Did you know? Your nails and your nail shape, will tell others a lot about your personality. Let’s look into the different kinds of shapes you can file your nails. Your personality will prefer and choose the shape you will file your nails. During preparation you will shape and file the nails free edge into the shape you prefer. Whether you are going to do a natural nail overlay or an overlay over artificial tips, you will have to shape the nails before any product application. Do not file nails after gel polish application. This may break the seal you created with the cap action over the free edge of the nail, resulting in possible product lifting at the free edge area of the nail.
