So in the meantime I have used a protective Sally Hansen basecoat, and then applied a few layers of Barry M in marshmallow.
This has been a huge help for keeping my nails from breaking as, like I said earlier, it's like cement and doesn't allow my nails to bend and break. It's such a pretty varnish too and gives a great nail effect.
I find that it is actually rather easy to remove as it comes off in a big chunk and then remove the rest with varnish remover. However, if it isn't so easy to get off your nails, soaking them in warm water is always a helpful way to ease the varnish off.
