Which technique is essential for achieving a blended haircut?

The technique that is essential for achieving a blended haircut is point cutting. This method involves snipping the ends of the hair at an angle which helps to soften the lines between different lengths of hair. By creating texture and removing bulk at the edges, point cutting allows for a seamless transition between layers of hair, which is critical for blending.

This technique is particularly useful for avoiding harsh lines that can occur with blunt cutting methods, leading to a more natural look. It promotes movement and flow within the hair, contributing to the overall blended effect.

Other techniques mentioned, such as using a guard on clippers, can help in achieving a uniform length but may not offer the same level of blending finesse, while comb-over cutting, which focuses on directing hair to one side, can create a certain style but does not inherently blend hair lengths. Cutting with a straight line, on the other hand, typically results in a more defined edge and does not contribute to the blending effect that is desired in this context.
