Keep rebellious frizz and unruly flyways in check with the Goldwell Kerasilk Control Shampoo; a smoothing and controlling shampoo that gently cleanses whilst taming unmanageable tresses, offering structural support and preserving colour vibrancy. Effectively removing impurities and excess oils, the daily shampoo is developed with exclusive Kerashape Technology, which 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. Wave goodbye to dry, brittle and wiry locks, and hello to an enviably soft and silky-smooth mane.
