A color correction service is something that involves two or more steps and results in a definite visual transformation. It is a “fix” undesirable color result. Some reasons to get a color correction service includes, but is not limited to, multiple bands of multi-colored tones along the hair shaft, uneven regrowth, brassiness, toning down or brightening of the hair, growing out gray, or correcting a “fashion color” to name a few.
