This product is amazing at strengthening your nails. Worth every penny. 

Hardener is easy to apply but careful not to get it on surrounding skin as it will go hard! The consistency is not like varnish it's more of a liquid. I'm not sure if it's helped with my nails of not as after 2 weeks use they've gone from soft and flakey to quite brittle so still snapping. I'm going to persevere though.

My nails were left weakened after years of wearing nail gel. I purchased this in the hope of supporting nails repair and boosting the health of my natural nails. Particularly as my nails were very thin and prone to tearing. It works fairly well, I noticed improvement in the tearing as well as overall thickness. Requires frequent re-application. Did it work well enough for me to buy again? No - I'm satisfied but will try other brands once this is finished.

Helped me to grow long & strong nails for the first time in my life. Very satisfied with this purchase and will be sure to stock up again!

I have used this product for over 40 years o iknow just how good it is!

I have extremely weak bendy nails that peel and tear constantly. I have been applying this 2 times a day, 2 layers every time I use it. I have seen a noticeable difference in about 2 weeks and I would recommend to anyone who really struggles with weak nails!!! 

Just started using it and I see my nails are a bit better but still brittle. Need to keep using and hope it will improve with more time using it

Have been using this a few weeks now and not seeing any difference it's a shame as reviews looked good

This is great hardener, my nails were very brittle all my life, I discovered this product by chance and using for about 4 months. My nails improved dramaticaly,however I'm using it about three times a day and apply twice on whole nail not just tip as advised.They are so strong and shiny.

I purchased this a few weeks ago as I bit my nails for over 30+ years and now I have given up the awful habit I find that my nails are very weak and can peel. This has to be one of the best products out there - and I have tried a lot - as already my nails are considerably stronger and not peeling. The only mild annoyance is that if you put too much product on your nails look a bluey/grey colour, although that does wash away after a few hand cleanses As you don't use a lot of this product when applying correctly, I can see the bottle lasting quite a while. To me this is worth every penny and I highly recommend it to any others who have similar problem nails.
