A texturizing technique performed on the ends of hair using the tips of the shears to remove bulk is:

Point cutting is a texturizing technique where the tips of the shears are used to create texture and remove bulk from the ends of the hair. This method involves angling the shears into the ends of the hair rather than cutting straight across, which allows for a softer, more blended finish. It creates subtle layers and reduces weight without changing the overall length of the hair. Point cutting is especially beneficial on blunt cuts or thick hair, as it helps achieve a more lived-in look while still maintaining structure.

Other techniques mentioned, like slicing or slide cutting, involve different methods of cutting that either move through the hair shaft or create more structural changes, which does not specifically focus on the ends as point cutting does. Blending typically refers to merging two different lengths or textures together, which is broader than what point cutting accomplishes. Thus, point cutting is the technique that specifically addresses the removal of bulk at the hair ends using the shear tips.
