Hair highlighting/lowlighting is changing a person's hair color, using lightener or haircolor to lift the level or brightness of hair strands. Hair colorants primarily come in to different forms: oxidative (permanent) and non-oxidative (semi-permanent and temporary).Permanent hair dyes bleach and add a new color to hair through the penetration of smaller dye precursors into the cortex and subsequent oxidation.^[1] There are four basic types of highlights: foil highlights, hair painting, frosting, and chunking. Highlights can be any color, as long as it is a lighter level than the surrounding hair. Hair lightened with bleach or permanent color will be permanent until new growth begins to show. Highlighted hair can make the hair appear fuller. Therefore, it is sometimes recommended for people with thin and fine hair.
