Why Do Hair Scissors Rust? Understanding Stainless Steel & Rust Prevention

Introduction                                     

Many hairstylists believe that stainless steel hair scissors are completely rust-proof, but that’s not entirely true. While high-quality stainless steel resists corrosion, it can still rust under certain conditions. If you’ve ever noticed discoloration or rust spots on your shears, you’re not alone.

In this guide, we’ll explore why hair scissors rust, the role of stainless steel in corrosion resistance, and how to prevent rust to extend the life of your shears.

Why Do Hair Scissors Rust?

Rust forms when iron in steel reacts with oxygen and moisture, leading to oxidation. While stainless steel contains protective elements like chromium, it isn’t completely immune to rust. Here are the main reasons why your hair scissors may develop rust:

1. High Humidity and Moisture Exposure

• Hair salons are moist environments, with constant exposure to water and steam.
• Storing shears in a humid drawer or leaving them wet after cleaning speeds up oxidation.
• Even residual moisture from haircuts can contribute to rust formation.

2. Low-Quality Stainless Steel

• Not all stainless steel is created equal. Cheap or low-grade shears may contain less chromium, making them more prone to rust.
• High-end Japanese steel, such as ATS-314 or VG-10, has superior rust resistance.

3. Chemical Exposure

• Hair products, disinfectants, and cleaning agents can weaken the protective chromium layer in stainless steel.
• Harsh sanitizing solutions (such as alcohol or chlorine-based cleaners) may accelerate corrosion.

4. Improper Maintenance

• Failing to dry shears after washing can leave behind water droplets that promote rust.
• Skipping oiling and lubrication reduces protection against moisture and friction.
• Using the wrong cleaning cloth (such as rough towels) can cause micro-scratches, allowing rust to develop.

5. Salt and Sweat Contact

• Sweat contains salt, which can corrode stainless steel over time.
• If you hold your shears with sweaty hands and don’t wipe them down, rust spots may appear.

Understanding Stainless Steel in Hair Scissors

Hair scissors are crafted from various types of stainless steel, each offering different levels of corrosion resistance. Here’s what you need to know:

1. The Role of Chromium in Rust Prevention

• Stainless steel contains chromium, which forms a protective oxide layer to prevent rust.
• Higher chromium content (typically 10-30%) increases rust resistance.
• Premium hair shears use steel with 13% or more chromium, such as VG-10, 440C, or ATS-314.

2. High-Quality vs. Low-Quality Stainless Steel

• Cheap scissors use 420 stainless steel or lower, making them more prone to rust.
• High-quality Japanese shears (ATS-314, VG-10) resist rust better due to higher chromium and vanadium content.

How to Prevent Rust on Hair Scissors

Preventing rust on your hair cutting shears is easy if you follow proper care techniques. Here are the best ways to protect your shears from corrosion:

1. Keep Shears Dry at All Times

• Never store wet shears. Always wipe them dry after every use.
• Use a soft microfiber cloth to dry both the blades and pivot area.
• Store in a dry place, away from humidity and water exposure.

2. Oil Your Shears Regularly

• Apply scissor oil to the blades and pivot area once a day or at least 3-4 times a week.
• Oil prevents moisture buildup, reducing rust risk.
• Use high-quality shear oil instead of generic lubricants.

3. Clean Your Shears Properly

• Avoid using harsh chemicals that strip the protective chromium layer.
• Use a gentle shear cleaner or rubbing alcohol on a cloth.
• Wipe off all hair and residue after every haircut.

4. Store Your Shears in a Protective Case

• A dry, protective case prevents exposure to moisture in salon environments.
• Silica gel packets in your case absorb excess moisture.
• Avoid leaving shears in humid areas like bathrooms or drawers.

5. Avoid Direct Contact with Hair Products

• Hairspray, bleach, and other chemicals can corrode steel over time.
• Rinse and wipe shears immediately if they come into contact with hair products.

6. Use the Right Cleaning Routine

• Daily: Wipe shears with a soft cloth.
• Weekly: Apply scissor oil and deep clean the pivot area.
• Monthly: Inspect for rust spots and sharpen if needed.

How to Remove Rust from Hair Scissors

If your shears already have rust spots, here’s how to fix them:

1. Use a Rust Eraser

• A scissor rust eraser gently removes surface rust without damaging the blade.
• Lightly rub the affected area and wipe clean.

2. Baking Soda Paste

• Mix baking soda with water to create a paste.
• Apply to rust spots, let sit for 5-10 minutes, and scrub gently with a soft cloth.

3. Vinegar Soak

• Dip a cotton swab in white vinegar and rub the rusted area.
• Rinse and dry immediately to prevent further oxidation.

4. Professional Sharpening

• If rust has penetrated the blade, professional sharpening may be needed.
• A trusted shear sharpener can remove rust while maintaining blade integrity.

Conclusion

While stainless steel hair shears are designed to resist rust, they are not completely rust-proof. Factors like moisture, improper maintenance, and chemical exposure can lead to oxidation.

By following proper cleaning, drying, and oiling routines, hairstylists can prevent rust and extend the lifespan of their shears. Investing in high-quality Japanese steel shears and maintaining them properly ensures that they remain in top condition for years.
