Best nail treatment for peeling?

[BeeFarseer]

I swore by Nailtiques formula 2 to sort out peeling, but it's out of stock everywhere.

Can anyone recommend a decent treatment in place of it please? Peeling and splitting before the free edge are my issues.

OPI Nail Envy (the original one) really sorted out my nails when they were thin and splitting. The instructions say to put on two coats, then another coat every other day - but the two coats alone were enough for my nails. I took it off after a week and reapplied it.

I second OPI nail envy, nails are like cast iron now.

OPI Nail Envy it is then!

Thanks @FourEyesGood and @Accountant222
