Keep nails strong and healthy with the OPI Matte Nail Envy Treatment; a strengthening formula developed for weak, damaged nails. Enriched with hydrolysed wheat protein and calcium, the high-performance treatment helps to renew beautiful nails, whilst working to deliver a long-lasting matte finish. The look of peeling and splitting is minimised, as the illusion of strong, healthy nails is encouraged. Can be applied as a base coat, or over your favourite nail colour for salon-worthy results.
