L'Oréal Professionnel Vitamino Color Spectrum Conditioner - 500ml

L'Oréal Professionnel Serie Expert Vitamino Color Spectrum — conditioner for colour protection and radiance of dyed hair

Vitamino Color Spectrum Conditioner is an updated version of the classic Vitamino Color, developed with a fundamentally different approach to colour protection. While the classic line relies on antioxidant pigment protection through resveratrol, Spectrum uses an acid system of ferulic and glycolic acids that acts directly on the keratin bonds of the hair structure. The concept is to preserve all five dimensions of colour simultaneously: shine, saturation, contrast, hue and vibrancy. According to clinical data, the conditioner paired with the shampoo provides up to 100 days of first-day colour retention, strengthens hair by 98% compared to a non-conditioning shampoo, and delivers 45% more smoothness and 41% more softness within a complete routine system.

Key features and benefits

• Ferulic Acid — the key active ingredient that sets Spectrum apart from the classic Vitamino Color. A natural phenolic antioxidant derived from plant cell walls. In the context of colour protection, ferulic acid serves a dual function: it neutralises free radicals that destroy synthetic pigment molecules under UV and thermal stress, and it reinforces the hair's own keratin bonds, reducing cuticle porosity. Ferulic acid is a significantly more potent antioxidant than the resveratrol in the classic line and works synergistically to enhance the effects of vitamins C and E.
• Glycolic Acid — an AHA with the lowest molecular weight among alpha-hydroxy acids, allowing it to penetrate directly into the hair cortex. It reinforces the network of hydrogen and ionic bonds in keratin, strengthening the fibre structure from within. Additionally, it regulates the formula's pH, closing the cuticle scales and neutralising unwanted warm tones — this is the mechanism behind the conditioner's claimed "neutralising effect".
• Citric Acid 2.5% — in Spectrum, citric acid is present at a significant concentration of 2.5% (ranking third in the INCI list), which fundamentally distinguishes it from its role as a trace-level pH regulator. At this concentration, citric acid actively seals the cuticle scales, enhances colour vibrancy and saturation, and neutralises unwanted yellow and brassy tones commonly seen in fading colour.
• Aminopropyl Dimethicone + Bis(C13-15 Alkoxy) PG-Amodimethicone — a specialised silicone duo with a high smoothing profile. Aminopropyl Dimethicone selectively deposits on damaged areas, while Bis(C13-15 Alkoxy) PG-Amodimethicone creates a mirror-like coating across the entire cuticle surface. This combination is what delivers the 45% increase in smoothness and Spectrum's signature glass-like shine.
• Butyrospermum Parkii Butter (Shea Butter) — a nourishing ingredient absent from the classic Vitamino Color conditioner. It restores the intercellular lipid layer of the cuticle, reduces moisture loss from the cortex, and leaves hair soft and elastic. Particularly important for bleached hair with high porosity.
• Glycine — the simplest amino acid and a building block of keratin. It strengthens the hair's protein matrix from the outside, working in synergy with the formula's acid system.
• Hydroxypropyl Guar + Polyquaternium-37 + Acrylates/Stearyl Methacrylate Copolymer — a three-component polymer complex that provides anti-static effect, smoothness and humidity protection. The acrylate copolymer forms a stable matrix on the hair surface that locks in colour shape when exposed to humid air.

Who the product is for

The conditioner is designed for all types of coloured, highlighted and bleached hair that need not just antioxidant protection but also active colour correction — neutralising unwanted undertones and enhancing saturation and shine between colour services. Particularly suitable for cool tones (ash, platinum, pearl), which tend to warm up as they wash out. Suitable for all hair textures from fine to thick. For heavily damaged bleached hair, it is recommended to complement with the Vitamino Color Spectrum Mask for more intensive nourishment.

Directions for use

After washing with Vitamino Color Spectrum Shampoo, divide hair into four sections and apply the conditioner evenly from mid-lengths to ends. Gently massage for 1–2 minutes for better penetration. Leave on for 2–3 minutes and rinse thoroughly. For maximum results, use as part of the complete Vitamino Color Spectrum routine with the neutralizing shampoo and Glass Shine Serum as a finishing serum.
