Why does my nail varnish always chip?

[APocketfulOfStars]

I can never keep my nails looking nice for more than a couple of days.I assumed it was a mixture of too much washing up and cheap nail varnish, but even a lovely OPI set, with base coat, colour and top coat did this....in less than 24 hours. What can I do to make them last longer??

Shellac does not ruin your nails. It's the removal process that ruins them if not done correctly. The shellac should be removed by soaking thoroughly in acetone and not just filed off. A decent nail technician would do it correctly. My nails have never been in better condition since having shellac every two weeks for the past few years.
