What is the process of thinning hair to graduated lengths while keeping the blades partially opened called?

The process of thinning hair to graduated lengths while keeping the blades partially opened is known as slithering. This technique allows stylists to create movement and remove bulk without affecting the overall length of the hair. By partially opening the shears, the stylist can glide the blades along the hair shaft, which results in a softer, more textured appearance. This method is particularly useful for fine or thick hair, as it can enhance the hair's natural shape and texture, contributing to a more balanced and styled look.

While layering is a technique that involves cutting hair at different lengths to create volume and shape, it doesn't specifically involve the thinning aspect with partially opened blades. Texturizing, while similar, typically focuses more on adding texture rather than just thinning out the hair. Clipping generally refers to using clippers, typically for shorter haircuts, rather than the thinning process described in the question.
