Thinning Shears
Q: What's a good number of teeth in one-sided thinning shears to avoid thinning the hair too much?
A: The number of teeth in thinning shears definitely matters, but it’s not the only - nor the most important - factor when it comes to avoiding over-thinning. The real key lies in how you use the shears. A single, controlled pass is usually all you need. Making multiple passes can easily remove more hair than intended, regardless of the shears’ design.
• Shears with more teeth (30–40 teeth) remove less hair per cut. These are great for general use, especially on fine to medium hair. They create a soft, blended look without leaving harsh lines.
• Shears with fewer teeth (20–30 teeth) remove more hair with each cut. These work best on thick, coarse, or very curly hair, where they can add texture and reduce volume quickly.
• Tooth design matters, too: Finely spaced, narrow teeth are ideal for precision and blending, while wider teeth with more space between them are better for removing bulk.
Tips for best results:
• Make one cut along the hair length between one-quarter of the way from the scalp and one-quarter of the way from the ends.
• For extra thick or long hair, consider two cuts: one at the 1/3 mark and another at the 2/3 point along the hair's length.
• Always test your shears on a small section before committing to a full cut, especially with a new client or unfamiliar hair type.
And remember the golden rule: you can always take more off, but you can’t put it back once it’s cut.
