Goldwell’s Kerasilk Control Smoothing Fluid tames rebelliously frizzy, hard-to-control hair, transforming them into silky-smooth, cascading tresses full of shine and vitality. Offering thermal protection to intercept damage caused by heat-powered tools, the lightweight and milky formula preps tresses for styling. Exclusive KeraShape Technology harnesses a new generation of smoothing ingredients like Glyoxylic Acid, Keratin, and Silk Proteins to penetrate deep into the hair shaft, creating new keratin bonds that stabilise the hair shape for up to five months. Applied to the lengths and ends of damp, towel-dried hair, the leave-in protecting fluid smoothens the rough hair surface for brilliant shine and enviable suppleness.
