What is the technique called when you take a small section of hair and separate select strands of the section with a tail comb?

The technique referred to in the question is known as weaving. This method involves taking a small section of hair and using a tail comb to separate select strands within that section. Weaving is typically used in highlighting to create a more natural, sun-kissed look. By carefully selecting strands, the stylist can achieve a blend of natural and colored hair, leading to a more dimensional finish. This differs from other techniques; for instance, teasing involves backcombing to create volume, sectioning simply refers to dividing hair into manageable parts, and blending denotes the process of merging colors or textures together. Weaving is specifically focused on selectively highlighting strands for a nuanced appearance, making it the correct answer in this context.
