Directions
STEP 1 of the Uberliss Keratin Smoothing Treatment: Before applying the product, shampoo the hair with Überliss Hydrating Shampoo. After shampooing, rinse well and towel blot. Divide the hair into sections. Gently shake the Überliss Fiber Expander and spray onto wet hair (20-25 strokes). Do not oversaturate hair. Using hand dryer, dry the hair approximately 80%. Follow with STEP 2 Uberliss Fiber Restructure.
What is a keratin treatment?
The 2-step Uberliss Keratin Treatment (Fiber Expander and Fiber Restructure) is a formaldehyde free smoothing treatment for clients who want softer, smoother hair for 3-4 months. Frizzy hair types may see the most dramatic results. Clients with curls and coils wishing to retain their hair pattern can still use the treatment. While the treatment is engineered for volume and curl reduction, stylists can dial down the heat of the flat iron and do fewer passes to retain more of the clients' curls. *The Smoothing Treatment is perfectly compatible with other smoothing treatments, color services, and chemical processes. For professional use only.
How long does keratin treatment last?
3-4 months.
How does it work?
The Fiber Expander prepares the hair by balancing the pH level and expanding the cuticle, which allows the 2nd Step to penetrate deeply and form an ultra conditioning mesh. It’s formulated for peak hydration, unlike typical clarifying shampoos often used as first steps in other smoothing treatments.
How is it different from hair botox or nanoplastia?
The Uberliss Smoothing Keratin Treatment is a formaldehyde-free system that smooths frizz while preserving the hair’s natural texture, making it gentler and more versatile than nanoplastia, which chemically restructures the hair for a pin-straight look. Unlike hair botox, which primarily works as a deep-conditioning filler for damaged strands, Uberliss focuses on long-lasting frizz control and manageability without heavy buildup.
