Schwarzkopf Professional OSiS+ Session Label Super Dry Fix is a strong-hold aerosol hairspray built for session and editorial styling, using a micro-diffuser nozzle that releases an ultra-fine, fast-drying mist rather than a heavy, wet spray.
The fine dispersion is designed to build strong, long-lasting hold without visible product buildup or a stiff, glued-down feel, and the finished style can still be brushed out for restyling. The formula relies on alcohol denat. and a film-forming acrylates copolymer to lock hair in place, along with added fragrance.
To use, hold the can roughly 25cm (10 inches) from dry, styled hair, spray briefly and evenly, and let it dry before touching or moving on to the next step. Because it's alcohol-based, frequent heavy use can be drying to hair over time, and the fragrance in the formula makes it unsuitable for fragrance-sensitive users.
