Nail Shield TREATMENT FOR SHORT NAILS strengthens and protects brittle nails. How to use: 1) Apply a layer of nylon fibers to the entire surface of the nail. Let it dry until you feel the nylon fibers stretch across the nail and form a network that strengthens it. The nail is slightly rough. 2) Apply a coat of leveler and let it dry completely. If you notice that the surface of the nail is still rough, apply another coat and let it dry completely. Now the surface of the nail is smooth and you can continue with your manicure. Features: It consists of two phases that, by completely protecting the nail from all aggressions and impacts, allow it to rebuild and regenerate. Phase 1 Nylon Fibers: a strengthening formula to which nylon fibers have been added that distribute themselves in a uniform weave across the surface of the nail to strengthen it as effectively as if it were a second nail. Second-phase leveler: The role of the leveler is to smooth the surface of the nail by gently removing the roughness of the previously used nylon fibers. Code M90803
