Keep your nails short. Nail Polish users should see that it does not chip off into the food. For reasons of hygiene and for the multi million dollar cosmetic industry. It takes five months for nails to replace themselves. Grow nails only if you can keep them clean.
Short nails make less trouble.
Clip nails short, along their shape. Don't cut them so close that it pinches the skin. A healthy body ensures healthy nails. Brittle or discoloured nails show up deficiencies or disease conditions. Do not keep your nails painted continuously.
