KÉRASTASE Nutritive Masquintense Riche Hair Mask 6.8 oz — Deep Nourishment for Medium‑Thick Hair

Kérastase Nutritive Masquintense Riche is an ultra-concentrated weekly hair mask that deeply nourishes, detangles, and strengthens very dry medium-to-thick hair.

This rich treatment is formulated to replenish moisture and restore softness without weighing hair down. It combines plant-based proteins and niacinamide to help hair retain hydration, increase manageability, and boost natural shine. Designed for use after shampooing, the masque is a leave-in for five minutes that targets mid-lengths and ends to address dryness and surface roughness.

How quickly will I notice softer, more manageable hair?

Visible softness and improved comb-through can appear after just one use because the formula is highly concentrated and designed to coat and smooth the hair fiber. Regular weekly use reinforces moisture retention and helps reduce tangles over time.

• One 5-minute treatment after cleansing for instant softness
• Concentrated texture delivers intensive nourishment per application
• Plant-based proteins support hair structure for easier detangling

What key ingredients deliver the benefits?

This mask combines plant-derived proteins with niacinamide to hydrate and support hair strength. The proteins supply essential nutrients to the fiber while niacinamide helps lock in moisture, resulting in longer-lasting softness and a smoother surface finish.

• Plant-based proteins: replenish and fortify hair fibers
• Niacinamide: aids moisture retention and surface repair
• Ultra-concentrated base: minimizes product use while maximizing effect

How should I use this masque for best results?

Apply to clean, wet hair focusing on mid-lengths and ends, massage evenly, leave for five minutes, then rinse thoroughly. For a complete routine, combine with a matching Nutritive shampoo, conditioner, and a heat-protectant styling cream, plus nighttime care if desired.

• Use once weekly as an intensive treatment
• Apply generously to mid-lengths and ends after shampooing
• Rinse after five minutes; follow with styling heat protectant

Will this mask make my hair feel heavy or greasy?

Formulated for medium to thick dry hair, the masque is rich but designed to absorb into the fiber rather than leave surface residue when used as directed. Because it is ultra-concentrated, only the recommended amount is needed to avoid over-conditioning.

• Specifically tailored for medium-to-thick textures prone to dryness
• Use sparingly at the roots to prevent buildup
• Rinse thoroughly after the five-minute treatment

Who is this for: Kérastase Nutritive Masquintense Riche is created for people with very dry, medium-to-thick hair who want an intensive weekly treatment to improve softness, manageability, and shine. It suits those looking for a salon-grade nourishing masque that pairs with a targeted Nutritive routine and complements heat-protective styling products. If your hair is fine or oily at the scalp, consider the lighter Masquintense formulation tailored to finer strands; for medium-to-thick textures seeking deep hydration and easier detangling, this Riche version is a focused solution.
