Highlights Removal
Q: What are the general techniques for removal of foil highlights? Different techniques are causing some confusion.A: Well, generally speaking, removing foil highlights is usually a simple matter of re-coloring the highlighted hair to match the main color of the hair.
Another option would be to simply apply a deposit-only hair color that is slightly lighter than the main color of the hair, but that is significantly darker than the highlighted hair, all over the head and allow it to process normally.
This will dramatically reduce the difference between the colors of the previously highlighted hair and the hair's main color. The end result will be that the highlights are blended significantly into the main color of the hair and the hair will look as though the color variations are more naturally occurring.
