KÉRASTASE Nutritive Masquintense Riche Hair Mask, 6.8 fl oz — Deep Nourish for Medium‑Thick Hair

KÉRASTASE Nutritive Masquintense Riche is an ultra-concentrated weekly hair mask that deeply nourishes and detangles very dry, medium-to-thick hair using plant-based proteins and niacinamide.

This intensely hydrating mask is formulated to restore softness, manageability, and noticeable shine to hair that feels dry or rough. Designed as a weekly treatment, Masquintense Riche delivers concentrated nutrition from mid-lengths to ends, smoothing the hair fiber while helping it retain moisture. The rich texture spreads easily and rinses clean, leaving hair easier to style and more resilient against everyday mechanical stress.

How will this mask improve the feel and appearance of my dry, medium-to-thick hair?

The formula combines plant-based proteins to replenish the fiber with niacinamide to support moisture retention, resulting in hair that feels softer and looks glossier. With a deeply conditioning action, the mask reduces roughness and enhances detangling, so wet hair is easier to comb and dry hair appears smoother.

• Restores softness and silkiness from mid-lengths to ends.
• Reduces frizz and surface roughness for improved shine.
• Helps hair feel stronger and less prone to tangling.

When and how should I use Masquintense Riche in my routine?

Use this treatment once a week after shampooing, on clean, wet hair for best results. Apply a generous amount through mid-lengths and ends, leave in for five minutes, then rinse; follow with a heat-protectant for styling if needed.

• Weekly application as an intensive care step.
• Massage through wet hair, leave five minutes, then rinse thoroughly.
• Pair with Nutritive shampoo, conditioner, and a heat protectant for optimal results.

What benefits do the key ingredients provide without making hair heavy?

Plant-based proteins replenish and nourish the hair fiber while niacinamide helps lock in hydration, balancing nourishment without leaving a greasy residue. The ultra-concentrated texture is crafted for medium-to-thick hair, delivering richness where needed while allowing the hair to retain natural movement and bounce.

• Plant-based proteins: rebuild and nourish the fiber internally.
• Niacinamide: supports long-lasting hydration and surface smoothness.
• Concentrated formula: targeted nutrition without weighing hair down when used as directed.

How quickly will I notice results and how long do they last?

Many users notice improved softness, easier detangling, and increased shine after the first treatment. With consistent weekly use and complementary Nutritive products, the cumulative effect helps maintain hydration and manageability between treatments.

• Immediate improvements in texture and combability after one use.
• Progressively stronger-looking hair with ongoing weekly treatments.
• Best maintained by combining with Nutritive shampoo, conditioner, and heat protection.

Who is this for: KÉRASTASE Nutritive Masquintense Riche is created for people with medium-to-thick hair that tends to be very dry, coarse, or hard to detangle. If you want a concentrated, weekly nourishing mask that restores softness, enhances shine, and improves manageability without sacrificing movement, this treatment is made to be part of your care routine. Not intended for daily use — apply as an intensive weekly step and continue regular cleansing and protective styling for long-term improvement.
