Shaper Zero Gravity is an ultralight-hold aerosol hairspray from Sebastian Professional, made for fine-to-medium hair that needs light, brushable control rather than a firm, set hold.
The formula uses alcohol denat. as its base with lightweight film-forming polymers, so hair stays movable and can be brushed through or restyled during the day without going stiff or crunchy. It's meant to be sprayed on before or after blow-drying or hot-tool styling, and re-sprayed as needed for extra hold without adding weight. Because the hold is light, it isn't intended for styles that need strong, long-lasting structure.
