O1. Remove any chipped nail polish that might make your nails look ugly.
O2. Use a cuticle pusher to push back your cuticles. This helps prevent them from cracking. You can also use some lotion to make them soft and not dry.
O3. Trim your nails with a nail clipper, then make sure their filed evenly. Some girls like longer nails, but some like shorter. All that matters if they're even in length.
O4. Put a clear basecoat on your nails. This will protect them, even if you don't want to paint your nails. If you do paint your nails, it will prevent the polish from staining your nails.
O5. Drink a lot of milk and eat a lot of food with calcium. It helps strengthen your nails (and hair and bones too!)
O6. Don't put nail polish on too often. Once a week is the most you should be painting your nails. The chemicals in the polish and the remover are harsh and can dry out and damage your nails. Also, try to avoid fake nails because they can also damage your natural nails.
O7. Don't be afraid to express yourself with your nails. You can always change your style and try different colors, patterns, and designs!
