Perfectly smooth and shiny hair is no longer just a runway look it’s now a reality within everyone’s reach.
Wella Professionals, the global leader in professional haircare, introduces Ultimate Smooth Glass Liquid Layer, a leave-in spray that instantly transforms dry, dull, and unruly hair, giving it long-lasting smoothness and a spectacular “glass hair” shine.

Smoothness and shine in just 30 seconds
Part of the new Ultimate Smooth range, this revolutionary product provides deep nourishment and visible smoothness from the very first use.
In just 30 seconds, hair becomes softer, more manageable, and noticeably shinier.
The professional formula delivers up to 96 hours of frizz control, keeping hair smooth for up to three days*, even in high humidity conditions.
Skincare-inspired technology: Squalane & Omega-9
Inspired by skincare innovations, Wella Professionals has introduced for the first time a patented technology that combines Squalane a sugarcane-derived ingredient known for its emollient properties with Omega-9 for intense hydration and lasting smoothness.
This unique combination nourishes the hair from within, strengthening it while recreating on the outside a protective barrier that reflects light, resulting in that spectacular “glass-like” effect.
“The Miracle Oil serum is extremely lightweight. You can apply multiple layers to achieve the most beautiful, glass-like shine you’ve ever seen,” says James Earnshaw, Global Ambassador for Wella Professionals.
