The production of hair dye, encompassing permanent, semi-permanent, and temporary colorations, is a meticulous process requiring the precise blend of various components. This operation leverages equipment such as mixers, homogenizers, reactors, and centrifuges, along with other specialized machinery.
The journey towards a finished hair dye product starts with the selection of suitable ingredients to achieve the desired hue. These components are then blended in a mixer to achieve a uniform consistency. Following this, the mixture is subjected to high pressure and shear forces in a homogenizer to ensure the even distribution of particles. The mixture then moves into a reactor where it’s heated and agitated until it achieves the necessary consistency. The final step involves passing the mixture through a centrifuge to separate any impurities before packaging the product for the market.
