6X more shine, pH 4.5 acidic technology, professional color-sealing treatment

Overview

Lock in your salon color with L'Oréal Professionnel Serie Expert Vitamino Color Concentrate. This professional acidic shine-sealing treatment is powered by pH 4.5 technology that neutralizes color's alkalinity and rebalances hair to its optimal pH level. Enriched with Resveratrol, a powerful polyphenol antioxidant from grape seeds, this innovative liquid-to-milk formula seals the cuticle and strengthens the hair fiber for optimal color protection. Clinically proven to deliver 6X more shine immediately after application, this 400ml professional backbar size is the perfect finishing treatment after any color service—leaving hair visibly shinier, softer, and with color locked in for up to 8 weeks.

What It Does

• Seals the cuticle — acidic pH 4.5 technology locks color molecules inside the hair fiber
• Delivers 6X more shine — instant luminosity immediately after application
• Strengthens hair fiber — 81% reduction in breakage for more resistant hair
• Rebalances pH — neutralizes alkalinity after coloring to restore optimal hair condition
• Transforms texture — liquid formula turns milky on wet hair for easy, even application

Key Technology & Ingredients

The Vitamino Color Concentrate harnesses L'Oréal Professionnel's advanced pH 4.5 acidic sealing technology. Unlike regular conditioners, this treatment works by resetting hair to its optimal acidic pH after the alkaline coloring process. At its core is Resveratrol, the same powerful polyphenol found in red wine, combined with Tartaric Acid for cuticle-sealing action and Niacinamide for fiber strengthening.

Who Is It For

• Freshly colored hair — ideal immediately after any color service
• Color-treated hair — permanent, semi-permanent, highlights, or balayage
• Salon professionals — as a finishing treatment after color services
• Dull colored hair — needing an instant shine boost
• Sensitized hair — weakened after technical services

How to Use

Application Steps

1. Shake well — ensure product is properly mixed before use
2. Apply after shampoo — on damp, towel-dried hair
3. Apply to lengths — distribute directly and evenly, avoiding roots
4. Emulsify — massage until the liquid transforms into a milky texture
5. Rinse immediately — no waiting time required, rinse thoroughly

Pro Tip: Use as a replacement for conditioner or mask directly after coloring services. For weekly maintenance, alternate with your regular Vitamino Color treatment to maintain the acidic seal and maximize color longevity.
