KÉRASTASE Genesis Masque Reconstituant Hair Mask 6.8 oz — Anti-Breakage, Strengthening Treatment for Weakened or Damaged Hair

KÉRASTASE Genesis Masque Reconstituant is an intensive strengthening hair mask that nourishes, detangles and reduces breakage for weakened or damaged hair.

This rich treatment is formulated to rebuild and reinforce fragile hair fibers after repeated mechanical stress and chemical processing. Enriched with Native Edelweiss Cells, Ginger extract and Arginine, the mask delivers moisture and structure to lengths and ends while improving combability and surface softness. Use it after cleansing with a complementary strengthening shampoo to restore resilience and a smoother finish.

How does this mask reduce hair breakage?

The formula targets the hair fiber to help restore cohesion and resistance while minimizing tangles that lead to breakage during brushing. Ingredients like Arginine support fiber health, while Edelweiss Cells and Ginger help fortify weakened areas of the strand.

• Reinforcing complex that strengthens lengths and ends
• Detangling agents lower mechanical stress from combing
• Moisture balance prevents dryness-related breakage

When and how should I use the Genesis Masque?

Apply after shampooing—ideally following the Bain Hydra-Fortifiant—to freshly washed, towel-dried hair. Work a small amount through mid-lengths to ends, leave on for about five minutes, then rinse thoroughly for best results.

• Use 1–2 times per week or as needed for weakened hair
• Apply mainly on lengths and ends, avoiding heavy roots
• Pair with Genesis Bain and Fondant Renforcateur for a full regimen

What immediate effects and longer-term benefits can I expect?

Right away you should notice improved softness, easier detangling and a more manageable texture. Continued use supports stronger-looking hair with reduced hair-fall due to breakage and enhanced resistance to daily stressors.

• Instant: smoother feel and easier combing
• Short term: reduced split ends and less snapping during styling
• Long term: reinforced fiber structure and improved resilience

Is this suitable for my hair type and concerns?

The mask is formulated for weakened, fragile or chemically processed hair that needs reinforcement and hydration. It is safe for most hair textures but is specifically designed to address breakage and combability problems rather than scalp conditions.

• Best for weakened, damaged or frequently styled hair
• Works on color-treated hair when used as part of a strengthening routine
• Not a scalp treatment; apply primarily to mid-lengths and ends

Who is this for: KÉRASTASE Genesis Masque Reconstituant suits anyone dealing with fragile, processed or frequently handled hair who wants an intensive conditioning treatment to improve softness, detangling and resistance to breakage. If your concern is hair-fall caused by breakage from brushing, styling or chemical services, this mask offers targeted nourishment and strengthening when used regularly as part of the Genesis routine.
