I have really struggled with my nails flaking and peeling in recent months. Have tried oils, leaving them bare, changing nail varnish removers, hardening varnishes, you name it.
Anyway a thread on here recently (which I can't now find!) was posted about the exact same issue and several posters recommended OPI Repair Mode bond building serum. You apply it to bare nails twice a day for a week. I baulked a bit at the price but bit the bullet.
I am SHOOK by how effective it is. I am on day 4 and my nails are transformed. Even though the flaky bits are still there, they are sort of stuck together if that makes sense? And the condition of my nails has improved ten fold. It's genuinely miraculous!
So I wanted to share in case anyone else is struggling with this. This OPI thing is a game changer! And I am absolutely promise I am not on commission or in any way associated with it - just genuinely blown away but how well, and how quickly, it has worked.
