The language your hairdresser use can be confusing sometimes, so if you're getting haircut it would be helpful to familiar yourself with these terms:
Layering: This technique removes weight by cutting shorting pieces that falls above your desire length. So, instead of having a haircut that is one length (or blunt cut), it is layered.
The layers can be manipulated to frame the face, add texture, curves and flow.
Movement: Do your hair feel bulky and heavy? Then your hairdresser will use several cutting techniques to create space and freedom in your haircut so it will have lots of movement.
One-Length Cut: This means all the hair will reach the same length. Edgy and strong geometric shape styles usually require this type of cut. The purpose is to provide a solid structure and a bold dramatic line.
Thinning out: Also known as taking weight out is a cutting technique that focus the interior. So, cutting hair from the inside to remove bulk and density.
Under-cutting: This is mostly used for men cuts. Think of the half-shaved style.
