What a 12 Guard Haircut Looks Like
A #12 is the longest common clipper guard. It leaves real length that falls, waves or curls, and it looks like a scissor cut that has simply been evened out.
Who a #12 Haircut Suits
- Low tapers with longer hair on top
- Curly and wavy hair that you want even without losing volume
- Men growing their hair out who still want it tidy
- Quick at-home trims on longer short styles
Popular #12 Combinations
- 12 guard low taper: a #1 to #3 taper at the neckline and ears, #12 everywhere else.
- Textured top: #12 on top, then point-cut with scissors for texture.
- All-over #12: a simple, even trim.
How to Ask Your Barber
Say the guard number and where you want it, for example “#12 with a low taper”. Not every barber uses a #12, so you can also ask for “an inch and a half on top”.
How Often to Get It Cut
