BES REGAL ZERO

The formulation of REGAL ZERO does not contain the pigment PPD (Paraphenylenediamine), the main responsible for allergic phenomena and irritations, but innovative coloring pigments that properly associated have allowed to obtain bright and luminous colors with extremely natural shades and reflections. REGAL ZERO contains a greater quantity of coloring pigments than other permanent haircolor with or without ammonia. For this reason, it needs a higher concentration of hydro-gen peroxide (activator or developer). This explains why REGAL ZERO is used with a 1:1,5mixing ratio with the selected activator.
The coloring pigments contained in REGAL ZERO are bigger, larger than those of other hair dyes with ammonia. For this reason, REGAL ZERO requires a longer laying time (35-45minutes). In this way, the coloring pigments have more time to penetrate into the hair and bind each other through the oxidative process.
