What is the process of retouching in hair services?

Retouching in hair services specifically refers to the application of color to the roots of the hair. This process is crucial for maintaining the overall appearance of hair color, especially for clients who have previously dyed their hair and are experiencing regrowth. As hair grows, the new roots can be noticeably different in color from the rest of the hair, leading to a less polished look. Retouching ensures that the hair color remains uniform and vibrant from the roots to the ends.

Other options do involve aspects of hair care and styling but do not define retouching. Cutting hair pertains to altering its length or shape, blow-drying is a styling technique to dry and shape hair, and deep conditioning is a treatment aimed at restoring moisture and health to the hair. Each of these processes serves distinct purposes in hair care but does not address the specific need to refresh the color at the roots, which is what retouching achieves.
