Protect your ‘do from hair-flattening and frizz-inducing humidity with Goldwell’s Kerasilk Control Humidity Barrier Spray. A weightless spray that forms a defensive shield against environmental moisture to keep unsightly frizziness at bay. Exclusive KeraShape Technology works to smooth out haywire locks, harnessing the smoothing effects of 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. Unruly, hard-to-manage hair is transformed into a super-sleek, satin-soft and polished mane.
