Step 1: Disinfection, correct the shape of the nail with the sanding strip.

Step 2: Apply a base coat, apply a layer of calcium base coat to the nail surface, let it dry. The base coat can make the nail polish color last longer, and helps prevent pigmentation. When applying the base coat, follow the brush order of first the middle, then both sides.

Step 3: Apply the color. First, shake the nail polish vigorously to mix evenly. Use a brush to apply a small amount of nail polish (the first time should be less rather than more), and lightly test it at the bottle mouth. Adjust the brush to be smooth, and apply the nail polish quickly. Paint in three strokes, starting from the middle of the nail base and moving towards the tip. The brush should be slightly flat, and the bristle should be slightly pressed open. Then, apply another stroke along the sides of the nail.
Note to leave a gap under the half-moon shaped white area of the nail to allow for nail breathing. You can also first apply the nail polish fully, and then use a remover to wipe away the lower edge, while skilled operators can leave the gap and then apply the nail polish fully.

Step 4: Second coating, most nail polishes can make the color more full and lasting after a second coating, fully showing its true color. When applying the first time, the brush should be thin, and the second time, you can apply it thicker. Generally, nail polish peels off from the top of the nail, so applying the nail polish at the top of the nail can prevent this from happening.

Step 5: Apply a top coat. A final layer of top coat can enhance the luster of the nail polish and prolong its durability. It is especially important for glitter nail polish, as a top coat can prevent the glitter from falling off.

Step 6: Dry quickly. The simplest method is to use a quick-dry spray to quickly dry the nail polish. You can also use a hair dryer, or immerse your fingertips in ice water to speed up the drying process. Do not use hot water to wash your hands before the nail polish dries completely, as this may cause the polish to lose its shine.
