Which technique helps in blending short hair into longer sections during a haircut?

Slide cutting is a technique utilized to blend short hair into longer sections during a haircut because it allows for the gradual merging of different lengths. This method involves sliding the scissors along the hair shaft rather than cutting straight across, which creates a softer and more natural transition between varying lengths. As the scissors glide through the hair, they remove weight and add texture while maintaining the overall shape, resulting in a well-blended look without harsh lines.

Other techniques, while they each have their purposes in hair cutting, don't serve the specific function of blending as effectively. Point cutting is primarily used to add texture and soften the ends of hair, but it does not create the same smooth transition from short to long. Texturizing focuses on removing bulk from the hair for volume or movement, but again, it doesn’t specifically address the blending of distinct lengths. Layering creates different lengths within the hair but can lead to a more structured look rather than the soft blending that slide cutting achieves.
