When adding tortoise color to brown hair, what is the common term for that process?

The process of adding tortoise color to brown hair is commonly referred to as tortoise shelling. This term describes a specific technique that involves blending warm, rich tones—like browns, golds, and coppers—throughout the hair to create a multi-dimensional effect reminiscent of the natural color variations found in tortoise shells. This method aims to enhance depth and add vibrancy while maintaining a harmonious and natural look.

While caramelizing, color blending, and highlights may involve adding warmth or dimension to hair, they do not capture the unique nuances and specific blending style associated with tortoise shelling. Caramelizing typically refers to a method focused on lightening certain areas to achieve a caramelized effect, while color blending generally describes the broader practice of seamlessly integrating different colors. Highlights involve applying lighter shades to the hair, which may not specifically include the warm, rich blend characteristic of tortoise shelling. Therefore, tortoise shelling is the most accurate term to describe this stylistic approach.
