. I have tried so many things and let me tell you, give this stuff a few weeks and your nails will be a lot harder. I can't even bend mine anymore. I use it under my nail polish as a base coat too. It glides on and levels out like a pro.

This is great for growing nails mostly. They do harden but not enough from what I find anyway. Love that they help grow my nails, keep them shiny but you have to go by the instructions to make sure it works right. Re apply after three day for max effectiveness!

LOVE THIS!

I went from splitting, flaking nails to beauty!!

My fake nail friends put this on after they removed their fake ones, it took away the "air" pain instantly.

What can I say about this nail hardener? Other than it is like witchcraft. That is, if you use it twice a week your nails will grow longer and stay strong. When I don't use it regularly, I have noticed that my nails will break and peel easily. It's a little overpriced, but it's worth it.

I have tried different brands of nail hardener and no results. When ever I use witchcraft I always get results after a few days. Love this product and would recommend it to everyone who wants longer stronger nails.

My nails always break and I can not get them to grow unless I use this product faithfully...It is awsome and it dries really fast.

Best nail hardener I have found at a relatively decent price. If you're lucky can find it on sale. Don't be turned off by the smell, it works miracles. Just need to keep applying every couple of days and before you know it your nails will be awesome.

My nails are really thin and as a result didn't grow very well. I've been using this for a year and my nails are amazing. People keep asking if they're real because they're completely strong now and a good length. I'd recommend this to anyone.
