Enriched with moisturising and strengthening vegetable oils and extracts, the treatment Nail Hardener & Base Coat achieves a strong base for the nails. The "5-Free" product maintains the natural oil balance of the nails and protects them from splitting, tearing or peeling. The nail hardener is suitable as a base coat before painting or as a top coat for daily use on unpainted nails to provide them with important nutrients and also achieve a shine effect.
