what is a root shadow

A root shadow is a hair coloring technique in which a darker shade is applied directly to the roots, creating a seamless contrast. This technique is also known as a root smudge or root melt. It is a low-maintenance hair color technique that is great for clients who want to refresh their look and add depth and dimension to their hair color. The root shadow technique is achieved by applying a darker color to the roots, which blurs or "shadows" the area where the highlight and natural color meet without completely covering up the highlights. This technique can be done on any shade of hair, but it is particularly popular among blond-haired clients. The result is a subtle, lived-in look that extends the life of the color by fading into the natural roots, instead of leaving a harsh demarcation line.
