How Many Teeth Should Thinning Scissors Have? The Real Ladder, Tool by Tool
Share
For your first or only thinning scissor, choose around 30 teeth — the all-rounder count that blends and de-bulks without leaving visible steps. The rule behind every tooth count is directional and it never changes: more teeth take finer, more invisible bites; fewer teeth take bigger, more visible ones. Here's the whole spread explained through real tools with real prices — from a 35-tooth finishing thinner to a 10-tooth channeller — and an honest word about the removal percentages you'll see quoted elsewhere.
The tooth-count ladder, with real scissors on every rung
Every model below states its steel (Japanese Cobalt Alloy) and hardness (58 HRC) on its product page; prices are live as at 21 August 2026.
| Teeth | What it does | In the range |
|---|---|---|
| 35 | The finest blend — invisible finishing, softening lines on precision work | Vampire 35 ($480) · Jada 35 ($400) |
| 30 | The all-rounder — everyday blending and bulk removal, the first-thinner count | Geisha ($395) · Rose Tattoo ($410) · Emperor ($390) · Firebird ($380) · Young Genius ($250) |
| 26 | Texturising — visible movement and softness with more bite per closing | Prodigy ($495) · Diamond ($495) · Vampire 26 ($480) |
| 23 | The bridge — texture work on a shorter 5.5″ blade | Firebird Channeller/Texturiser ($380) |
| 16 | Channelling — deliberate, visible separation and weight carving | Jada 16 ($400) |
| 10 | The chunkiest cut in the range — bold, editorial texture in single closings | Dracula 10 ($695) |
The percentage myth, handled honestly
You'll find pages confidently stating that 30 teeth remove 30% and 40 teeth remove 50%. Be suspicious of all of them — including any that quote us. Removal per closing depends on section thickness, where on the section you close, how many times you close, and the tooth design itself; nobody publishing those percentages has measured your section on your client. We make thinning scissors and we won't quote you a number nobody measured. The direction is what's true, always: more teeth, finer bites, subtler blend; fewer teeth, bigger bites, more visible texture. Choose by the work you actually do.
Thinner, texturiser, channeller — one mechanism, three appetites
They're all a toothed blade closing against a convexed cutting blade; the names mark bands on the same ladder. Thinners (30–35 teeth) remove bulk you shouldn't be able to see. Texturisers (about 23–26) put visible softness and movement in. Channellers (16 down to 10) carve — separation you're meant to notice. The technique side — where on the section, how many closings, why never at the root — is covered in how to use thinning scissors, and the full picture from teeth to left-handed options lives in the complete thinning scissors guide.
Which to buy, in order
First: the 30-tooth from your cutter's family. Matched sets exist for a reason — same steel, same balance, same finishing — and every ShearGenius family prices the set $150–$300 under the two tools bought separately (the second-pair arithmetic is here). Second: the texture tool your work keeps asking for — a 26 if your finish work wants movement, a 16 or the Dracula 10 if your cutting has an editorial edge. Browse the spread on the thinning and texturising collection, or book a free fitting and bring your cutter — matching the thinner to it is exactly what the fitting is for.
Frequently asked questions
How many teeth should thinning scissors have?
For your first or only thinner: around 30 teeth — the all-rounder count that blends, softens lines and removes bulk without leaving visible steps, which is why most of the ShearGenius thinner range (Geisha, Emperor, Firebird, Rose Tattoo, Young Genius) runs 30 teeth. The direction rule is simple: more teeth take finer, more invisible bites; fewer teeth take bigger, more visible ones. Our catalogue spans the whole spread — from 35-tooth finishing thinners down to a 10-tooth channeller.
What do the teeth numbers on thinning scissors actually mean?
The count tells you how many cutting points engage each closing — and therefore how big each bite is. At 35 teeth (Vampire 35 $480, Jada 35 $400) the bites are so fine the blend is close to invisible; at 26 teeth (Prodigy $495, Diamond $495, Vampire 26 $480) you're texturising with a touch more visible movement; at 16 teeth (Jada 16 $400) and 10 teeth (Dracula 10 $695) you're channelling — deliberately carving visible separation and chunks. Same mechanism, different appetite.
What percentage of hair do thinning scissors remove?
Honest answer: be suspicious of any page quoting exact removal percentages per tooth count — those figures vary with how much hair is in the section, how many times you close, where on the section you cut, and the tooth design itself. Nobody publishing '30 teeth = 30%' has measured your section. What's reliably true is the direction: more teeth remove less per closing and blend finer; fewer teeth remove more and show more. Judge the tool by behaviour, not by a percentage nobody measured.
Should my first thinner be a thinner, texturiser or channeller?
A ~30-tooth thinner, and it should match your cutting scissor's family — that's the standing advice in our second-pair guide, and it's why every ShearGenius family sells its cutter and 30-tooth thinner as a matched set ($150–$300 under the two bought separately). Texturisers (around 26 teeth) and channellers (16 down to 10) are second-thinner territory: tools you add when your work asks for visible texture, not before.
Do more teeth mean better quality?
No — tooth count is a design choice, not a quality grade. Quality lives in the same places as any scissor: the steel and its stated hardness (every ShearGenius thinner names both — Japanese Cobalt Alloy at 58 HRC across the thinner range), the convexed cutting blade the teeth close against, and the finishing. A cheap 40-tooth thinner is still a cheap thinner, forty times over.
