Garnier Fructis Keratin Sleek Heat-activated Serum - Dry And Frizzy Hair 50ml

Seal dry, frizz-prone cuticles and lock in sustained gloss with Garnier Fructis Keratin Sleek Heat-Activated Serum, a leave-in formula that bonds instantly when warmed by blow-dryers or flat irons. As the fourth and final stage of the Keratin Sleek routine, apply a measured pump to towel-dried hair before styling. Thermal activation triggers the keratin complex to penetrate damaged shafts, forming a flexible humidity-resistant barrier that stops static and retains light reflection.

Thermal Defense & Wash-Resistant Longevity

This serum guards against structural heat damage up to 230°C, allowing daily styling without increasing brittleness or split ends. Humidity resistance keeps textures flat and defined even in high-moisture environments. Instrumental testing confirms up to ten days of controlled smoothness, maintaining its sealing properties through five full shampoo cycles without requiring reapplication.

Optimal Application & Compatibility

• Mix a pea-sized amount into palms, emulsify, and distribute evenly from mid-lengths to ends before applying heat
• Pair with the first three Keratin Sleek steps (shampoo, conditioner, treatment mask) for cumulative smoothing effects
• Suitable as a standalone finishing polish for travelers or casual stylists who prefer a streamlined routine

The 50ml dosage vessel provides controlled dispensing for medium to long hair applications, ensuring each session uses only the product needed to avoid buildup while preserving maximum heat protection performance.
