Always use a base coat before applying nail polish to protect your nails from staining. It also helps to even-out the bumps on the surface of your nails.
Don't forget to finish with a top coat. This will prevent chipping and allow the color to last longer.
Besides completing your overall look and presentation, nail colors add fun to your digits. When applying nail color, always begin with your pinkie finger and work inwards. Allow the first coat to dry thoroughly before putting on the second coat.
