Nail File Guide
Nail Files differ by their measure of Grit and shape. You should always match the right nail file for the job, different grit should be used for natural nails than those that should be used for gel removal or other products on the nail.
The level of Grit is always mentioned on the nail file, the higher the Grit the softer the nail file is. Grit usually ranges from 80 - 280 Grit.
The reason for the difference in nail file grit, is because our natural nail is much more volunerable than product we apply to the nails, and filing it with a coarse nail file will damage and thin the nail.
When filing the natural nail, we should always use the gentle nail file of 180 Grit and above. An important part of nail preparation for extension or gel overlay in general, is to rough up the surface of the nail so it isn't completly smooth. Those tiny scratches on the nail help the gel adhere to the nail and not to peel off fast. For this part of the nail preparation, make sure to use the gentle nail file.
When filing off product from the nail, we can aim for a lower grit of 100, since we want to remove more product with each stroke of the file. Shaping extended nails with product is more efficient when using a lower grit. Trying to file off gel with 180 grit can take forever.
In addition, nail files can be thin or thick, thin nail files can be used in thin or narrow spaces, so they are good for filing under the nail sides, or close to the cuticle. This nail files provide more resistance and durability when filing off hard product.
Finally, remember that nail files, as well as other manicure tools, should not be shared by multiple people and should not be used after they have worn out. A good tip for not having to buy multiple nail files is to use a nail file stainless steal body with a slip on or sticker grit line. Staleks offers great solutions for these kind of one use filing strip on a tool that can be disinfected and sterilized.
