Abstract: A system to highlight the hair includes a device (10) and a composition (50). The device (10) includes a first portion movably joined to a second portion. Composition (50) includes a percentage of hydrogen peroxide and a percentage of an alkalizer by weight of the composition (50). The weight percentages of hydrogen peroxide and of an alkalizer are defined by equation (I): X+1.5Y?15 (I). X is the percentage by weight of hydrogen peroxide by weight of the composition (50). Y is the percentage by weight of an alkalizer by weight of the composition (50). The composition (50) includes at least 2% of hydrogen peroxide by weight of the composition (50) and the alkalizer is an inorganic salt. The composition (50) allows to perform highlighting when applied with the device (10).
