Hair colouring is the practice of changing the colour of hair.
The main reasons for this practice are cosmetic (e.g., to cover gray hair, to change to a colour regarded as more fashionable or desirable, or to restore the original hair colour after it has been discoloured by hairdressing processes or sun bleaching).
Hair tinting, is an ancient art. Today, hair colouring is immensely popular, with over 75 percent of women colouring their hair.
