Extra Strong Hairspray is an aerosol finishing spray from Goldwell's StyleSign Hairspray range, built for maximum hold with a glossy, lacquer-like finish on all hair types. Formulated with Goldwell's Marine Bamboo complex, it sits at the top of the brand's hold scale and is designed to give styles up to 72 hours of resistance to humidity and frizz along with wind resistance. The fine mist locks styles in place without leaving hair stiff, sticky, or visibly flaked with residue. To use, complete your style, shake the can, hold it roughly 20–30 cm (8–12 inches) from hair, and mist evenly in short bursts; layer for extra hold and let it dry before touching.
