If bright red is not your favorite, then you could try Mahogany shade from Wella Koleston's color cream kit. Mahogany shade, which is one of the most popular shades of red, is darker than bright red and goes well with dark colored hair. The hair dye is made to last up to 8 weeks long. It is manufactured with the deep-fusion technology. The color pigment sticks to the surface and helps your hair stay brightly colored for a long time. You may notice a shimmer-like surface of hair in the sunlight.
