L'Oreal Professionnel Serie Expert Vitamino Colour Spectrum Glass Shine Hair Serum (50ml) is an advanced colour-protecting serum designed to coat the hair cuticle, delivering ultimate colour protection and long-lasting, glass-like shine.

Infused with 5% Alpha-Silane, this high-performance formula creates a protective layer on the hair fibre when activated by heat, locking in vibrancy while shielding against environmental stressors. The result is sleek, polished hair with up to 72 hours of shine, enhanced resistance to humidity, and protection against frizz. Offering heat protection up to 230°C, this serum is ideal for use with a straightening iron to achieve a flawless, ultra-glossy finish. Please note that this product is designed specifically for use with a straightening iron.
