Ultimate Smooth Glass Liquid - 6.2 oz

Achieve the viral "glass hair" aesthetic with the Wella Ultimate Smooth Glass Liquid Layer, a professional-grade leave-in treatment that delivers mirror-like gloss and unparalleled silkiness. This ultra-lightweight liquid transforms dry, unruly, or frizz-prone hair into a high-shine masterpiece in just 30 seconds. Unlike traditional heavy serums, this formula uses a micro-mist application to seal the hair cuticle with a weightless, light-reflective barrier that eliminates static and flyaways without the slightest hint of greasy buildup.

The secret behind its transformative power lies in Wella’s patented skincare-inspired technology, which fuses sugarcane-derived Squalane with nourishing Omega-9. Squalane mimics the hair's natural oils to provide deep internal emollience, while Omega-9 creates a durable, protective film on the hair's surface to recreate the lipid barrier. This duo provides intensive frizz control and humidity resistance that lasts up to 72 hours—staying effective even through your next shampoo—making it the ultimate "weather-proof" solution for humid climates or rainy days.

Designed for both salon professional use and high-end home maintenance, this liquid layer is a master of versatility; it can be applied to damp hair before blow-drying for a sleek foundation or used on dry hair as a final glossing step. It provides essential heat and UV protection, ensuring your hair stays strong and vibrant while you style. Dermatologically tested, vegan-friendly, and color-safe, it leaves hair up to 85% smoother and noticeably more manageable from root to tip. It’s a sensory experience that begins with a sophisticated "floriental" aroma and ends with hair that is so soft and luminous it truly mimics the appearance of liquid glass.

72-Hour Glass Finish: This leave-in spray creates a high-definition, light-reflective surface that lasts for up to 3 days, even after your next wash. It provides a long-lasting, salon-fresh appearance that maintains its mirror-like gloss through varying weather conditions.

Advanced Squalane & Omega-9: Utilizing patented skincare-inspired technology, the formula deeply nourishes hair from the inside while reinforcing the exterior lipid barrier. This unique combination transforms dull, parched strands into silky-soft, healthy-looking hair in just 30 seconds.

96-Hour Frizz & Humidity Defense: Engineered to resist humidity, the liquid layer provides up to 96 hours of anti-frizz protection, keeping your style sleek and disciplined. It acts as an invisible shield against moisture in the air, preventing unwanted volume and texture shifts.

Molecular Heat & UV Shield: The lightweight liquid coats each strand to provide essential protection against heat-styling tools and color-fading UV rays. It significantly improves detangling and combability, reducing mechanical breakage during the styling process.

Weightless Vegan Formula: The ultra-fine micro-mist is free from animal-derived ingredients and leaves no sticky or heavy residue, making it ideal for all hair types. It delivers an instant 85% increase in smoothness and softness without sacrificing the hair's natural bounce and movement.
