How to Tell If Your Shears Are Dull (Before They Ruin a Cut)

A dull blade rarely looks dull. The bevel can look perfectly clean under salon lighting while the edge itself has already rounded off just enough to start crushing hair instead of slicing it. Waiting for shears to look dull means you've usually been cutting with dull shears for weeks.

Better tests than eyeballing the blade:

• The single-strand test: hold one strand of hair with light tension and cut without sliding the blades. A sharp shear severs it cleanly with almost no pressure. A dull one pushes the strand, bends it, or takes visibly more force to close through it.
• The listen test: sharp shears cut quietly. A faint crunch or snapping sound instead of a clean snip usually means the edge is folding hair rather than cutting it.
• The client tell: if you're noticing more split ends right after a fresh cut than you used to, that's the hair shaft getting crushed at the point of the cut, not a haircare problem on the client's end.
• The fatigue tell: if your hand or wrist feels more worked by the end of the day than it used to for the same volume of clients, you're compensating for a blade that needs more force to close.

Why the paper test alone isn't enough: paper and hair cut differently — a shear can glide through paper and still crush hair, because hair has give that paper doesn't. Use the strand test as the real check, not paper.

Catching dullness early protects the hair you're cutting today and the edge itself — the longer you cut on a rounding blade, the more metal has to come off to restore it next time.
