Uberliss Step One Fiber Expander 16 Oz

The Uberliss Fiber Expander is a revolutionary pre-treatment exclusively developed by Uberliss and serves as the essential first step in the brand's two-step keratin smoothing system. It delivers dual functionality: conditioning the hair cortex while simultaneously expanding the cuticles using a crosslinking Di-Amine agent — a mechanism no other brand's pre-treatment replicates. The Fiber Expander prepares the hair by balancing the pH level and expanding the cuticle, which allows the second step to penetrate deeply and form an ultra-conditioning mesh. It is formulated for peak hydration, unlike typical clarifying shampoos often used as first steps in other smoothing treatments. Infused with Aloe Vera, it provides extra protection for both hair and scalp, while Avocado Oil delivers deep nourishment throughout the strand. The complete two-step Uberliss Keratin Treatment is a formaldehyde-free smoothing system designed for clients who want softer, smoother hair for 3 to 4 months — with frizzy hair types seeing the most dramatic results, and clients with curls and coils able to retain their natural pattern. The formula also offers added color protection and is for everyday use only, dispensed in a generous 16 oz / 475 ml bottle. How to Use Begin by shampooing hair with Uberliss Hydrating Shampoo, rinsing well, and towel blotting before dividing the hair into sections. Gently shake the Fiber Expander and spray evenly onto wet hair using 20–25 strokes, taking care not to oversaturate. Using a hand dryer, dry the hair approximately 80%, then proceed immediately to Fiber Restructure Step 2 to complete the smoothing system.
