excessively, so you get reinforcement where fragile fibers need it most.

• Contains Ginger Root and Edelweiss cells to strengthen the hair fiber.
• Gently cleanses to remove sebum and pollution that can cling to weakened roots.
• Silicone-free texture avoids coating hair, preserving lightness and manageability.

Will this work for oily or combination scalps without over-drying?

Yes — the Hydra-Fortifiant formula balances effective cleansing with hydration, stripping excess oil and buildup while maintaining scalp comfort. It’s suitable for normal, oily and combination hair types that need strengthening without heavy conditioners.

• Removes oil buildup and traces of pollution for a cleaner scalp feel.
• Hydrating actives prevent tightness that can follow harsher clarifying shampoos.
• Recommended follow-up: use a lightweight conditioner in the Genesis line to avoid weighing roots down.

How should I use it for best results in a daily routine?

Apply the shampoo to thoroughly wet hair, lather, rinse and repeat to ensure an even, gentle cleanse. Pairing with the matching Genesis conditioner and hair serum maximizes strengthening and detangling benefits for fragile or heat-stressed hair.

• Wet hair completely, apply a small amount, emulsify into a lather and rinse.
• Repeat if hair has heavy product or oil buildup for a deeper clean.
• Follow with a Genesis conditioner and finish with the collection’s serum for targeted reinforcement.

Is this safe for thin or fine hair types?

The lightweight, silicone-free composition is formulated to preserve volume while delivering nourishment, making it appropriate for thin or fine hair that becomes vulnerable to breakage. It strengthens fibers without coating them, helping hair retain natural movement and body.

• Silicone-free to avoid flattening fine strands.
• Designed to detangle and nourish without heavy residue.
• Suitable for use as part of a daily haircare routine for fine, fragile hair.

Who is this for: KÉRASTASE Genesis Hydra-Fortifiant Shampoo is intended for people with weak, damaged or heat-stressed hair—especially those with oily or combination scalps, or thin strands prone to breaking during brushing. If you want a daily shampoo that cleans thoroughly, hydrates the scalp, and reinforces fragile fibers without silicones or heavy buildup, this product is designed to be the cleansing step in a reinforcing regimen when used alongside the Genesis conditioner and serum.
