Final answer:
For natural nails, a fine grit file ranging from 240 to 600 is recommended to prevent damage. Lower grits like 80 or 100 are too abrasive and suited for artificial nails. Gentle filing in one direction with light pressure is crucial to maintain nail integrity.
Step-by-step explanation:
When working with natural nails, it's essential to use the correct grit file to prevent damage. Grit refers to the number of abrasive particles per square inch on a nail file, and the higher the number, the finer the grit. For natural nails, a finer grit is recommended to gently shape and smooth the nail without causing splits or frays.
Typically, a 240 to 600 grit file is best suited for natural nails. The 240-grit file is used to shape the nail, while the higher grits, like 600, are used for smoothing and finishing touches. It's important to file in one direction and use light strokes to avoid weakening the nail structure. Coarser grits, such as 80 or 100, are too abrasive and are generally used for artificial nails where more bulk needs to be taken down quickly.
Another aspect to keep in mind is the pressure you apply while filing. Even with a finer grit file, too much pressure can cause heat and friction, which can also damage the natural nail. Gentle, consistent strokes will ensure a smooth finish without damage. As for the technique, holding the file flat against the nail and using a sweeping motion from the side to the center of the nail gives the best results. Maintaining your nail files and replacing them when they are worn out is also crucial for nail health and hygiene. In summary, using the appropriate grit file and technique will keep natural nails strong and healthy.
