Sebastian Microweb Fiber is a wax-based texturizer that breaks down into fine, fiber-like strands for touchable, remoldable texture -- think of it as a light-hold styling tool for shape and movement rather than a strong-hold product. It's built on a wax base of paraffin and microcrystalline wax, combined with conditioning and film-forming agents that let you restyle hair throughout the day without it stiffening up.
Unlike products marketed around strength or heavy hold, Microweb Fiber's actual job is remoldable texture -- pull hair into a new shape, and it holds that shape until you reshape it again, on any length from short and choppy to longer styles needing definition. The key to using it well is applying it to dry, not damp, hair; used on wet hair, the fibers won't separate and define the way they're designed to.
