Why do nails always fall off?

Girls who love to make nails often have uneven nail polish, or their nails will always fall off, but although people's nails are beautiful and lasting, why? Let's have a look. When taking glue, first scrape off the nail polish glue on the back of the brush bar and brush head, leaving only a small amount of glue on the front, otherwise it will be difficult to spread it evenly because of too much glue. When gluing, the brush head should be at a 45-degree angle with the nail surface, and the technique must be light. If you feel that the color is not full after applying it once, you can apply it again, but the amount of glue taken in the second time is less than that in the first time. Remember to cover the edges after smearing. Inclined front end of nail: 1. If the edge is not wrapped well, the fingertips will fall off after several times of nail stress. 2, the nail itself is thin and soft, and the glue is hard after being photographed. When the nail is bent, the nail polish glue is easy to split from the middle. The glue is too thick, the inside is not dry, and the adhesion is not enough. 4. Under normal circumstances, gently polish the front end. If the grinding is not in place or too hard, it will fall off. The back end of the nail will become warped 1, and the cleaning is not in place. There are grease, moisture or other impurities on the nail surface, which will cause the glue to separate from the nail surface. 2. Apply nail polish to dead skin or skin and pull the skin away with glue. 3. If the back end of the nail surface is not polished properly, it is not attractive enough for the subsequent glue and is easy to fall off. The whole piece fell off 1, and there were impurities on the primer or it was not dry. 2. Different brands of primer and nail polish were used, which led to rejection. 3. There are no blanks and no series of painted nails.
