Hair Scissors Alignment: How to Set the Tension
Even the sharpest pair of hair scissors can underperform if the tension isn’t properly set. Correct alignment ensures smooth cutting, reduces hand strain, and extends the life of your blades. Learning how to adjust the tension is a fundamental skill for any stylist or barber.
Why Tension Matters in Hair Scissors
Hair scissors function best when the blades glide together with the right amount of resistance. Poorly set tension can cause several issues:
- Too Loose: Scissors fold or bend hair instead of cutting cleanly.
- Too Tight: Excess strain on your hand and faster blade wear.
- Misaligned Blades: Uneven cutting and possible long-term damage.
How to Test Scissors Tension
Here’s a simple test stylists use to check alignment:
- Hold the scissors vertically by the finger hole.
- Lift the thumb blade to a 90-degree angle.
- Release it and observe the movement.
If the blade closes fully, the tension is too loose. If it barely moves, the tension is too tight. The correct setting allows the blade to close about two-thirds of the way.
Steps to Adjust Hair Scissors Tension
1. Identify the Screw Type
Most professional scissors have an adjustable screw. Some may require a special tension key, while others can be adjusted by hand.
2. Turn Slowly
Make small, gradual turns. A quarter-turn is often enough to achieve the desired setting.
3. Retest After Adjusting
Perform the tension test again after each adjustment to ensure the blades are aligned correctly.
Best Practices for Long-Term Alignment
- Check tension daily before starting work.
- Avoid over-tightening, which accelerates wear.
- Clean and oil scissors regularly to maintain smooth movement.
- Seek professional servicing if tension screws become loose or stripped.
Signs Your Hair Scissors Need Professional Help
If adjustments don’t resolve folding, snagging, or uneven cuts, your scissors may need professional alignment or sharpening. Continuing to use poorly aligned scissors can worsen damage and impact your work quality.
Final Thoughts
Proper tension and alignment keep your hair scissors cutting smoothly and comfortably. By learning how to test and adjust tension, you’ll protect your tools, improve precision, and reduce hand fatigue during long workdays.
