What happens during a color correction?
Besides, what is considered a color correction?
CK: The term color correction refers to using any and all hair coloring services required to correct previously colored hair or to restore hair's integrity.
Then, how long does it take for a color correction?
In some cases, a color correction can be fixed in a few hours. However, in most cases, it will take either one very long session, or multiple sessions spread out over a few weeks, to get your hair looking beautiful and healthy once again.
Its because your hair doesn't have any warm pigments to hold onto that darker color. Some color corrections are much easier than others and may take a whole day or several weeks to accomplish. Typically a color correction can be very costly, time consuming, and can be very damaging to your hair.
