KÉRASTASE Nutritive Masquintense Mask for Fine to Medium Dry Hair — 6.8 fl oz, Deep Nourishing Lightweight Treatment

KÉRASTASE Nutritive Masquintense is a concentrated weekly hair mask that deeply nourishes and detangles fine to medium dry hair with plant-based proteins and niacinamide.

This rich treatment is designed to replenish moisture, improve manageability, and leave hair feeling softer and looking shinier without weighing down finer strands. Formulated with plant-derived proteins to feed the fiber and niacinamide to help retain hydration, the 6.8 fl oz Masquintense Mask is part of the Nutritive lineup aimed at restoring dry, dehydrated hair through concentrated nourishment and slip for easier styling.

How does this mask improve moisture and manageability?

The mask delivers concentrated conditioning agents that soak into the hair fiber to restore suppleness and reduce tangles. Its texture provides immediate slip, making comb-through during rinsing easier and minimizing breakage from wet brushing.

• Plant-based proteins rebuild and replenish hair surface nutrients.
• Niacinamide helps lock in moisture for longer-lasting hydration.
• Rich, yet balanced consistency detangles without heavy residue.
• Use weekly for cumulative improvement in softness and shine.

Will this work for fine hair without flattening volume?

Yes — the Masquintense formula for fine to medium dry hair is concentrated but lightweight enough to nourish without leaving hair limp. Applied mainly to mid-lengths and ends, it targets the driest areas and avoids buildup at the roots, helping retain natural body and movement.

• Apply sparingly near roots; focus on mid-lengths and ends.
• Short five-minute leave-in time reduces risk of weighing hair down.
• Rinse thoroughly to preserve volume and natural texture.
• Pair with Nutritive shampoo and conditioner for balanced care.

How do I use it for best results in my routine?

Use the mask as a weekly intensive treatment after shampooing. Apply a generous amount to clean, wet hair, massage through mid-lengths and ends, leave for five minutes, then rinse; follow with heat protectant before styling for protection and shine.

• Step 1: Cleanse with a suitable Nutritive shampoo.
• Step 2: Apply mask to towel-dried mid-lengths and ends.
• Step 3: Leave for five minutes, then rinse thoroughly.
• Step 4: Finish with heat protectant or styling products if using heat.

What ingredients support its nourishing action?

The mask combines plant-based proteins that supply essential nutrients to the hair fiber with niacinamide to help the strand retain moisture. This pairing improves texture, reduces dryness, and enhances shine without relying on heavy oils that can weigh down finer hair types.

• Plant-based proteins provide targeted nourishment and structure support.
• Niacinamide (vitamin B3) helps maintain hydration within the hair.
• Concentrated cream texture maximizes conditioning with minimal product.
• Free-rinse formula designed for weekly intensive use.

Who this is for: KÉRASTASE Nutritive Masquintense Mask in the fine-to-medium formula is ideal for people with very dry but fine to medium-thick hair who need a powerful weekly boost of moisture and detangling without sacrificing volume. Choose this if your lengths feel brittle, styling takes extra effort due to knots, or your hair lacks radiance — incorporate it into a Nutritive routine for best cumulative effects.
