Protect your ‘do from hair-flattening & 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 Kera Shape Technology works to smooth out haywire locks, harnessing the smoothing effects of 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. Unruly, hard-to-manage hair is transformed into a super-sleek, satin-soft & polished mane.
