How Often Should You Sharpen Your Hairdressing Scissors?
The honest answer is “before you notice”. Five signs your edge is going, what wears it down, and why a proper service every six months costs less than you think.
A dull shear doesn’t announce itself. It creeps up — a little more pressure here, a folded hair there, a client who says their ends feel dry a fortnight after the cut. By the time you’re sure, you’ve been compensating for weeks.
The short answer
For a busy professional, have your shears serviced at least every six months — sooner if you cut a lot of dry, coarse or product-heavy hair, or if you notice any of the signs below. Daily care stretches the time between services; it never replaces them.
Five signs it’s time
- Folding or pushing. Hair bends or slides out of the blades instead of cutting cleanly. The most common first sign.
- Pulling. Your client flinches or the hair snags as you close.
- Ragged ends. Under the light, cut ends look chewed rather than crisp.
- A heavier hand. You’re squeezing harder to get the same result, and you feel it by the afternoon.
- Something you can see or hear. A nick, a shiny spot on the edge, or a gritty feel through the pivot.
A dull blade doesn’t cut hair — it crushes it, then breaks it. That’s where a lot of split ends really come from.
What wears an edge down
| Factor | Why it matters |
|---|---|
| How many clients you cut | More closes, more wear. Simple as that. |
| Dry cutting | Dry hair is tougher on a fine edge than wet. |
| Coarse, thick or chemically treated hair | More resistance through every cut. |
| Product build-up | Residue creates drag and can corrode the edge over time. |
| Drops and knocks | One fall can chip a tip or knock the blades out of alignment. |
| Barbicide | Never leave shears soaking overnight — it’s hard on the steel and the pivot. |
| Steel | Harder steels hold a fine edge longer — see our steel guide. |
Make every edge last longer
- Wipe the blades after every client.
- A drop of scissor oil in the pivot at the end of every day, then open and close a few times.
- Check the tension weekly. Too loose folds hair; too tight wears the blades and your hand.
- Always store them closed, in a case.
- Cut hair, and only hair. Not foils, not thread, not the tag on a gown.

Why you should never sharpen them yourself
A convex edge is ground to a very fine, very precise angle along a curved blade. Home sharpeners and flat stones can’t reproduce it, and one wrong pass can change the blade geometry for good. A proper service is about far more than the edge, too.
What a proper service looks like
Our Scissor Sharpening service takes any brand, for a flat fee, with a minimum of 45 minutes spent on every pair:
- Inspection of the blades and tips under magnification
- A full strip-down, replacing any worn parts (we stock nearly every part)
- Sharpening, resetting the set and adding a fresh ride-line
- Reassembly, alignment and testing until they cut clean
If anything needs extra work, we message you with a price first — never a surprise charge. On a trade account, you pay less.
Questions we get asked
How long does a service take?
We spend at least 45 minutes on every pair and return them next-day by courier once they’re done.
Will sharpening make my shears shorter?
A professional service removes only the metal it needs to. Done every six months, a well-made shear gives you many years of work.
Do you sharpen other brands?
Yes — any brand, same care.
