We use an ammonia-free, demi-permanent hair dye glaze to correct, refresh or enhance your hair color. Hair glaze increases hair’s shine and makes permanent color last longer. It usually lasts anywhere from one to two weeks. You can get a hair glaze in two varieties. It can come in both a clear glaze and color glaze. Whichever glaze you end up choosing will work by coating your hair shaft with shine. Think of this shine as being your “top coat” but instead of it being for your nails, it will be for your hair. A color glaze will not only add shine but will also add a semipermanent hair color. The reason that some people prefer getting a color glaze done rather than a permanent color is because while permanent color comes with the problem of different colored roots, a color glaze gradually fades over the course of a few weeks.
