"Highlights" is a general term that refers to strands of hair that are lighter than the base color they're being laid upon. A highlight only refers to a color that's not as dark as the base strands. The size of the highlights, the level of lightness, the tone, and the placement are all left up to you. Highlights aren't a one-size-fits-all, and neither is the way they are administered. The type of highlight depends on a number of things: * The look you want * The kind of hair you have * How blonde you wish to go.
