Choosing the right hair colour shade may be a complicated task, and usually you need to ask a professional to make the right decision. L’Oréal Paris USA is helping ladies to choose the care product that fit them best in a new digital integration 2012 Hair Color Census campaign launched on Facebook and Pinterest. The cosmetics giant is encouraging brunettes, blondes and redheads to get engaged in the promotion by joining one of the ‘hair tribes’ to celebrate their haircolour.
