Changing a person's hair colour by applying a lightener or hair colour to lift the brightness level of hair strands is known as hair highlighting/lowlighting. Foil highlights, hair painting, frosting, and chunking are the four fundamental types of highlights. Highlights can be any colour as long as they are lighter than the hair around them. Hair that has been bleached or coloured permanently will remain that way until new growth appears. Hair that is highlighted can appear fuller.
