Which is the best nail strengthener?

[peaceanddove]

I've been a fan of Nailtiques 2 for years but you just can't seem to source it anymore. Can anyone please recommend something similar? x

My mum used to swear that eating a cube of jelly a day worked and to be fair her nails were amazing.

I like Sally Hansen Hard as Nails.

OPI Nail Envy is amazing

I’m missing Nailtiques too, down to the last dregs of my last bottle. Saw some on Amazon this week for £100+ a bottle! I heard that their factory had burned down, don’t know how true.
I’ve bought some Sally Hansen Maximum Growth to try. Nail Envy doesn’t work for me.
