A nail strengthener to solve all nail problems from splitting, peeling, brittleness, etc. This is the matte formula of OPI’s original Nail Envy. It is excellent if you don’t like over-shiny nails or shouldn’t wear make-up, so great for men and health care workers.
It is a treatment, so there is a weekly course of applications which are repeated each week until you are happy with your nails, however you can continue to use it as a regular application to maintain strong nails.
The full size product is 15ml, though some kits contain 3.75ml travel sizes.
