The Original Nail Envy by OPI is a nail strengthener with the very hardest base. It consists of hydrolysed wheat protein and calcium in order to provide the required level of stability for heavily damaged nails. You can look forward to longer, harder and stronger natural nails after approximately 6 to 8 weeks.
Apply a layer of the Nail Hardener using the brushes each day without removing the old layer. Then remove all of the layers on the fourth day and start again.
