If clean scissors push or fold hair, tension is one possibility, but a damaged edge or screw can feel similar. Find the instructions for the exact model before turning its pivot. The maker’s method matters: Mizutani describes opening its scissors to 90 degrees for a release test; Yasaka describes checking whether the handle closes under its own weight. A fixed angle or number of clicks should not be copied to every screw.
Quick Diagnostic
| What you notice | Check first | Next step |
|---|---|---|
| Blades close under their own weight in the maker’s test | The screw may be too loose. | Adjust only by the maker’s stated method, then repeat its test. |
| Blades resist opening or remain fully open in the maker’s test | The screw may be too tight, or the pivot may need cleaning. | Clean and inspect first; adjust only if the manual directs it. |
| Rough or gritty closing | Hair, residue, a damaged edge or a pivot fault may be involved. | Wipe and oil as instructed. Stop if the problem remains. |
| Hair bends or pulls after cleaning | Tension is one possible cause; a dull or damaged edge is another. | Check the maker’s tension setting, then seek an edge/pivot assessment if cutting still fails. |
Before turning the screw
- Remove hair and product residue; dry the pair and oil only where its instructions specify.
- Identify the maker, model and screw type. A flat screw, ratchet and dial may need different tools and increments.
- Perform that maker’s tension check. Mizutani says to turn its screw one notch at a time and retest. Yasaka asks users not to loosen its fulcrum screw more than necessary.
- Stop adjusting if the screw is defective, the blades protrude or cutting remains poor. Record what you tested for the service contact.
When to Escalate
- A defective or loose screw, protruding blade, impact damage or persistent rough closing needs a maker or specialist assessment; do not force the blades through hair.
- If a clean and correctly adjusted pair still pulls, ask whether sharpening, alignment or pivot service is needed. The symptom alone does not identify which repair will fix it.
