Wella Ultimate Smooth Glass Liquid Layer

Ultimate Smooth Glass Liquid Layer is a lightweight leave-in spray that delivers instant nourishment and long-lasting smoothness for sleek, frizz-free hair. Designed to work in just 30 seconds, it provides up to three days of frizz control and humidity protection—even lasting through the next wash. Formulated with Squalane and Omega-9, it deeply nourishes the hair from within while helping to replenish and smooth the outer layer for a glossy, “glass hair” finish. Suitable for color-treated hair, this dermatologically tested formula is free from animal-derived ingredients and helps transform dull, frizzy strands into soft, manageable, salon-smooth hair with lasting results.
