What specific portion of the hair is defined as the cosmetic regrowth area?
Answer
The section of virgin hair closest to the scalp, typically an inch or less
Cosmetic regrowth refers exclusively to the newly emerged hair at the base of the scalp that has not yet undergone chemical treatment. This area is distinct from the rest of the hair because it maintains its original texture, porosity, and natural color. Because this hair is untouched by previous dye applications, it requires a specific approach during color services to ensure that the new color matches the existing lengths without creating a visible line of demarcation. Addressing only this specific inch of growth is critical to avoid overlapping chemicals onto previously processed hair.
