1- Always apply a clear base coat to your nail before applying the colour. This will protect your nail from being stained by the colour and makes it easier when it comes to removing the polish.
2- To prevent your nail colour from chipping, apply a single coat of clear polish over the top to seal in the colour.
3- After removing your nail polish you can massage into the nail a mix of lemon juice and Bicarbonate of Soda. You can use a toothbrush to do this. This will remove any nail polish remover, buff the nail and restore a white, healthy shade to your nail.
