KÉRASTASE Genesis Strengthening Hair Mask — Anti-Breakage Nourishing Masque, 6.8 fl oz

If your hair looks fragile from styling, brushing or environmental stress, KÉRASTASE Genesis Masque Reconstituant is formulated to restore moisture, resilience and slip. This creamy treatment targets weakened lengths and ends with a blend of strengthening actives to help improve hair fiber integrity while making detangling easier. Use after cleansing to deliver concentrated nourishment without weighing hair down.

How quickly will I notice less breakage?

Visible benefits vary with hair condition and routine, but many users report easier detangling and fewer snapped strands after several uses. The mask works over repeated applications to reinforce fibers and reduce mechanical breakage from brushing and heat styling.

• Apply after shampooing for immediate slip and smoother comb-through.
• Leave on for about five minutes for concentrated replenishment.
• Continued use with the Genesis shampoo and conditioner improves overall resistance.

What key ingredients help strengthen hair?

The formula combines plant-derived Native Edelweiss Cells with ginger extract and arginine to support fiber strength and scalp activity linked to hair resilience. These ingredients aim to fortify weakened strands and make hair less prone to breakage from daily handling.

• Native Edelweiss Cells: support fiber protection against external aggressors.
• Ginger extract: adds fortifying properties and nourishment.
• Arginine: an amino acid that helps reinforce structure within the hair fiber.

How should I use this mask for best results?

For optimum performance, pair the masque with Genesis Bain Hydra-Fortifiant shampoo and Fondant Renforcateur conditioner. Apply a small amount through lengths and ends after washing, massage to distribute, leave on for five minutes and rinse thoroughly.

• Start with clean, towel-dried hair for even absorption.
• Concentrate product on mid-lengths and ends where damage is concentrated.
• Use once or twice weekly, more often for very dry or chemically treated hair.

Will this mask weigh down fine hair?

The masque is designed to deliver rich nourishment while maintaining lightness when used in appropriate amounts. Fine hair typically benefits from a small, targeted application to avoid buildup, focusing on lengths and ends rather than roots.

• Use a pea-sized to dime-sized amount for fine hair, increasing as needed.
• Avoid scalp application to prevent heaviness or greasiness.
• Rinse thoroughly to preserve natural movement and volume.

Who is this for: KÉRASTASE Genesis Masque Reconstituant is ideal for people with weakened, processed or frequently styled hair that needs concentrated moisture, improved manageability and reinforcement against breakage. It suits those looking to reduce hair loss caused by breakage rather than hereditary shedding, and it works well within a routine that includes the matching Genesis shampoo and conditioner for best results.
