Which of the following is NOT a technique related to coloring specific strands of hair?

The technique commonly referred to as Ombre is characterized by a gradual blending of one hair color into another, typically from a darker shade at the roots to a lighter shade at the tips. This method does not focus on coloring specific strands of hair. Instead, it involves creating a broader gradient of color throughout the hair, rather than the precise, strand-specific applications involved in weaving, highlighting, and slicing.

In contrast, weaving, highlighting, and slicing are techniques designed to add color to individual strands or sections of hair. Weaving involves the interlacing of colored and uncolored strands to create a subtle and blended appearance. Highlighting refers to the process of lightening specific strands to achieve a brighter and more dimensional look. Slicing, on the other hand, involves taking neat, straight sections of hair for a more defined application of color.

Therefore, ombre stands apart from these techniques because of its emphasis on a gradient effect rather than targeting specific strands for color application.
