L’Oréal Professionnel Serie Expert Vitamino Color Spectrum Glass Shine Serum
Available Size: 50ml
L’Oréal Professionnel Serie Expert Vitamino Color Spectrum Glass Shine Serum is a professional leave-in finishing serum designed to deliver an ultra-glossy, glass-like shine whilst helping to preserve the vibrancy of colour-treated hair. Going beyond a traditional serum, this innovative formula coats the hair cuticle with a protective layer that locks in shine for up to 72 hours whilst protecting against humidity, frizz and heat styling.
Enriched with 5% Alpha-Silane, an advanced heat-activated care ingredient, the serum forms a protective film over the hair fibre when activated with heat. The result is exceptionally smooth, luminous hair with enhanced colour brilliance and long-lasting protection.
Advanced Glass Shine Technology
The Vitamino Color Spectrum range has been developed to maximise colour vibrancy whilst delivering exceptional shine. Powered by 5% Alpha-Silane Technology, the Glass Shine Serum creates a durable protective coating around the hair fibre when activated by heat, helping maintain a sleek finish, minimise frizz and preserve salon-fresh colour.
