Technology for the production of hair dyes Hair dyes are divided into 3 types: permanent, semi-permanent and tinted. This basic classification depends on the chemical components of the paint, the constituent elements and the purpose of their use. For example, permanent, permanent hair dyes contain ammonia and amines, whichchange the structure of the hair and dye it for a long time.
