Hennaplus Colour Boost When colouring the hair, the colour always is most beautiful and intense immediately after the colouring treatment. In the period in between two colourings the colour result will gradually fade. It will become less intense, dull and outgrowth will appear. The frequency in which the hair is washed and the condition of the hair will have their effect on this process.
