OPI nail envy may be an oldie to some but it knows its job and works if you follow the process.

After 1 application my nails felt strong and look instantly healthy. Love the shine too no more peeling nails yeah.

My nails used to be very thin and chipped very frequently, but since using this product, I have been able to grow them out without chipping! I have also noticed that when I use this as a base coat, the nail varnish stays on for a lot longer than usual.

Been using this weekly on and off for the last year since the first lockdown after having acrylics on my nails for two years and my nails were extremely weak and flakey due to this. However now they longer crack/break like they used to. They still get very dry at times but that's mainly due to how much I have to wash my hands at work, so weekdays I use this to protect them and help them grow then let my nails go natural on weekends. Life saver if you're struggling from very cracked nails that won't grow healthily. 

Its brilliant really does make your nails stronger and harder. Wouldn't be without it.
