Great
Really good and improved the health of my nails after I damaged them. Recommend if you are needing some added strength to your nails

Great for damaged nails.
I use everyday for a week (and use the CND cuticle exfoliator) then remove it and start again. It's given my nails a chance to grow strong after years of shellac/gel which just made them weak over time. Bare nails looks nice for a change!

Excellent product
Excellent product have preciously been using OPI Nail Envy which was good but seems to of changed formula. This nail hardener has been great, I have started to get my lovely nails back and they are not breaking as they did before. I would recommend it.

I like press on nails, but they literally will destroy your nail beds. When my nail beds are getting weakened, I take a break and use this product with great results. I wouldn’t be without it.
