Global Hair colour service is a method of dying your hair in a single colour from root to tip. Global hair colour is a fairly basic technique that is usually done to cover up greys or provide a uniform base for subsequent colouring. The treatment, which can take anywhere from one to two hours, should be done by an expert. Global colouring can cost anywhere from three to seven thousand dollars, depending on the length of your hair.
