Highlights refer to hair that is lighter than the base color. Contrary to popular belief, highlights are not just for blondes, but can refer to lightening strands of any shade of hair. Highlights are traditionally applied using a method called “foiling,” in which sheets of foil are used to separate strands of hair that have been covered with a color or lightener before wrapping them in the foil to process. The foil keeps the lightener from getting on the surrounding hair, and also allows the lightener to lift more effectively. Foil highlights are generally placed close to the scalp, lightening the hair from the roots to the ends for an all-over highlighted look.
Balayage is a free-hand technique of applying highlights, and does not usually use foil to separate the hair. Balayage creates soft and natural gradation of lightness along the hair strand—usually slightly deeper closer to the scalp and lighter towards the ends. Typically, balayage starts away from the roots and is focused towards the mid-shafts and ends of hair.
