Short answer: hair cutting scissors remove length with two smooth blades, while thinning shears remove bulk with one toothed blade that only cuts the hair caught between its teeth. Most stylists and barbers need both: a 5.5–6.5″ cutting scissor for shape, and a thinning or blending shear for weight, texture and soft lines.
What do thinning shears actually do?
A thinning shear has one straight blade and one blade with teeth (also called notches). When you close the shear, only the hair that falls into the grooves between the teeth is cut, so a single cut removes a percentage of the section instead of all of it. That is why thinning shears are used to remove weight from thick hair, blend clipper lines into scissor work, soften blunt edges and add texture.
Teeth count: how many teeth do you need?
The number of teeth, and the space between them, decides how much hair each cut removes. As a rule of thumb:
| Teeth | Usual name | Hair removed per cut* | Best for |
|---|---|---|---|
| 6–15 wide teeth | Chunking / texturising | 40–60% | Bold texture, piecey looks, very thick hair |
| 18–30 teeth | Thinning | 25–40% | Removing bulk, everyday weight control |
| 30–40 fine teeth | Blending / finishing | 10–20% | Softening lines, blending fades, fine hair |
*Approximate — the result also depends on how close to the root you cut and how many times you close the shear.
Thinning vs texturising vs blending shears
- Thinning shears remove weight evenly without leaving visible lines.
- Texturising (chunking) shears have fewer, wider teeth and take out larger pieces for a deliberately broken-up finish.
- Blending shears have many fine teeth and take very little hair — ideal for finishing a fade or softening a fringe.
- Double-sided thinners have teeth on both blades and remove less hair per cut than single-sided shears, which gives a softer result but takes longer.
When to use cutting scissors instead
Use a smooth-blade hair cutting scissor whenever you want to change the length or the outline: blunt cuts, layers, point cutting, slide cutting and precision lines. Thinning shears cannot create a clean perimeter; they are a finishing tool. If you only own one tool, choose a cutting scissor — you can point-cut to soften lines, but you cannot shorten hair with a thinner.
How to use thinning shears without damaging the haircut
- Start with clean, combed hair and take small sections.
- Cut at least 2–3 cm (1 inch) away from the scalp so short hairs do not poke through the top layer.
- Close the shear once, move down the section, and check before cutting again — it is easy to over-thin.
- Angle the shear vertically or diagonally for blending, and horizontally only when you want to remove weight at a specific line.
- Avoid thinning the fringe line and the perimeter of a bob unless you want a softer, broken edge.
What to look for when buying
- Steel and hardness: hardened stainless steel keeps the edge longer and resists corrosion from water and products.
- Tooth finish: V-shaped or micro-serrated teeth grip hair so it does not slide out of the blade.
- Tension screw: an adjustable screw lets you set the blades so they close smoothly without folding hair.
- Handle: offset handles reduce wrist and thumb strain over a full day of cutting.
- Size: 5.5–6″ is the most versatile for both stylists and barbers.
Our hair thinning scissors are hand-finished in our Sialkot workshop with adjustable tension screws, and you can buy them as a pair with a cutting scissor in our barber and hairdressing kits.
Frequently asked questions
Can I use thinning shears on short hair?
Yes. Thinning and blending shears are widely used in barbering to blend clipper work into scissor-over-comb sections. Use a blending shear with many fine teeth so you do not leave holes.
Do thinning shears cause frizz?
Thinning very close to the root on curly or frizz-prone hair can create short hairs that stand up. Thin from mid-length to ends instead, and use fewer cuts.
How many teeth should my first thinning shear have?
A 25–30 tooth single-sided thinner is the most versatile first choice. It removes a moderate amount of hair per cut and works for most hair types.
How do I clean thinning shears?
Wipe the blades after each client, remove hair from between the teeth with a soft brush, dry them completely and put a drop of scissor oil on the pivot once a week.
