KÉRASTASE Genesis Hair Mask 6.8 fl oz — anti-breakage strengthening mask for weakened, damaged hair

KÉRASTASE Genesis Masque Reconstituant is a rich, fortifying hair mask designed to nourish, detangle and reinforce weakened or damaged hair to reduce breakage.

This intensive mask from the KÉRASTASE Genesis line targets hair weakened by mechanical stress and chemical processing. Formulated with Native Edelweiss Cells, Ginger, and Arginine, the mask delivers concentrated moisture and structural support to hair strands, leaving hair softer, easier to comb, and more resilient against breakage caused by brushing and environmental factors.

How does this mask repair and strengthen hair?

The formula focuses on reinforcing the hair fiber and improving resistance to breakage rather than altering hair structure. Active ingredients work to replenish moisture, smooth the cuticle, and support the fiber so strands are less prone to snapping when handled.

• Native Edelweiss Cells help protect and preserve fiber integrity.
• Ginger contributes antioxidant and fortifying properties.
• Arginine supports the hair’s internal resilience and vitality.
• Rich emollients deeply condition lengths and ends for smoother texture.

When should I use the Genesis hair mask in my routine?

Use the mask after cleansing with a compatible shampoo—KÉRASTASE recommends Bain Hydra-Fortifiant from the same range. Apply to towel-dried hair, leave in briefly, then rinse to achieve optimal nourishment without weighing hair down.

• Apply after shampooing on damp hair for best absorption.
• Leave on for about 5 minutes for a daily or weekly boost.
• Concentrate on mid-lengths and ends where damage is most visible.
• Rinse thoroughly to maintain natural movement and shine.

Will this mask help reduce hair fall from breakage?

This treatment is formulated to lower hair fall specifically caused by breakage — not hair loss from medical or hormonal causes. By improving fiber strength and detangling hair, it reduces mechanical shedding that happens during brushing and styling.

• Reinforces fragile strands to resist snapping during styling.
• Detangling effect minimizes tugging and breakage when combing.
• Regular use alongside Genesis shampoo and conditioner supports cumulative protection.

How will this mask feel and perform on different hair types?

The texture is a rich, creamy mask that spreads smoothly and rinses clean, delivering softness without excessive residue. It suits weakened, chemically treated, or frequently styled hair; finer hair may prefer shorter contact time to avoid heaviness.

• Thicker, damaged hair: intenser moisturizing and improved manageability.
• Fine, weakened hair: use sparingly on lengths and ends to prevent weighing down.
• Color-treated hair: safe for added nourishment and protection of dyed strands.
• Curly or textured hair: enhances detangling and definition when combined with proper leave-in care.

Who is this for: KÉRASTASE Genesis Masque Reconstituant is ideal for anyone with weakened or damaged hair seeking a professional-strength mask that nourishes, detangles and reinforces strands to minimize breakage from brushing and styling. Use it as part of the Genesis regimen for cumulative improvement in softness, manageability, and fiber resistance.
