What technique is used to remove bulk from hair?

Thinning is the technique specifically designed to reduce bulk from hair while maintaining length. It typically involves the use of thinning shears or a razor, which selectively removes some of the hair strands, resulting in a lighter feel and more manageable texture without significantly altering the overall length. This is particularly useful for clients with thick or dense hair who want a hairstyle that feels less voluminous and easier to style.

In contrast, layering generally involves cutting the hair at varying lengths to create shape and movement but doesn't directly address bulk removal. Texturizing can also help in reducing bulk and creating softer, more interesting looks, but it focuses more on shaping the hair's surface and enhancing its movement rather than strictly eliminating volume. Blending is usually related to seamlessly transitioning between different lengths or colors in hair but does not primarily aim to reduce bulk. Therefore, thinning is the most accurate term that specifically pertains to the removal of bulk from hair.
