KÉRASTASE Nutritive Masquintense Riche Hair Mask for Medium-to-Thick Dry Hair, 6.8 fl oz — Deep Nourish & Detangle

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

This rich treatment is formulated for hair that needs intensive moisture, improved manageability, and a luminous finish. Designed as a weekly ritual, Masquintense Riche replenishes strands from the mid-lengths to ends, smoothing rough texture and making styling easier. Its thick, enveloping texture clings to hair to deliver concentrated nourishment where dryness is most pronounced.

How does this mask improve very dry, medium-to-thick hair?

The formula supplies targeted hydration and reinforcing nutrients to help hair feel softer and look shinier. It focuses on the areas that suffer the most—mid-lengths and ends—restoring suppleness without weighing thicker hair down when used as directed.

• Plant-based proteins replenish essential building blocks in the fiber.
• Niacinamide helps retain moisture for longer-lasting softness.
• Ultra-concentrated texture ensures a deep, visible smoothing effect in one treatment.

When and how should I use Masquintense Riche for best results?

Use this mask as a weekly, in-shower treatment after cleansing. Apply generously to clean, wet hair, focusing on mid-lengths and ends, leave for five minutes, then rinse; follow with a heat protectant for styling.

• Apply after shampooing to towel-dried, wet hair.
• Massage through mid-lengths and ends; do not overload the roots.
• Leave on for five minutes for an intensive result, then rinse thoroughly.

Will this weigh down thick hair or affect styling?

Masquintense Riche is formulated specifically for medium-to-thick textures, so it provides concentrated nourishment without leaving hair limp when used correctly. Rinsing well and following with a lightweight heat protectant keeps movement and body while improving manageability.

• Designed for medium-to-thick hair density to avoid excess residue.
• Leaves hair easier to detangle and style, reducing breakage during combing.
• Works best as part of a routine with Nutritive shampoo and conditioner.

What key ingredients are responsible for the benefits?

The mask blends plant-based proteins and niacinamide to nourish, strengthen and help lock in hydration. Together these act to improve softness, shine and the hair’s resistance to everyday stressors like brushing and heat styling.

• Plant-based proteins: rebuild and nourish the fiber's structure.
• Niacinamide: supports sustained moisture retention and smoothness.
• Ultra-concentrated emollients: provide instant detangling and a radiant finish.

Who is this for: KÉRASTASE Nutritive Masquintense Riche is ideal for people with medium-to-thick hair that feels very dry, rough, or hard to detangle. Choose this mask if you want a once-a-week intensive treatment to restore softness, add shine, and make styling simpler—especially when used alongside other Nutritive collection products for a complete care routine.
