- The secret of style-sculpting. Remoldable fiber sculpter and hair putty. Fiber-fused for a matte texture. Mold, sculpt, and twist any uncombed-looking style for perfect second-day-look hair. Sculpt into damp or dry hair to mold the desired style. Blow with cold air to increase hair’s moist volume. Blow with hot air for moist, head-hugging shapes. Spread through dry hair for shiny separations. Best for thicker and layered hair. In the late ‘80s, walking through the streets of London, Sebastian was inspired by a non-conforming youth generation who wore their hair dirty and matted. To capture this look, Sebastian introduced a new, rich, creamy mud, infused with millions of hair-like fibers, further popularizing the grungy look. Molding Mud is the tool of the times—for rock stars and rebels.
