As a nail technician, one of the most important aspects of your job is to ensure the health of your clients' nails. While techniques and products are critical, the tools you use also play a significant role. Among these tools, professional nail files are indispensable, and selecting the correct grit can make all the difference in maintaining the health of natural nails. Here’s why choosing the correct grit professional nail file is so crucial. 

Understanding Professional Nail File Grits

Before diving into the importance of choosing the right grit, it’s essential to understand what grit means. Nail file grit refers to the coarseness of the file. Lower numbers indicate a coarser grit, while higher numbers indicate a finer grit.

  • 120/180 Grit: This file is medium-coarse and medium-fine, ideal for shaping artificial nails and refining enhancements. It is generally too harsh for natural nails. 
  • 220/240 Grit: This file is medium-fine to fine, perfect for shaping and smoothing natural nails without causing damage. 

The Importance of Correct Grit for Natural Nails

  1. Preventing Damage: Natural nails are delicate. Using a coarse file, such as a 120/180 grit, on natural nails can lead to excessive thinning and weakening. Over-filing with a coarse grit can create splits in the nail, making them more susceptible to breaking and peeling.
  2. Maintaining Strength: Natural nails have a balance of flexibility and strength. Using a finer grit, such as 220/240, ensures that you remove only the necessary amount of nail, maintaining their structural integrity. This prevents the nails from becoming too thin and brittle. 
  3. Smoothing Edges: Rough edges and snags can lead to further damage and breakage. A 220/240 grit file allows for precise and smooth filing, eliminating jagged edges that can catch and tear. This is especially important for clients with naturally weak or thin nails. 
  4. Client Comfort: Clients often feel the difference between a coarse and a fine file. A finer grit is gentler on the nails and less likely to cause discomfort during the filing process. Ensuring a comfortable experience can lead to better client satisfaction and loyalty. 
  5. Professional Results: Using the correct grit ensures a professional finish to your manicure services. A 220/240 grit file gives nails a smooth and even edge. This can enhance the overall appearance and longevity of the manicure.  

Tips for Using Nail Files on Natural Nails

  • Always File Dry Nails: Wet nails are more prone to splitting. Ensure nails are completely dry before filing. 
  • Regularly Replace Files: Worn-out files can be less effective and may harbour bacteria. Replace them regularly to maintain hygiene and efficiency.
