Nailner Ultimate All-in-One Nail Hardening Treatment – Nail Polish Strengthener – Clear Nail Varnish – Nail Strengthener for Damaged Nails – For Stronger, Harder, Healthier-Looking Nails – 10ml

Works well.

This nail hardener is very good. It goes on well and dries quickly. I apply it twice a week as recommended. My nails do not flake as much and I have no more breakages. I recommend it.

Read the reviews before purchasing and it's as good as the reviews, just be aware of the smell as it's drying ! Be warned it's not pleasant

This nail harder is amazing. Got my nail done and when the fake ones came of so did most of my nail . I tried everything and then I bought this . My nail are beginning to grow as soon as you put it on you feel it getting heavy. Before everyday they would break, now there getting longer and strong. Great stuff.

First time I used it everything was fine. Second time I applied it was ok but after a day I did some washing in hot water and it went gooey.Wouldn’t recommend it

This is marvellous for strengthening nails.

This nail hardener is absolutely superb! My nails were soft and tore easily. When I painted this on my nails they were instantly stronger, prevented tearing and allowed my nails to grow naturally. After a couple of weeks or so my nails had improved so I can use a coloured nail varnish. Really pleased with results of this hardener. My nails are stronger and I can even leave the hardener off if I want to, without my nails being torn or damaged in any way. Excellent hardener!

Dissapointed. Didn't see any difference in my nails at all. Used for over 6 weeks. Also it has a very odd smell to it
