Which cutting technique blends hair from a shorter perimeter to a longer length?

The cutting technique that effectively blends hair from a shorter perimeter to a longer length is tapering. Tapering involves gradually reducing the length of the hair, typically along the edges or the perimeter of a haircut, allowing for a soft transition from shorter to longer strands. This technique creates a smooth blend that enhances the natural flow of the hair and is often used to remove bulk without sacrificing length.

Layering refers to cutting hair at different lengths, resulting in added volume and movement, rather than focusing on a smooth gradient from short to long. Texturizing is primarily aimed at altering the texture of the hair to reduce bulk or create a more lived-in look, but it does not specifically address the blending of lengths. Shagging is characterized by various layers and an overall disconnected look, rather than a blended transition from shorter to longer hair.
