If you like having polish on your nails, you should not apply polish while there is lotion, oil or any previous polish on the nails; apply the polish only when the nail is sparkling clean.Also, always use a base coat before applying the nail polish. The base coat aids in extending the life of the polish. Also, the base coat prevents the nail from constantly breaking and from the yellowing of the nails from the nail polish. Strong and shiny nails are an indicator of good nail care and good nutrition. Whereas chafing, breaking and dirty nails scream of unkemptness, irresponsibility and dirtiness.
To avoid being labeled as dirty or unkempt, take proper care of your nails!
