Colourless Pre Colour removes permanent and semi-permanent oxidative hair colours and deeply cleans the hair so that the hair is optimally prepared for the next colouration. The product is suitable for all hair types. Simply wash out your unwanted colouring with the Colourless hair colour remover. Then you can dye your hair directly as you like. How does the hair colour remover work? Colourless minimises the artificial colour pigments in the hair, so they can be easily rinsed out. Colourless does not attack your natural colour pigments and you will receive the shade that was under the artificial colour. Please note: Colourless is designed to remove oxidative hair colours. Colourless cannot remove direct colours (including henna) and is also not suitable for Afro hair. If you have applied a very dark colour or a fashion colour such as fire red or black to discoloured, porous or grey hair, the cuticle (outermost cuticle layer) may have permanent stains. Colourless cannot remove stains on the cuticle. Use 2 packs for hair that is longer than shoulder length or very thick. In case of accumulation of paint, repeated application may also be required. Colourless can only return your brightest shade. If you have previously discoloured or lightened your hair, Colourless will not be able to restore your natural colour pigmentation. Colourless does not contain peroxides or ammonia compounds and cannot lighten your hair. Any lightening or changes in the hair interior (after application of Colourless) are due to previous colour applications.
