In cosmetology, what is an "overlapping technique"?

An overlapping technique in cosmetology refers specifically to a hair coloring method where new color is applied over sections of hair that have already been previously colored. This technique is often utilized to refresh color, blend out regrowth, or create dimension by mixing different shades. It can be particularly effective for maintaining vibrancy in color-treated hair without requiring a complete color change.

Using this approach allows cosmetologists to achieve a more seamless look, as they can blend the new color into the existing color. It also helps in avoiding stark contrasts between the roots and the lengths of the hair, which can happen if colors are applied in isolated sections without consideration for previously treated areas.

This method, when done carefully, can enhance the overall appearance by creating a more natural transition between colors and ensuring that the hair looks polished and well-maintained.
