Nail strengthener?

[sparkle789]

My nails are really weak, I've used opi nail envy in the past and it was good, but is there anything else that is better?

Truthfully OP? I've found nothing that helps.

Tried everything and it's all temporary fix at best yet never finally resolves the problem long term Sorry not much help!

Nail Envy - honestly it really helps and my nails were the absolute worst.

I thought CND rescue RX was improving mine, but I'm not sure.

I actually think wearing China glaze polish makes the biggest difference.
