I On Nails: Ultimate Nail Strengthener, Growth & Repair, Clear Polish Hardener, Keratin Treatment for Damaged Nails - Hard as Nails Elixir.

Works great. My nails are strong and long now. This is the best product I have. I tried so many and they are a waste of time and money. I tell everyone about this product. It is worth a try.

My nails were paper thin after having gel nails put on 3 times and taken off with a shaving method that ruined my nails. This worked in fixing my nails in less than 6 months! They are as strong and beautiful as they used to be.

Helps brittle nails

I love this nail hardner.

Buy it .. I buy a lot of nail strengtheners and this one stays; doesn’t peel off doesn’t burn actually does what it says ! Use twice a week.. I leave on for a little over a week then take it off and start over ! Definitely worth it and I’ll be buying again !

I have great results with growing out my nails when I use this regularly.

Ayuda con la reparación de las uñas

I did not personally notice any benefits to my nails. I will say that I have terrible nails. They are brittle and chip very easily so this product may be helpful for Others but for someone who may need extreme strengthening properties, this may not be the one.
