    [Update 10.12.2016] Not only is my nail still whole, but since yesterday I've been doing some crazy housework after repainting the house. I scrubbed nearly every inch of my house using all kind of...

    I wear acrylics a lot and i used to bite my nails a lot so naturally when i let them grow, they're not very strong. I bought it because it's cheap and i like SH polishes in general. I like the...

    I've used nail hardeners for many years but this product made my nails cracked, it looked like I had natural crackled nails. I had to wait for them to grow out so I could again use nail polish.

    My nails were starting to grow longer and harder right before I bought this product. I thought the 'diamond strength' would only improve my nails more, since they usually were weak and flaky. Well...

    i prefer the gold version of it because i think the silver one actually weakens my nails and makes them more prone to splitting. the formula also thickens and dries out quite fast (after 6-8 months...

    My nails are weak and prone to splitting. I paid c. £10 for this and it was definitely not worth the money. I don't think it damaged my nails further as someone else mentioned, but I used it as per...

    I like to use this as a topcoat. my nailpolish lasts longer and my nails doesnt chip as often. But I had to use alot on each nail so the bottle didnt last long.

    Helps prevent nail breakage. I wear nail polish all the time and I use this always before a base coat. I notice my nails don't crack or break at the tips as easily as when I don't use it.

    My nails used to peel a lot, it was really irritating. I picked this up on a whim because I was desperate for something that would help. I've been using it for about two months now and it works...

    I didn't like this product at all. I bought it for $16 (standard in Australia) and was not worth it at all. I used it with such hope and nothing! I tried it as a base coat by itself and it just...

    I wish I could say this worked, because I've tried just about every nail strengthener on the market, but it didn't do anything. Towards the end of the bottle it got very goopy and bubbly. If it's...

    I cannot live without this! If I do, then my nail wants to just break off, so if you are thinking about getting this product, go for it!

    It dries out quickly and lasts for a very very long time. I also like the cute “diamond” on the bottle. I use it as a base coat sometimes. I like it overall.

    After subjecting my usually healthy, strong nails to nail polish week in, week out, they tend to get quite brittle, especially after removing the last of the polish, it looks dry and dull. Two...
