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

KÉRASTASE Genesis Masque Reconstituant is a rich strengthening hair mask that intensely nourishes, detangles, and reinforces weakened or damaged lengths to reduce breakage risk.

Designed for hair that has been weakened by mechanical stress or repeated styling, this treatment replenishes moisture and rebuilds fiber resistance without weighing hair down. Formulated with Native Edelweiss Cells, Ginger extract and Arginine, the mask targets fragile areas to deliver softness, improved manageability and a healthier-looking finish when used after cleansing with the Genesis Bain Hydra-Fortifiant shampoo.

How does this mask make fragile hair stronger?

The formula works by infusing moisture into the hair fiber and providing structural support so strands are less likely to snap during brushing or styling. Key actives work together: Edelweiss-derived ingredients help protect, ginger supports resilience, and arginine contributes to fiber fortification.

• Reinforces hair fiber to reduce breakage during mechanical stress
• Restores softness for smoother detangling and less pulling
• Moisture balance improves elasticity and flexibility of the strand

When and how should I use this mask for best results?

Use the mask after shampooing with Bain Hydra-Fortifiant: apply a small amount through lengths and ends, massage gently, leave for about five minutes, then rinse thoroughly. For optimal reduction in hair fall due to breakage, incorporate it into your routine 1–2 times weekly or as needed depending on damage level.

• Apply to towel-dried hair after Genesis shampoo
• Concentrate on mid-lengths and ends where breakage is most visible
• Leave on for 5 minutes before rinsing for full absorption

Will this mask weigh down fine hair or leave residue?

The masque is formulated to deliver deep nourishment while keeping hair feeling light and conditioned rather than heavy. Because you use only a small amount and rinse well, fine hair typically benefits from added softness without excess buildup when used sparingly.

• Light rinsable texture minimizes residue when applied correctly
• Small quantities are effective for fine hair—avoid over-application
• Pair with Genesis Bain Hydra-Fortifiant for balanced results

What ingredients are responsible for the strengthening effect?

KÉRASTASE combines plant-derived Edelweiss cells, ginger extract and the amino acid arginine to support fiber integrity and hydration. These components work synergistically to restore manageability and help hair resist breakage from everyday handling and styling.

• Native Edelweiss Cells: protective and restoring benefits
• Ginger extract: supports fiber resistance and vigor
• Arginine: an amino acid that helps reinforce weakened strands

Who is this for: KÉRASTASE Genesis Masque Reconstituant is suited for people with weakened, processed or frequently styled hair who want to reduce breakage and improve softness. It’s recommended for anyone seeking a targeted strengthening treatment—especially those already using the Genesis Bain Hydra-Fortifiant shampoo and Fondant Renforcateur conditioner for a complete reinforcement routine.
