Nail file 100/180 “Effective”

The best technique for filing your natural nails is to file in one direction, from the outside to the center of the nail, avoiding filing from top to bottom or front to back. Filing in all directions can weaken nails and make them more likely to break. Filing in one direction helps smooth the nail evenly, avoiding cracks and breaks. This gives a cleaner result and helps maintain the strength of the nails.

Filing in one direction is also recommended because it helps prevent nail splitting, a condition where the layers of the nail separate. If you file in opposite directions, you can create stress points that damage the layers of the nail and encourage splitting. Gently filing according to this method is the best approach to maintaining the health of your natural nails.

We choose to recommend the file which can be made of cardboard, or glass, because they are gentle on natural nails. This makes them ideal for filing nails. Their abrasion does not damage the nail or the nail plate, and if you follow the filing technique, indicated above, there is no reason to injure yourself.
Using the sander requires more training, a sort of expertise to position the tip on the surface of the nail or on its edges, so as not to damage the nail too much. The abrasion of the rollers and the speed of rotation quickly create holes or waves on the top of your nail. Once the nail is damaged, it takes between 2 to 6 months, the time for regrowth to find a smooth and beautiful nail.
As always it is a question of personal choice and if you handle the sander with dexterity, it is also a significant saving in time and precision.

The grit for a file is a measure of the fineness of the abrasive surface of the file. The higher the number of grains, the less abrasive the file is.
For example, a file with a high grit (180) is used for nail finishing work, while a file with a lower grit (100) is used for shaping the nail, thinning a gel nail or shorten a capsule.

Grit is expressed as the number of grains per centimeter, and all files have the same grit reference. Easier for you to find your way!

The choice of file depends on your needs.
To file capsules and gel nails, an 80 to 100 grit file is necessary, it can be made of cardboard/sponge, or metal.
If you need to file your natural nails and finish your nails, opt for the 180-grit cardboard/sponge file, or the glass file. Both are much gentler and suitable for your nails, especially if they are weakened.

We recommend a lightly abrasive file for natural nails, so a high grit is preferred, i.e. a grit of 160 and above. If your nails are brittle and fragile, the choice is a minimum grain of 180 or more.
The material of the file is also very important, for natural nails take a cardboard or glass file. Avoid metal files.
