Reinforce soft, fragile nails whilst adding elasticity and support with Mavala Nail Shield. This two-phase nail strengthener builds up weak nails giving them resistance and preventing them from breaking. Directions for use: Phase I: Apply a coat of Nylon Fibre Base over the entire nail and allow it to dry. This forms a trellis over the nail. The nail will be slightly rough. Phase II: Apply a coat of Sealer and let it dry completely. If the surface remains rough use another coat. Once the nail is smooth continue your manicure.
