Why Hair Cutting Shears Get Dull (And How to Keep Them Razor-Sharp)

As a hairstylist, your shears are more than tools—they’re an extension of your craft. But even the best-quality scissors will dull over time, and when they do, they can cause split ends, frayed cuts, and unnecessary strain on your hands. Understanding what causes shear blades to dull—and how to prevent it—can help extend the life of your tools and maintain precision in every cut.

Common Reasons Hair Shears Become Dull

1. Improper Cleaning and Maintenance

Residue from hair products, moisture, and natural oils can build up on the blades and dull the edge over time. If left uncleaned, this buildup can also lead to corrosion.

2. Cutting Non-Hair Materials

Using your shears to cut anything other than hair—like foil, plastic, rubber bands, or paper—will rapidly destroy the edge. These materials are too abrasive for hair shears and can cause micro-nicks in the blades.

3. Poor Storage Habits

Tossing shears into a drawer or leaving them uncovered exposes the blades to unnecessary contact, which can lead to dings and misalignment. Dropping them—even once—can permanently damage the cutting edge.

4. Lack of Regular Sharpening

Even if you’re careful, all shears dull with use. Waiting too long between professional sharpenings can strain your hands and lower the quality of your work.

How to Keep Your Hair Shears Sharp Longer

1. Clean After Every Use

Wipe down your shears with a soft cloth or alcohol wipe after every haircut. This prevents product buildup and helps prevent rust, especially near the pivot screw and cutting edges.

2. Use Shears Only for Hair

Never use your professional shears to cut anything but clean, dry, or damp hair. Keep an inexpensive pair of utility scissors nearby for other salon tasks.

3. Store Them Properly

Always store your shears in a protective case or sleeve when not in use. Magnetic shear holders or padded pouches are ideal for keeping them safe from drops or scratches.

4. Oil the Pivot Area Regularly

A drop of shear oil at the pivot keeps the movement smooth and reduces wear on the blades. This small habit makes a big difference in preserving alignment and sharpness.

5. Schedule Regular Professional Sharpening

Get your shears sharpened by a professional every 3–6 months, depending on your usage. Don’t wait until they’re “really dull”—by then, the edge may already be damaged.

Signs Your Shears Need Sharpening

• You're pushing or pulling hair to complete a cut

• The blades feel “rough” or tug at the hair

• You hear a crunching sound when cutting

• You're working harder than usual to close the blades

If you notice any of these signs, stop using the shears and send them for sharpening. Continued use will cause more wear and potentially shorten the lifespan of your shears.
