What is a root smudge?

A root smudge is a hair coloring technique where the color is applied to the roots of the hair to create a seamless transition between the natural hair color and the dyed color. This technique is commonly used to cover up grey roots or to create a more natural-looking contrast between the roots and the rest of the hair. Root smudges can be done in a variety of shades and can be customized to match the client's desired look. It is a popular choice for those looking for a low-maintenance hair color option that still looks polished and put-together.
