Kérastase Résistance Sérum Extentioniste, 50 ml

Sérum Extentioniste is an energizing leave-in treatment that targets the hair follicle to stimulate growth and reinforce the hair fiber from the root. Part of the iconic Résistance line, this serum is a critical step for those looking to achieve long, healthy hair. Infused with Ceramides and a specialized Nutrient Complex, it creates a protective barrier on the scalp while providing the essential "building blocks" for hair strength. With consistent use, it minimizes breakage at the source, allowing your hair to grow longer, stronger, and more vibrant.

Features

• Ceramides: Acts as a "cellular cement," filling in the gaps in the hair cuticle to restore surface integrity and provide immediate smoothness.
• Creatine R Complex: A powerful combination of Creatine (an amino acid) and Ceramides that reinforces the internal structure of the hair fiber.
• Scaling Technology: Protects the scalp from environmental stressors and oxidative damage, ensuring an optimal growth environment.
• Lightweight Fluid: A non-greasy, water-like consistency that absorbs instantly into the scalp without leaving any residue or weighing down the roots.

Benefits

• Root Strengthening: Significantly improves the resistance of the hair fiber from the very first centimeter of growth.
• Accelerated Length: By reducing breakage at the root and mid-lengths, it helps you reach your "dream length" faster.
• Scalp Vitality: Refreshes and energizes the scalp, promoting better microcirculation to nourish the follicles.
• Visible Shine: Smooths the hair near the scalp, giving the entire mane a healthier, more polished appearance.

Package Contents: 50 ml (1.7 oz) luxury glass bottle with a precision pipette.

Recommended Usage

• Application: Use 1-2 times per week on a clean, towel-dried scalp.
• Technique: Using the pipette, apply 2-3 full droppers directly to the scalp in sections (front, sides, and crown).
• Massage: Use your fingertips to massage the serum in circular motions to ensure even distribution and to stimulate the scalp. Do not rinse.
• Pro Tip: For the ultimate "Long Hair Program," use this serum in combination with the Bain Extentioniste shampoo and Fondant Extentioniste conditioner. This 3-step system is clinically proven to reduce breakage by up to 99%.
