CERIS PEROXIDE / DEVELOPER

In any discussion of hair colour, it is important to talk about colour level and developer. Level refers to the lightness or darkness of a particular hair colour. It?s shown on a scale of one to ten with 1 being black and 10 being palest blonde. The hair colour formulas available also have a level on this same scale. This tells you how light or dark the finished colour will be. Developer is the oxidizing agent that allows the hair colour to do its job. Most permanent hair colour today uses hydrogen peroxide as a developer. The peroxide opens the cuticle so that the colour can penetrate. It also disperses the existing colour and can lighten the hair?s colour level depending on the strength of the peroxide formulation. The peroxide developer?s oxidizing potential is denoted as its ?volume?. Most hair colour formulas work with a 10, 20, 30 or 40 volume developer, which means adding different quantities of oxygen atoms to the mixture. To be used following the directions of the product with which it has to be mixed and wearing protective mono gloves. Keep out of the reach of children. The oxygen allows Ceris Hair Colour Cream to perform the following actions: ? COLOURING ACTION ? When the colourants come in contact with the oxygen they create colour. ? LIGHTENING ACTION ? The ammonium hydroxide (ammonia) in the product is a catalyst for the oxygenated water. Upon contact with the ammonia, CERIS PEROXIDE quickly releases its oxygen atoms, which acts on the natural melanin in the hair, lightening it.
