Brown Jasper Semi-Permanent Hair Colours Named for a material often used in Ancient Egyptian jewellery, Brown Jasper’s rich, mahogany-brown shine, uplifted by subtle hints of red, delivers timeless luxury – an evocative twist on the classic brunette. For the most vivid results, we recommend applying to pre-lightened hair. The colour on the pot is a simulation of the colour on a level 10. Our Rich Naturals range delivers even coverage and contains a deep-conditioning formula that nourishes hair from the first application.
