Okay, I'll admit it: I've been bad to my nails in the past. Months and months of gel treatments left them in a terrible weak, flakey shape when I eventually had to get the gels removed.
I complained to my Mum about the poor state of my nails and she sent me Nail Envy. Previously, I had been using normal clear nail varnish to try and seal the flakes in my nails, but it would just chip off and make the situation worse. After over 8 weeks of using Nail Envy, I can tell you that my nails are stronger and have hardly any flakeyness. They have also been able to grow longer - previously they would just be so weak they'd bend and split.
I would really recommend people to at least TRY this product if you have bad nails - it's not too expensive and lasts ages (I've been using it 8 weeks and I haven't even used one fifth of the bottle).
There are certain instructions you have to follow with the product, but they are very easy.
1)Start with clean, dry nails. Apply 2 coats of Nail Envy
2)Apply an extra coat of Nail Envy every other day
3)At the end of a week, start the whole process again
You can even wear coloured nail varnish over Nail Envy - it's great as it protects the nail and stops staining!
Bottom line: it's worth giving it a go!
