Look after your hands and nails! Every time you wash them apply a hand moisturiser immediately afterwards whilst they are still damp to lock in moisture. Moisturise cuticles daily using a massaging circular motion and a good cuticle cream. Exfoliate hands once a week using a hand scrub. File nails in one direction only, not back and forth this will avoid nail's splitting. Always use a base coat and a top coat to achieve a long lasting manicure especially when using darker colours.
Here are some of my favorite's
Aveda hand relief cream
Mavala cuticle cream
Champney's softening hand scrub
Seche VITE Top coat
