What Is Nail File Grit?

(If you see two numbers, youre likely looking at a double-sided file.)

The lower the number, the more abrasive the file is, says Meesh.

You may also see them labeled as simply coarse, medium, or fine.

Why does it matter?

An 80-grit nail file (more abrasive) can tear apart and damage natural nails.

In other words: You need the right tool for the job at hand.

What Nail Grit Do I Need?

Anything below 180 works for nail enhancements, she adds.

Once you get that initial cured layer off, you could soak the rest with acetone.

It will do irreparable damage.

The fine-grit nail files usually start at around 400.

If your nails are naturally very weak, err on the higher (finer) side.

What Is the Best Nail File for Natural Nails?

Does the Shape of the Nail File Matter?

In terms of the ability to help you create your look, nope.

The shapesrounded, half-moon, blockare really about what youre most comfortable using.

Buy a few cheaper files and experiment with what shapes work best for you and your desired look.

Is it Worth it to Spend More on a Good Nail File?

Really cheap nail files do work, but the quality isn’t the best.

That quality makes all the difference if youve set up shop at home.

My favorite for filing natural nails are diamond or glass files that can be cleaned and reused many times.

I also disinfect the file after every use and replace it every few months.

And if the file isnt working as well, thats an indicator that its time to replace it.

The file wont shape as quickly or as well over time.
