L'oreal Vitamino Color Spectrum Professional Glass Shine Serum (1.01 oz) Heat Protection to 450°F | Color Protection & Anti-Frizz for 72 Hours

Experience high-performance shine and long-lasting color protection with the L'Oréal Vitamino Color Spectrum Professional Glass Shine Serum. This heat-activated leave-in formula is expertly designed for color-treated hair, helping you achieve a flawless glass-like finish that lasts up to 10 washes. Using advanced Alpha-Silane technology, the serum forms an ultra-thin protective layer that seals in moisture, boosts smoothness, and defends hair against heat, frizz, and humidity. It enhances all five dimensions of color vibrancy, shine, tone, saturation, contrast, and brightness, while resisting UV damage and environmental stress. Hair instantly appears more polished, silky, and vibrant with just one application.

Formulated to withstand temperatures up to 450°F (230°C), this professional-grade serum delivers salon-level protection against heat styling while locking in the day-one brilliance of your color. The lightweight texture distributes easily through damp hair, offering anti-frizz effects for up to 72 hours and powerful humidity resistance in up to 80% air moisture. After applying, simply blow dry and follow with a flat iron to activate the full resurfacing effect. The result is a smoother, more disciplined finish that’s touchably soft and visibly radiant—without weighing hair down or leaving behind any sticky residue.

Compact and potent, this 1.01 oz serum packs serious performance into every pump. Perfect for all hair textures, it helps you maintain your color-treated look between salon visits while controlling unwanted flyaways and dullness. For best results, use it after the full Vitamino Color Spectrum System—shampoo, conditioner, and mask—then style as desired. Its innovative formulation resists up to 10 shampoos, meaning your hair stays shinier, softer, and more manageable for longer. Whether you're styling for a sleek finish or simply aiming to extend your color's vibrancy, this serum is a must-have for any heat styling routine.
