Keep rebellious frizz & unruly flyways in check with the Goldwell Kerasilk Control Shampoo; a smoothing & controlling shampoo that gently cleanses whilst taming unmanageable tresses, offering structural support & preserving colour vibrancy. Effectively removing impurities & excess oils, the daily shampoo is developed with exclusive Kerashape Technology, which harnesses a new generation of smoothing ingredients like Glyoxylic Acid, Keratin, & Silk Proteins to penetrate deep into the hair shaft, creating new keratin bonds that stabilise the hair shape for up to five months. Wave goodbye to dry, brittle & wiry locks, & hello to an enviably soft & silky-smooth mane.
