Despite being a truly innovative way of cleansing hair, Shampoo Bars are still a relatively unknown quantity. D R Harris is seeking to remove the mystique with their Rosemary Shampoo Bar, a compact and long-lasting means of concentrated hair care. All it requires is water to produce a truly impressive lather, while its liquid-free composition makes it an invaluable addition while travelling. Utilising Rosemary to create its gorgeous aroma, the ingredient also serves as invigorating touch to the dullest hair.
