Goldwell StyleSign Strong Hairspray is a vegan, color-safe aerosol hairspray rated hold factor 4 out of 5 in Goldwell's StyleSign line, built to hold styles through up to 72 hours of humidity and frizz exposure. The formula is built around Bambusa Vulgaris (bamboo) shoot extract along with UV-protecting polymers, and dries with a lower-shine, more natural-looking finish (shine level 1 out of 3) rather than a glossy lacquer look. It suits all hair types and lengths, for both everyday styling and looks that need to hold through a long day or humid conditions. Spray onto dry, styled hair as a finishing step; it can also be brushed through once dry for a softer look.
