  • a method of colouring hair comprising contacting hair with an iron salt followed by contacting with gallic acid or an ester thereof, is known. Such a method gives a bluish tinge to the hair which is not liked by some consumers. Consumers generally prefer a more brownish tinge which they believe gives one a natural look. The present inventors have found that giving a high pH treatment to the well known two step process of colouring hair provides the much needed brownish tinge.

  • Preferred colour to be achieved as per the present invention is brown with a minimal blue tint.
