It is a salon service that focuses on applying color to new hair and helping the roots blend in with the rest of the hair. This is usually done every four to six weeks, depending on how fast your hair grows and the contrast between natural and dyed color.

A root touch-up is simply an application of hair color applied to the roots of the hair, to disguise the fact that hair has grown out, and to make a hair coloring last longer.

Start by coloring the roots in all four sections and the hairline as well. Once you are done with the roots you may begin with the rest of the hair starting out on either one of the front sections, Move to each section until all of the hair is saturated.
